Answer:
Bacteria are vital in keeping nitrogen cycling through the ecosystem, and nitrogen is vital to plant growth. Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system
Explanation:
Answer:
limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
2H2 + 1 O2 ---> 2 H2O
from reaction 2 mol 1 mol
given 3.5 mol 2.5 mol
needed 3.5 mol 1.75 mol
Excess reactant O2, Limiting reactant H2.
Limiting reactant will be used completely.
So, limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
<h3>What amount in moles of hydrogen will be produced?</h3>
The amount in moles of hydrogen produced when the same quantity of electricity is passed through different electrolytes is inversely proportional to the charge on the ions.
The charge on the Lead ion is +2.
The charge on the hydrogen ion is +1.
2 atoms of hydrogen gives one molecule of hydrogen gas.
Hence, equal charge liberates equal amounts in moles of lead and hydrogen gas.
Therefore, 0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
