The answer is
<span>2PbS(s) + 3O2(g) = 2PbO(s) + 2SO2(g)
Your answer is not yet balanced because you have 3 oxygen atoms. it should be balanced by multiplying both side by 2 such as the balanced equation I made. To check it, I will explain why your answer is not yet balanced.
check: (from your equation)
</span> 1-Pb-1
1-S-1
2 -O-3
the difference between the reactant and the product of Oxygen will prove that it is not yet balanced.
If you use 2PbS(s) + 3O2(g) = 2PbO(s) + 2SO2(g), to check it:
2-Pb-2
2-S-2
6 -O-6
then this is now balance
Answer:
H2CO3 represents carbonic acid
Answer:
Empirical Observation, Replicable Experiments, Provisional Results, Objective Approach, and Systematic Observation.
Answer:
<em>The polyoxometalates initially abstract the hydrogen of the alkane to form the alkyl radical and the reduced polyoxometalates. The reduced polyoxometalates subsequently react with nitric acid to produce the oxidized form and nitrogen dioxide.</em>
Explanation:
Answer:
C. the substance in which the solute dissolves
Explanation:
There are two terms in this... the solute and the solvent. The way I learned how to remember this is with a little pirate analogy: The loot (stolen treasure) always goes in the vent. So, the soLUTE goes in the solVENT.
