I think it’s A good luck on the answer if it’s not but I’m pretty sure it’s A .
First, make sure to balance your equation.
3H2(g) + N2(g) ⇄ 2NH3(g)
Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.
Kc = [NH3]^2 / [H2]^3[N2]
Answer:
Explanation:
Hello,
Based on the given chemical reaction, as 31.2 mL of hydrogen are yielded, one computes its moles via the ideal gas equation under the stated conditions as shown below:
Now, since the relationship between hydrogen and magnesium is 1 to 1, one computes its milligrams by following the shown below proportional factor development:
Best regards.
Answer:
1. D/E
2. D/J
3. B/F
4. D or G/I
5. A
Explanation:
This is about sort of concentrations:
1- Molarity
Moles of solute in 1 L of solution
(we can also say, mmoles of solute in 1 mL)
2- Molality
Moles of solute in 1kg of solvent
3. mass %
grams of solute in 100g of solution
4. mole fraction
moles of solute or solvent per moles of solution
5. ppm
mg of solute in 1kg of solution
(we can also say μg of solute in 1 g of solution, or mg solute in 1L of solution)
