I dont think with this much amount of information we can solve this...unless its an reversible reaction in that case free energy =0
<span>Crude
oil is mainly made of various polymers with varying sizes of chains. Distillation process separates these elements by their boiling points. The longer
the polymer chain of a particular element in the crude oil, the higher its boiling
point and <span>vice-versa</span></span>
Answer:
1216 mmHg = Partial pressure N₂
Explanation:
In a mixture of n gases, the partial pressure of each compound follows the equation:
Total pressure = Partial pressure n₁ + Partial pressure n₂ + Partial pressure n₃ + Partial pressure n₄ + Partial pressure n₅ + ... + Partial pressure nₙ
In a mixture of O₂, He and N₂, the total pressure = 3040mmHg is defined as:
3040 mmHg = Partial pressure O₂ + Partial pressure He + Partial pressure N₂
Replacing:
3040 mmHg = 304 mmHg + 1520 mmHg + Partial pressure N₂
3040 mmHg = 1824 mmHg + Partial pressure N₂
1216 mmHg = Partial pressure N₂
Answer:
In glucose there are 6 carbon atom, atomic weight carbon is 12, so the molar mass is 72 and the percentage composition of carbon in C6H12O6=(72180)×100%=40% percentage by the mass.
Answer:
3 mol H2 / 1 mol NH3
Explanation:
Mole ratio depicts or shows the relationship between the number of moles of two substances in a chemical reaction. The following chemical equation is given:
N2 + 3H2 → 2NH3
According to the above chemical equation;
- 1 mole of N2 reacts
- 3 moles of H2 reacts
- 2 moles of NH3 is produced
Hence, this means that according to the options provided in this question, the incorrect one is 3 mol H2 / 1 mol NH3 because 2 moles rather than 1 mol of NH3 is involved.
