The equation for the reaction is given below:

2H2 + O2 —> 2H2O

from the equation,

2moles of H2 required 1mole of O2.

Therefore, 6moles of H2 will require = 6/2 = 3moles of O2

Answer:F. 3 moles of oxygen.

Explanation: The solution is as follows:

The mole ratio between H2 and O2 is 2:1 so the stoichiometric solution will be:

6 moles H2 x 1 mole O2 / 2 moles H2

= 3 moles O2

Why is it better to measure the percent change in mass<br> ratherthan just using the change in mass?
never [62]

Answer: The result is presented in proportion which gives a clearer understanding and accurate result.

Explanation: Percentage change in mass is the proportion of the initial mass of a substance changed after sometime. The results is presented as a percentage making it more accurate and can help to give future reference to weight calculations.

Change is Mass is the mass of a substance left after sometime mostly given in grams. It is not as accurate as percentage change in mass. It is generally better to show results in percentage change in mass as it gives a better understanding of what mass of a substance was lost after a given period or after application of energy like Heat or increased temperature.

An atom has a mass number of 30 and 16 neutrons. What is the atomic number of this atom?
Lana71 [14]
The mass number is the number of protons plus the number of neutrons. Since there are 16 neutrons, there are 14 protons. This also corresponds to the atomic number, so this atom's atomic number is 14 which is also Silicon
