IgorC [24]

Answer:

0.187 mol

Explanation:

A solution is created by dissolving 10.0 grams of ammonium chloride in enough water to make 315 mL of solution.

The formula of ammonium chloride is NH₄Cl and its molar mass is 53.49 g/mol. We can use this information to calculate the moles of ammonium chloride associated with 10.0 grams.

10.0 g × (1 mol/53.49 g) = 0.187 mol

2NO (g) + O2 (g) →2NO2 (g) At equilibrium [NO] = 2.4 × 10 -3 M, [O2] = 1.4 × 10 -4 M, and [NO2] = 0.95 M.

Answer:

K=1.12x10^9

Explanation:

Hello there!

Unfortunately, the question is not given in the question; however, it is possible for us to compute the equilibrium constant as the problem is providing the concentrations at equilibrium. Thus, we first set up the equilibrium expression as products/reactants:

K=\frac{[NO_2]^2}{[NO]^2[O_2]}

Then, we plug in the concentrations at equilibrium to obtain the equilibrium constant as follows:

K=\frac{(0.95)^2}{(0.0024)^2(0.00014)}\\\\K=1.12x10^9

In addition, we can infer this is a reaction that predominantly tends to the product (NO2) as K>>>>1.

Best regards!

How many grams of potassium chlorate are needed to saturate 100g of water at 70 celsius? Group of answer choices 48 g 100 g 34 g
marissa [1.9K]

Answer:

34g of potassium chlorate.

Explanation:

A saturated solution is a solution that, under a temperature, has the maximum amount of solute possible. The maximum amount that a solvent can dissolve of a solute is called <em>solubility.</em>

<em> </em>

The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.

That means, to saturate 100g of water at 70°C you need yo add:

<h3>34g of potassium chlorate.</h3>
