Answer:
Explanation:
Hello,
In this case, given that the mass of the product is 0.534 g, we can infer that the percent composition of tin is:
Therefore, the percent composition of oxygen is 6.4% for a 100% in total. Thus, with such percents we compute the moles of each element in the oxide:
In such a way, for finding the smallest whole number we divide the moles of both tin and oxygen by the moles of oxygen as the smallest moles:
Therefore, the empirical formula is:
Best regards.
The answers would be organisms in water, water, and air.
Answer:
Check explanation
Explanation:
During the Electron Transport System occur in the mitochondrial membrane, oxygen in this reaction is been reduced to water and ATPs are being produced.
The quinone form or the oxidized form of Flavin Adenine Dinucleotide(FAD) is the FADH2. While Nicotinamide adenine dinucleotide is the acronym for NADH. NADH is a good donating substance/agent.
It has been observed that FADH2 produce two(2) ATP while NADH produces three(3) ATP. The reason for this observation is that the production of electron in the FADH2 is at the lower enegy level. Because of this it can not transfer its electron to the first complex .
While;
NADH is at the higher energy level and it can directly transfer its electron to the first complex.
Answer: The actual yield of 
is 60.0 g
Explanation:-
The balanced chemical reaction :
Mass of 
=
According to stoichiometry:
1 mole of gives = 1 mole of
1.51 moles of gives =
moles of
Theoretical yield of 
Percent yield of = 
Thus the actual yield of is 60.0 g
Answer:
5.63 mol.
Explanation:
- The balanced chemical equation between NO₂ and H₂O is:
<em>3NO₂(s) + H₂O(l) → 2HNO₃(aq) + NO(g),
</em>
It is clear that 3 mol of NO₂ reacts with 1 mol of H₂O to produce 2 mol of HNO₃ and 1 mol of NO.
<em>Water is present as an excess reactant and NO₂ is limiting reactant.</em>
<em></em>
- To find the no. of moles of HNO₃ produced:
3 mol of NO₂ produces → 2 mol of HNO₃, from stichiometry.
8.44 mol of NO₂ produces → ??? mol of HNO₃.
∴ The no. of moles of HNO₃ are formed = (8.44 mol)(2 mol)/(3 mol) = 5.63 mol.
