Answer:
2.65 M
Explanation:
Convert grams of K₂CO₃ to moles. The molar mass is 138.205 g/mol.
(110 g)/(138.205 g/mol) = 0.796 mol
Convert milliliters of solution to liters.
300 mL = 0.300 L
Divide moles of K₂CO₃ by liters of solution.
0.796 mol/0.300 L = 2.65 mol/L = 0.265 M
Answer:
2.7 M
Explanation:
M=moles of solute/volume of solution (L)
First, you need to calculate the number of moles using the given mass and the molar mass.
110 g138.205 g/mol=0.80 mol
Then, you can solve for molarity using the molarity equation.
M=0.80 mol0.300 L=2.7 M
Remember, you need to convert mL to L before you can calculate molarity.

What volume will 12 g of oxygen gas (O2) occupy at 25 °C and a pressure of 53 kPa?
Answers
ANSWER
The volume of the oxygen gas is 17.5 L
EXPLANATION
Given that;
The mass of oxygen gas is 12 grams
The temperature of the gas is 25 degrees Celcius
The pressure of the gas is 53 kPa
To find the volume of the oxygen gas, follow the steps below
Step 1; Assume the gas behaves like an ideal gas
Therefore, apply the ideal gas equation to find the volume of the gas
\(\text{ PV }=\text{ nRT}\)Where
P is the pressure of the gas
V is the volume of the gas
n is number of moles of the gas
R is the universal gas constant
T is the temperature of the gas
Step 2: Find the number of moles of the oxygen gas using the below formula
\(\text{ mole }=\text{ }\frac{\text{ mass}}{\text{ molar mass}}\)Recall, that the molar mass of the oxygen gas is 32 g/mol
\(\begin{gathered} \text{ mole }=\text{ }\frac{12}{\text{ 32}} \\ \text{ mole }=\text{ 0.375 mol} \end{gathered}\)Step 3; Convert the temperature to degree Kelvin
\(\begin{gathered} \text{ T }=\text{ t }+\text{ 273.15} \\ \text{ t }=\text{ 25}\degree C \\ \text{ T }=25\text{ }+\text{ 273.15} \\ \text{ T }=\text{ 298.15K} \end{gathered}\)Step 4; Substitute the given data into the formula in step 1
Recall, that R is 8.314 L kPa K^-1 mol^-1
\(\begin{gathered} \text{ 53 }\times\text{ V }=\text{ 0.375}\times\text{ 8.314}\times\text{ 298.15} \\ \text{ 53V }=\text{ 929.557} \\ \text{ Divide both sides by 53} \\ \text{ }\frac{\cancel{53}V}{\cancel{53}}\text{ }=\text{ }\frac{929.557}{53} \\ \text{ V }=\text{ }\frac{929.557}{93} \\ \text{ V }=\text{ 17.5 L} \end{gathered}\)Hence, the volume of the oxygen gas is 17.5 L

Answers
The value of Kc for the reaction at 25°C is 11.25.
The equilibrium constant expression for the reaction:
2NO(g) + \(Cl_2\)(g) ⇌ 2NOCl(g)
is Kc = \(([NOCl]^2)/([NO]^2[Cl_2])\), where [NO], [\(Cl_2\)], and [NOCl] are the molar concentrations of NO, \(Cl_2\), and NOCl, respectively, at equilibrium.
At 25°C, if the concentration of NO and \(Cl_2\) are 0.2 M and the concentration of NOCl is 0.3 M, then we can substitute these values into the equilibrium constant expression to find the value of Kc:
Kc =\(([NOCl]^2)/([NO]^2[Cl_2])\)
Kc = \((0.3^2)/(0.2^2*0.2)\)
Kc = 11.25
Therefore, the value of Kc for the reaction at 25°C is 11.25.

N2(g) + 3 H2(g) ⇌ 2 NH3(g)
Answers
The value of Kc for the given reaction is 0.0579 (rounded to four decimal places).
The formula for the equilibrium constant, Kc, of a reaction is given by the ratio of the product of the concentrations of the products raised to their respective stoichiometric coefficients to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.
The stoichiometric coefficients are the coefficients in the balanced chemical equation.
To determine the value of Kc for the reaction given by the following chemical equation:N2(g) + 3 H2(g) ⇌ 2 NH3(g)
we first need to write the expression for Kc.
The expression for Kc is given by the following formula:Kc = [NH3]² / [N2][H2]³.
We are given the equilibrium concentrations as follows:[N2]eq = 2.66 M[H2]eq = 0.64 M[NH3]eq = 3.34 M
We can substitute these values into the expression for Kc and obtain the following:Kc = (3.34)² / (2.66)(0.64)³ = 0.0579 (rounded to four decimal places).

