Answer:
C₃H₈(g) + 6 H₂O(g) ⇒ + 10 H₂(g) + 3 CO₂(g)
Explanation:
Propane can be turned into hydrogen by the two-step reforming process.
In the first step, propane and water react to form carbon monoxide and hydrogen. The balanced chemical equation is:
C₃H₈(g) + 3 H₂O(g) ⇒ 3 CO(g) + 7 H₂(g)
In the second step, carbon monoxide and water react to form hydrogen and carbon dioxide. The balanced chemical equation is:
CO(g) + H₂O(g) ⇒ H₂(g) + CO₂(g)
In order to get the net chemical equation for the overall process, we have to multiply the second step by 3 and add it to the first step. Then, we cancel what is repeated.
C₃H₈(g) + 3 H₂O(g) + 3 CO(g) + 3 H₂O(g) ⇒ 3 CO(g) + 7 H₂(g) + 3 H₂(g) + 3 CO₂(g)
C₃H₈(g) + 6 H₂O(g) ⇒ + 10 H₂(g) + 3 CO₂(g)
Answer:
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring.
Answer:
Balanced reaction: 
S is oxidized and N is reduced.
is the oxidizing agent and ZnS is the reducing agent.
Explanation:
Reaction: 
Oxidation: 
Balance charge: 
...............(1)
Reduction: 
Balance H and O in acidic medium : 
Balance charge: 
...............(2)
[
Equation-(1)] + [ 
Equation-(2)]:
Oxidation number of S increases from (-2) to (0) for the conversion of ZnS to S. Therefore S is oxidized.
Oxidation number of N decreases from (+5) to (+2) for the conversion of to NO. Therefore N is reduced.
consumes electron from ZnS. Therefore is the oxidizing agent and ZnS is the reducing agent.
Answer: 3.13 g
Explanation:
Radioactive decay follows first order kinetics.
Half-life of uranium-232 = 68.8 years
N = amount left after time t
= initial amount
= rate constant
t= time
= 100 g, t= 344 years, 
N=3.13g
