The amount of sucrose required will be 12.5 grams and the mass of water required will be 250 g.

5% by mass glucose solution is to be prepared. This means that 5g of glucose will be dissolved in 100 mL of water.

250g of such a solution will require 250 mL of water.

5% of 250g = 5/100 x 250 = 12.5 grams

Thus, the solution is prepared by dissolving 12.5 grams of sucrose in 250 grams (250 mL) of water.

A 1200 mL IV drip is labelled to contain 12% of a laxative. The number of mL of the IV drip that should be administered if a patient is to receive 21 mL of the laxative is 175 mL.

To find the number of mL of the IV drip that should be administered to provide 21 mL of the laxative, we can set up a proportion using the concentration of the laxative.

Let x represent the number of mL of the IV drip to be administered.

The concentration of the laxative is given as 12% or 0.12, meaning that in 100 mL of the IV drip, there are 12 mL of the laxative.

Using the proportion:

(12 mL of laxative) / (100 mL of IV drip) = (21 mL of laxative) / (x mL of IV drip)

Cross-multiplying, we get:

12 mL * x mL of IV drip = 100 mL * 21 mL of laxative

12x = 210 IV drip0

Dividing both sides by 12:

x = 2100 / 12

x = 175

Therefore, 175 mL of the IV drip should be administered to provide 21 mL of the laxative.

The NO bond length in  \(\rm N-O\) (115 pm) is shorter than that in  \(\rm [NO][Na]\) (119 pm) due to the difference in the electronic structure of the two compounds.

A molecular orbital diagram is a graphical representation of a molecule that shows its constituent atoms and the bonds between them.

In \(\rm N-O\), the bond is a covalent bond, meaning that the electrons are shared between the nitrogen and oxygen atoms. In contrast, the bond in  \(\rm [NO][Na]\) is an ionic bond, meaning that the electrons are transferred from one atom to another.

In an ionic bond, the atoms are held together by the electrostatic attraction between the positively charged and negatively charged ions. The presence of the sodium ion in \(\rm [NO][Na]\) causes the NO bond to be longer due to the repulsion between the negatively charged oxygen atom and the positively charged sodium ion.

Therefore, the NO bond in \(\rm N-O\), is shorter than that in \(\rm [NO][Na]\) due to presence of sodium ion in  \(\rm [NO][Na]\) which causes repulsion between the negatively charged oxygen atom and the positively charged sodium ion resulting into longer NO bond.

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

RxN:   Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O

Given:   3.01 moles H₂O

Step 2: Balance RxN

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

Step 3: Define conversions

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 4: Stoichiometry

\(3.01 \ mol \ H_2O(\frac{1 \ mol \ H_2SO_4}{2 \ mol \ H_2O} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )\) = 147.625 g H₂SO₄

Mass of lime produced = 19.0 g

Explanation:

Given data:

Mass of lime produced = 11.2 g

Mass of limestone react = ?  

Solution:

Chemical equation:

CaCO₃     →      CaO + CO₂

Balanced chemical equation:

CaCO₃     →      CaO + CO₂

Number of moles of lime:

Number of moles = mass / molar mass

Molar mass of lime 56.1 g/mol

Number of moles = 11.2 g/ 56.1 g/mol

Number of moles = 0.19 mol

Now we will compare the moles of CaO and CaCO₃  from balance chemical equation.

                    CaO        :           CaCO₃

                      1             :             1

                     0.19          :          0.19

Mass of limestone react:

Mass = number of moles × molar mass

Mass = 0.19 mol × 100.1 g/mol

Mass = 19.0 g

Answer:

Explanation:

Just add all atomic mass used in the formula together: 2*(14+16*3)+88= 2*62+88=124+88=210

Hope this was helpful

The relative formula mass of strontium nitrate Sr(NO₃)₂ is 210

The relative atomic masses of N, O and Sr are 14,16 and 88 respectively.

In calculating the relative atomic mass of an element with isotopes, the relative mass and proportion of each is taken into account. Adding the atomic masses together gives the relative formula mass of a compound

So, relative atomic mass of Sr(NO₃)₂ is calculated as

88+ 2(14+16×3) = 210

The atomic mass constant (symbol: mu) is defined as being 1/12 th of the mass of a carbon-12 atom. Since both quantities in the ratio are masses, the resulting value is dimensionless; hence the value is said to be relative atomic mass.

The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.

The empirical formula is C₄H₄O.

To find the empirical formula of methyl benzoate, we'll follow these steps:

Step 1: Convert mass to moles
Carbon: 3.758 g / 12.01 g/mol (molar mass of C) = 0.313 moles
Hydrogen: 0.316 g / 1.008 g/mol (molar mass of H) = 0.313 moles
Oxygen: 1.251 g / 16.00 g/mol (molar mass of O) = 0.078 moles

Step 2: Divide by the smallest mole value (0.078 moles)
Carbon: 0.313 moles / 0.078 = 4.01
Hydrogen: 0.313 moles / 0.078 = 4.01
Oxygen: 0.078 moles / 0.078 = 1.00

Answer:

Because  they convert the electrical voltage produced by increasing and then it goes into the power lines

Explanation:

The main purpose of the transformers is to convert high electrical voltage to low voltage. The transformers transfer the electrical energy into power lines.

A transformer can be described as a passive component that transfers electrical energy from one electrical circuit to another circuit or multiple circuits. A varying current produces a varying magnetic flux in the transformer's core, which induces an electromotive force (EMF) across other coils wound around the same core.

When the electricity is generated in the power plant, it has to travel large distances from the stations for supply. The high voltage transmission is more efficient as it allows transmitting a larger part of the generated power.

From the power stations, first, the current is passed through the step-up transformer, then at the high voltage, the current reaches the substations, where the current is traveled through the step-down transformer where the voltage is decreased to an amount of 220V.

0.99 moles of copper (Cu) would be made when 0.33 mole of copper (II) phosphide (Cu3P2) deteriorates.

Copper (II) phosphide (Cu3P2) is a compound that can be made through a reaction between copper and phosphorus under controlled conditions. It can also be made by the reaction between copper sulfate and sodium hypophosphite or by reducing copper (II) phosphate with carbon at high temperatures.

Copper (II) phosphide (Cu3P2) has several uses. It is used as a rodenticide to control rodents, as a catalyst, as a lubricant, as an alloying agent, and as a pigment in some ceramic glazes.

The decomposition of copper (II) phosphide (Cu3P2) can be represented by the following chemical equation Cu3P2 → 3Cu + 2P.

The number of moles of copper produced when 0.33 mole of copper (II) phosphide decomposes will be:

0.33 moles Cu3P2 / 1 x 3 moles Cu / 1 mole Cu3P2 = 0.99 moles Cu

Increase and decrease in pressure

Explanation:

The factors that cause transitions between the solid and liquid state are:

1. The increase in pressure of most liquids can lead to the transition to the solid phase. This is because, in general, an increase in pressure promotes the formation of a denser phase, which is the solid state in this case.

2. The decrease in pressure of most liquids can lead to the transition to the solid phase. This is not as common, but certain substances may undergo this transition.

The electrons in the shells would experience a decrease in energy.

We know that the electron shell in the outermost part of the atom is the shell that gets involved in the bonding of the atom. When the bonding takes place, there could be the sharing of electrons as in the covalent bond or the transfer of electrons as in the ionic bond.

In this case, we are dealing with the covalent bond hence there is the sharing of electrons and the shells that would be involved in this is the outermost shells.

By virtue of the sharing of the electrons and the combination of the shells, the energy of the outermost shell would become reduced as the electrons are now attracted to two nuclei rather than one of the hydrogen atoms in the compound.
