Given 0.500 moles of H₂, how many grams of NH₃ would be produced?
Allisa [31]

Answer:

0.333 mol NH₃

Explanation:

N₂  +  3 H₂  ⇆  2 NH₃

This is the reaction that produces NH₃.  Use the mole ratios to solve.  For every 3 moles of H₂ that are consumed, 2 moles of NH₃ are produced.

(0.500 mol H₂) × (2 mol NH₃/3 mol H₂) = 0.333 mol NH₃

You will produce 0.333 moles of NH₃.

PLEASE HELP!!!<br><br><br>Calculate the PH of an acid solution containing 0.10 M HNO3
Anika [276]

Answer:

The pH would be 1.

Explanation:

The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.

Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.

By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]

                                                                                   =  1