The ranking of boiling point is based on the molecular weight and intermolecular forces between molecules.
2 central carbons, each with CH3 bonded to them. A central C has H bonded left, above, behind to the right, and in front to the right. A carbon chain with 5 central carbons, with CH3 bonded to the first, second, and last carbons in the chain. 2 central carbons with CH3 bonded to the outside, and CH3 bonded to the leftmost inside carbon.
In this case, all compounds are hydrocarbons, meaning they are non-polar molecules and exhibit van der Waals forces. However, the length of the carbon chain and the arrangement of atoms in the molecule affect the magnitude of these forces.
The first compound has only two carbons and exhibits weak intermolecular forces, so it has the lowest boiling point. The second compound has three carbons and a more complex arrangement of atoms, resulting in slightly stronger van der Waals forces and a higher boiling point.
The third compound has a longer carbon chain, which increases the molecular weight and results in stronger intermolecular forces, giving it a higher boiling point than the previous two. The fourth compound has the longest carbon chain and has multiple branches, which increases the surface area of the molecule and the strength of the intermolecular forces, giving it the highest boiling point.

The amount of protons in the atoms' nucleus, of this substance, is 33. Since there are 33 electrons in a neutral atom, arsenic-neutral atoms, which have an equal amount of protons and electrons, are neutral.
When an atom is free of all charges, it is considered to be neutral. Ions are named when an atom has a charge on it. As a result, an atom is said to be neutral if it is in its initial state, which is one in which an electron has neither lost nor gained.
Any other atom may contain the same subatomic species that a neutral atom does. Electrons, protons, and neutrons make up the subatomic species. The distinction is that neutral atom have the same number of positive species as negative species, which cancels out all charges. A neutral atom thus has the same number of protons and electrons as a charged atom.

mass number is the 'number of protons + number of neutrons'
now this will help you do the first question
if you do 16 -8 = 8 ( that's how she got 8 neutrons)
another thing you need to know is that all the time the number of protons = the number of electrons ( they are the same)
this will help you answer table 2
for fluorine it says there are 9 electrons, you automatically have to think 9 electrons means 9 protons too, ( I think she has got that wrong, it's supposed to be 9 protons not 19)
if you have 9 protons and the given 10 neutrons and add them together you will get the mass number which is supposed to be 19
then if you try out the same rules for argon you will see they work - the number of electrons and protons are same and when you find out the protons, you can just take that away from the mass number ( which is number of protons + neutrons) to get just the number of neutrons.

What forms of energy are produced when
fossil fuels burn?
Answers
When fossil fuels burn, several forms of energy are produced, including:
Heat energy: The primary form of energy released during fossil fuel combustion is heat. Fossil fuels contain chemical energy stored for millions of years, and when they burn, this energy is released in the form of heat. The heat energy can be harnessed for various purposes, such as heating buildings or generating steam to drive turbines.
Light energy: Burning fossil fuels can also produce light energy in the form of flames or glowing embers. This light energy is a byproduct of combustion.
Mechanical energy: Heat generated by burning fossil fuels can be converted into mechanical energy. This is typically achieved by using heat to produce steam, which drives a turbine connected to a generator. The rotating turbine converts the heat energy into mechanical energy, which is further transformed into electrical energy.
Electrical energy: Through the process described above, burning fossil fuels can ultimately generate electrical energy. The mechanical energy produced by the turbine is converted into electrical energy by the generator. Electrical energy can power various devices, appliances, industries, and infrastructure.
It's critical to note that while burning fossil fuels can produce useful forms of energy, it also results in the release of carbon dioxide and other greenhouse gases. This contributes to climate change and environmental concerns. As a result, there is a global shift towards cleaner and renewable energy sources to mitigate these negative impacts.

Determine the empirical formula of the compound formed when 1.2g of magnesium reacts with 3.55g of chlorine.Take the molar mass of magnesium and chlorine to be 24g and 35.5g respectively.
Answers
Explanation:
For Mg, (1.2 g Mg/24 g Mg) = 0.05 mol Mg.
For Cl, (3.55 g Cl/35.5 g Cl) = 0.1 mol Cl
So the ratio now is
Mg:Cl = 0.05 : 0.1 = 1:2
I got the 1:2 ratio by dividing both by the smallest number, which is 0.05 mol. Therefore, the empirical for formula of the substance is \(MgCl_2\)
The empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.
To determine the empirical formula of the compound formed when magnesium (Mg) reacts with chlorine (Cl), we need to find the ratio of the elements in terms of moles.
First, we calculate the number of moles of each element:
Moles of Mg = Mass of Mg / Molar mass of Mg
Moles of Mg = 1.2 g / 24 g/mol
Moles of Mg = 0.05 mol
Moles of Cl = Mass of Cl / Molar mass of Cl
Moles of Cl = 3.55 g / 35.5 g/mol
Moles of Cl = 0.1 mol
Next, we determine the simplest whole-number ratio between the moles of Mg and Cl:
Mg:Cl = 0.05 mol : 0.1 mol
To simplify the ratio, we divide both values by the smaller value (0.05 mol in this case):
Mg:Cl = 0.05 mol / 0.05 mol : 0.1 mol / 0.05 mol
Mg:Cl = 1 : 2
Therefore, the empirical formula of the compound formed when magnesium reacts with chlorine is MgCl₂.
