The formula for a hydrate : NiSO₄. 7H₂O

<h3>Further explanation</h3>

Given

55.2% NiSO₄, and 44.8% H₂O

Required

The formula

Solution

MW NiSO₄ = 154,75 g/mol

MW H₂O = 18 g/mol

Mol ratio :

NiSO₄ : 55.2 : 154,75 g/mol = 0.357

H₂O : 44.8 : 18 g/mol = 2.49

Divide by 0.357 :

NiSO₄ = 0.357/0.357 = 1

H₂O = 2.49/0.357 = 7

If a solution is 65 Liters and has 13 moles of NaCl dissolved in it what is the molarity of NaCl in this solution? *
svlad2 [7]

Answer:

Molarity = 0.2 M

Explanation:

Given data:

Number of moles of NaCl = 13 mol

Volume of solution = 65 L

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

now we will put the values in formula.

Molarity = 13 mol / 65 L

Molarity = 0.2 mol/L

   mol/L = M

Molarity = 0.2 M

For the conversion of ice to water at 0°C and 1 atm,1.ΔG is negative,ΔH is negative, and ΔS is positive.2.ΔG is zero, ΔH is posi
Arturiano [62]

Answer:

2. ΔG is zero, ΔH is positive, and ΔS is positive

Explanation:

When the ice is being converted to water ate 0ºC and 1 atm, there is an equilibrium between the solid and the liquid. At the equilibrium point, ΔG (the free energy) is zero. It is negative for spontaneous reactions and positive for nonspontaneous reactions.

For the phase change happens, the ice must absorb heat from the surroundings, so it's an endothermic reaction, and because of that ΔH (the enthalpy) must be positive. It is negative for exothermic reactions.

In the liquid state, the molecules have more energy and the randomness is higher than the solid-state. The entropy (S) is the measure of the randomness, so if it's increasing, ΔS must be positive.

What units can NOT be derived from a balanced chemical equation-
elena-14-01-66 [18.8K]

Answer:

D) Volume of gas

E) Temperature

Explanation:

A balanced chemical equation can provide the following information :

The reactants and products through their symbols and formulae. The ratio of molecules of reactants and products. As molecular masses are expressed in unified mass (u), the relative masses of reactants and products are known from the equation.
