URGENT will give brilliant mark For the reaction 2Na + Cl2 ------ 2NaCl, how many grams of sodium chloride can be produced from 500g of chlorine? ( atomic masses : Na = 23 , Cl = 35.5 g/mol) *

1 point

112 g

319 g

409 g

825 g​

Answers

Answer 1

Answer:

825 g

Step-by-step explanation:

Here's my work:

500g Cl2 l   1mol Cl2  l  2 mol NaCl   l  58.5 g NaCl

                l   71 g Cl2    l  1 mol Cl2      l    1 mol NaCl  

= 823.94  - the rounding can be a little off

The first thing you have to do is convert the 500 g of Cl2 into moles.  So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71.   now on the third column you are comparing the mol ratios of the equation.  The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a  coefficient of 2 in front of NaCl so that means there is 2 moles.  Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl .  You multiply across the top  and then divide that number by the bottom row.

angle A = 41.0 degrees

Side AC = 9.1 yd

Side CB = 7.3 yd

Explanation:

11) angle C = 84 degrees

andle B = 55 degrees

angle A + angle B + angle C = 180 degrees (sum of angles in a triangle)

angle A + 55 + 84 = 180

angle A + 139 = 180

angle A + 139-139 = 180 -139

angle A = 180 -139

angle A = 41 degrees

angle A = 41.0 degrees (nearest tenth)

To find side AC, we apply sine rule

c = AB = 11 yd

AC is the side opposite angle B. It is represented by b in the formula

c/sinC = b/sinB

11/sin84 = b/sin55

b = (11/sin84)(sin55)

b = 11(0.8191)/(0.9945)

b = 9.06

Side AC = b = 9.1 yd (nearest tenth)

To find side CB, we apply sine rule

a = CB

a/sinA = c/sinC

a/sin 41 = 11/sin84

a = (11/sin84)(sin 41)

a = 7.26

Side CB = a = 7.3 yd (nearest tenth)

Simplify the expression \((\frac{64x^{12} }{125x^{3} } )^{\frac{1}{3} }\) . Assume all variables are positive

Answers

To simplify the expression \(\left(\frac{64x^{12}}{125x^{3}}\right)^{\frac{1}{3}}\), we can start by simplifying the numerator and denominator separately.

In the numerator, we have \(64x^{12}\). We can rewrite 64 as \(4^3\) and \(x^{12}\) as \((x^3)^4\). So, the numerator becomes \(4^3 \cdot (x^3)^4\).

In the denominator, we have \(125x^{3}\). We can rewrite 125 as \(5^3\) and \(x^{3}\) as \((x^3)^1\). So, the denominator becomes \(5^3 \cdot (x^3)^1\).

Now, let's simplify the expression inside the parentheses: \(4^3 \cdot (x^3)^4 \div (5^3 \cdot (x^3)^1)\).

Simplifying each part further, we have:

\(4^3 = 64\),

\((x^3)^4 = x^{12}\),

\(5^3 = 125\), and

\((x^3)^1 = x^3\).

Now the expression becomes:

\(\frac{64x^{12}}{125x^3}\).

To simplify further, we can cancel out the common factors in the numerator and denominator. Both 64 and 125 have a common factor of 5, and x^12 and x^3 have a common factor of x^3. Canceling these common factors, we get:

\(\frac{64x^{12}}{125x^3} = \frac{8}{5} \cdot \frac{x^{12}}{x^3} = \frac{8}{5}x^{12-3} = \frac{8}{5}x^9\).

Therefore, the simplified expression is \(\frac{8}{5}x^9\).

How many ways to draw?

There are 52 ways to draw the first card from a standard deck of 52 cards. Each card in the deck is distinct, so there are 52 different possibilities for the first card.

The deck consists of 4 suits (diamonds, hearts, spades, and clubs) with 13 cards in each suit. Therefore, there are 13 cards of the spades suit. Since each card is equally likely to be drawn, the probability of drawing a spade as the first card is 13/52 or 1/4.

This is because out of the 52 possible cards, 13 of them are spades. So, regardless of the specific spade that is drawn, there are 13 ways to draw a spade as the first card.

Therefore,  subscript indices must be either positive integers or logical. True

Explanation: The statement "subscript indices must be either positive integers or logicals" is true. Subscript indices are used to identify elements in an array. A positive integer subscript identifies a particular element in an array, while a logical subscript identifies a subset of elements based on a logical condition. For example, if we have an array A, then A(1) would identify the first element of the array, while A(A > 0) would identify all elements in the array that are greater than zero. Subscript indices cannot be negative or non-integer values.

Step-by-step explanation:

A dialtion either reduces or enlarges the dimensions of a shape, causing for them to no longer be congruent.

A reflection wouldn't change the congruency of the shape since it is just reflecting it across whatever axis. The dimensions stay the same.

A rotation would simply rotate/turn the shape. The dimensions would not be changed.

A translation would slide the shape elsewhere whether it be vertically, horizontally, or diagonally. The dimensions would not change.

When testing for NULL values to find Customers who have no Orders, which column is best to include in the WHERE clause below: WHERE __________ IS NULL

Answers

When testing for NULL values to find Customers who have no Orders, which column is best to include in the WHERE clause below:

WHERE __________ IS NULL

The primary key from the Orders table

The correct answer to the question is (b) IS NOT NULL.  This operator is used in SQL queries to find the rows that have a value in the specified column, i.e., the rows that are not null.

