Alcohols have higher boiling points than do<span> ethers and alkanes of similar molar masses because the OH group allows </span>alcohol<span> molecules to engage in hydrogen bonding.
Hope this helps</span>
Balance Chemical equation is as follow,
<span> 3 H</span>₂ <span>(g) + N</span>₂ <span>(g) </span>→<span> 2 NH</span>₃ <span>(g)
According to balanced equation, 3 Molecules (3 moles) of Hydrogen reacts with 1 Molecule of N</span>₂ to produce 2 moles (2 Molecules) of NH₃.
Result:
2 Molecules of Ammonia are produced by reacting 3 molecules of Hydrogen and 1 molecule of Nitrogen.
B) experiments that Darwin's original hypotheses
I believe is the right answer :)
Answer:
B) Gas A has twice the molar mass of Gas B.
Explanation:
Partial pressure of a gas is defined as the moles of the gas/ Total moles of the mixture times total pressure. The equation is:
Partial pressure A = Moles A / total moles * Total pressure
From the definition, we can say that the moles of the gas A are twice the moles of B:
2 Moles A = Moles B
As the mass of both gases is the same but the moles of B are twice the moles of A:
The molar mass of A is twice the molar mass of B
Right answer is:
<h3>B) Gas A has twice the molar mass of Gas B.</h3>
