<h2>Answer:</h2>

In <u>Combination reaction</u>, two or more elements combined to form one compound of different properties.

  • C(s) + O2(g) ⇢ CO2(g).
  • H2(g) + O2(g) ⇢ H20(l).

In <u>Displacement reation</u>, the high reactive element displaces the low reactive element and formed compound of different properties.

  • Fe(s) + CuSo4(aq) ⇢ FeSo4(aq) + Cu(s).
  • AgNO3(aq) + Cu(s) ⇢ CuNO3(aq) + Ag(s).

15 grams of HCl should theoretically produce 0.42 grams of H2. The reaction actually produced 0.15 grams of H2. What is the perc
Helen [10]

Answer:

35.7%

Explanation:

The percent yield is calculated by the formula:

<em>[(actual yield) / (theoretical yield)] * 100</em>

In this case, the actual yield is 0.15 grams, and the theoretical yield is 0.42 grams. So, putting these values into the equation, we have:

\frac{0.15}{0.42} *100=0.357*100=35.7

Thus, the percent yield of H_2 is 35.7%.

Hope this helps!