A null value represents an unknown or missing value, and it can be assigned to a column when there is no data available for that attribute. In SQL, null values are not equivalent to zero or an empty string, and they cannot be compared using the regular comparison operators. Hence, the IS NOT NULL operator is used to filter out the rows that have a valid value in the specified column.  For example, if we have a table of employees with columns such as employee_id, first_name, last_name, and department_name, we can use the IS NOT NULL operator to find the employees who have a valid department_name assigned to them. The query would be:

SELECT employee_id, first_name, last_name

FROM employees

WHERE department_name IS NOT NULL;

This query would return all the rows from the employees table where the department_name column is not null, i.e., the employees who have a department assigned to them. In summary, the IS NOT NULL operator is used to filter out null values from a column and retrieve the rows that have valid data.

E The matrix equation Ax = 0 has only the trivial solution. F. All columns of the matrix A are pivot columns.

Answers

The statements that are equivalent to the statement that a set of vectors (v1, ..., vp) is linearly independent are:

A. A linear combination of vi, ..., vp is the zero vector if and only if all weights in the combination are zero.

B. The vector equation x₁v₁ + x₂v₂ + ... + xₚvₚ = 0 has only the trivial solution.

F. All columns of the matrix A are pivot columns.

Let's examine each option to see why they are equivalent:

A. A linear combination of vi, ..., vp is the zero vector if and only if all weights in the combination are zero.

This statement is equivalent to linear independence because it states that the only way for the linear combination of the vectors to equal the zero vector is if all the weights are zero. In other words, there are no nontrivial solutions to the equation c₁v₁ + c₂v₂ + ... + cₚvₚ = 0, where c₁, c₂, ..., cₚ are the weights.

B. The vector equation x₁v₁ + x₂v₂ + ... + xₚvₚ = 0 has only the trivial solution.

This statement is also equivalent to linear independence because it states that the only solution to the equation is the trivial solution where all the variables x₁, x₂, ..., xₚ are zero. In other words, there are no nontrivial solutions to the homogeneous system of equations represented by the vector equation.

F. All columns of the matrix A are pivot columns.

This statement is equivalent to linear independence because it implies that every column of the matrix A is a pivot column, meaning that there are no free variables in the corresponding system of equations. This, in turn, implies that the only solution to the homogeneous system Ax = 0 is the trivial solution, making the set of vectors linearly independent.

The other options (C and E) are not equivalent to the statement that a set of vectors is linearly independent:

C. There are weights, not all zero, that make the linear combination of vi, ..., vp the zero vector.

This statement describes linear dependence rather than linear independence. If there are non-zero weights that result in the linear combination of the vectors equaling the zero vector, it means that the vectors are linearly dependent.

E. The matrix equation Ax = 0 has only the trivial solution.

This statement is related to the linear dependence of the columns of the matrix A rather than the linear independence of the vectors (v1, ..., vp). It refers to the homogeneous system of equations represented by the matrix equation and states that the only solution is the trivial solution, implying that the columns of A are linearly independent. However, it does not directly correspond to the linear independence of the original set of vectors.

In summary, the statements A, B, and F are equivalent to the statement that a set of vectors (v1, ..., vp) is linearly independent.

Answer:

To graph this inequality, you can start by graphing the related function y = -x^2 - 1. This is a downward-facing parabola that opens downwards and has a vertex at (0, -1).

To graph the inequality y ≥ -x^2 - 1, you need to shade the region above the graph of the parabola. This is because any point above the parabola will have a y-coordinate that is greater than or equal to the corresponding y-coordinate on the parabola.

So, to graph the inequality, you can shade the region above the parabola. You can use a dotted line to represent the boundary of the inequality, since the inequality includes the possibility of equality (y = -x^2 - 1).

\(A = P( 1 + rt )\\\\r = \frac{1}{t}( \frac{A}{P} -1 ) \\\\r = \frac{1}{5}( \frac{40000}{20000} -1 ) \\\\r = \frac{1}{5}( 2 -1 ) \\\\r = \frac{1}{5}\\\\r = 0.2 \\\\\)

Converting r decimal to R a percentage

Rate R = 0.2 × 100%

Rate r = 20% per year

Therefore, the interest rate is 20% per year.

write the number positioned at point A

Answers

The number positioned at point A is -4.25.

What is a number line?

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used to compare two numbers such as 4 and 1. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.

In this scenario, the given number line uses a scale of 1:0.25. Therefore, the number (numerical value) that is placed at point A is given by:

Point A = -4.5 - 0.25

Point A = -4.25.

The following system of periodic tasks are to be scheduled and executed according to structured cyclic schedule with fixed frame size. (5, 1), (7, 1), (12,0) and (45,9). Determine the appropriate frame size for the given task set?

Answers

The appropriate frame size for the given task set is 140.

The frame size is the length of a time interval in which all the tasks in the system are scheduled to be executed. The frame size must be a multiple of the period of each task in the system.

In this case, the periods of the tasks are 5, 7, 12, and 45. The smallest common multiple of these periods is 140. Therefore, the appropriate frame size for the given task set is 140.

Here is a more detailed explanation of the calculation of the frame size:

The first step is to find the least common multiple of the periods of the tasks. The least common multiple of 5, 7, 12, and 45 is 140.

The second step is to check if the least common multiple is also a multiple of the execution time of each task. The execution time of each task is equal to its period in this case. Therefore, the least common multiple is also a multiple of the execution time of each task.

Therefore, the appropriate frame size for the given task set is 140.
