K + 02 ---> K20
4K + O2 ---> 2K2O
Answer:
main sequence
Explanation:
The main sequence is a band of stars which includes most of them like our sun
<span>2<span>N2</span>+3<span>H2</span>→2N<span>H3
That's the balanced equation. As shown, 4 molecules of N2 would react with 12 molecules of H2. Since not that much H2 molecules exist, then it would serve as the limiting reactant. Therefore:
9 mol H2 * (2NH3 / 3H2) = 6 molecules of ammonia

Answer:
Ability to conduct electricity
Melting point
In order to find the percent yield of a reaction, we need to use the theoretical yield and actual yield into a formula, which is the following:
%yield = (actual yield/theoretical yield)*100
Adding the values from the question in the formula:
%yield = (4.5/10.7)*100
%yield = 42
The percent yield for this reaction will be 42%
