Answer:
5 moles of H2
Explanation:
2 mol HCl * x mol H2 = 10 mol HCl
x=5
Check work:
5 mol H2 * 2 mol HCl/1 mol H2 = 10 mol HCl
Answer:
The coefficient for Al(s) is 2.
Explanation:
__ Al(s) __ O2(g) --> __ Al2O3(s)
__ Al(s) __ O2(g) --> 1 Al2O3(s)
1 Al(s) __ O2(g) --> 1 Al2O3(s)
1 Al(s) + 1.5 O2(g) --> 1 Al2O3(s) [Use a fraction to make it balance]
2 Al(s) + 3 O2(g) --> 2 Al2O3(s) [Convert the 1.5 fraction to a whole number by multiplying all coefficients by 2]
The objects that could hit the atoms in the model shown are neutrons.
<h3>What is a chain reaction?</h3>
A chain reaction is a reaction that is able to sustain itself. In this case, when the neutrons collide with the fissile nucleus, more neutrons are produced which collides with more fissile nuclei thereby sustaining the reaction.
Thus, the objects that could hit the atoms in the model shown are neutrons.
