Answer:

Rate of the reaction= 9.92× 10^-5 M² min-1

Explanation:

Using the equation of reaction

2N2O5 ⟶ 4NO2+O2

Rate = k[N2O5]²

From the question k= 6.2×10-4

[N2O5]= 0.4

Rate = 6.2×10-4[0.4]²= 9.92×10-5M² min-1

Lithium hydroxide is used in alkaline batteries. Calculate the molarity of a solution prepared by dissolving 1.495 moles of LiOH
weeeeeb [17]

Answer:1)1.99 M

Explanation:

Molarity  is given as = moles solute/Liter solution

The solute which is LiOH is already given in moles as 1.495 moles

Given that solution  is  750 mL,  we convert to liters.

Liters of the solution=  mL of the solution   x (1 L/1000 mL)

750 mL x (1 L/1000 mL)

0.75 L

Molarity = moles solute/Liter solution

Molarity = 1.495 moles of LiOH/0.75 L of solution

Molarity = 1.99M

The molarity of this solution is 1.99M (moles per liter).

What is the pH of ammonia? I know the pH of ammonia varies depending on concentration, so what's the pH of pure ammonia?
musickatia [10]
NH3 is a gas at room temperature. Solutions of "ammonia" are made by bubbling NH3 through water, so there's no "pure ammonia" unless you are talking about the gas.

Nitrogen dioxide and water react to form nitric acid and nitrogen monoxide, like this:
posledela

Answer: The value of the equilibrium constant Kc for this reaction is 3.72

Explanation:

Equilibrium concentration of HNO_3 = \frac{15.5g}{63g/mol\times 9.5L}=0.026M

Equilibrium concentration of NO = \frac{16.6g}{30g/mol\times 9.5L}=0.058M

Equilibrium concentration of NO_2 = \frac{22.5g}{46g/mol\times 9.5L}=0.051M

Equilibrium concentration of H_2O = \frac{189.0g}{18g/mol\times 9.5L}=1.10M

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_c  

For the given chemical reaction:

2HNO_3(aq)+NO(g)\rightarrow 3NO_2(g)+H_2O(l)

The expression for K_c is written as:

K_c=\frac{[NO_2]^3\times [H_2O]^1}{[HNO_3]^2\times [NO]^1}

K_c=\frac{(0.051)^3\times (1.10)^1}{(0.026)^2\times (0.058)^1}

K_c=3.72

Thus  the value of the equilibrium constant Kc for this reaction is 3.72
