Complete end balance the reaction :copper plus hydrobromic acid

Chemistry
1 answer:
Reika [66]2 years ago
5 0

Answer:

The correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2

Explanation:

Copper (Cu) and hydrobromic acid (HBr), which is a dissolved form of hydrogen bromide in the water, react and produce hydrogen dibromidocuprate (I) and hydrogen molecules.

The complete and balanced equation is -

2Cu + 4HBr → 2H[CuBr2] + H2

This reaction takes place in the medium of ester. Copper is in the suspension form in this reaction.

Thus, the correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2

Please help me and explanation would be really awesome thank you!
valentina_108 [34]

Answer:

So the answer would be 10 moles

Explanation:

1) Start with the molecular formula for water: H_{2} O!

2) If there are 10 moles of water use a mole ratio to calculate the moles of oxygen it would produce.

(This question is... interesting... since they chose an element that is diatomic in free state so It could TECHNICALLY be two answers, moles of O or moles of O_{2})

The mole ratio is 1 moles of H_{2}O to 1 moles of O. This is because the coefficient for oxygen in water is simple 1, so the ratio is 1:1.

3) that means if 10 moles of water decompose, they decompose into 10 moles of H_{2} and 10 moles of O.

Extra:

About what I was saying before about the question being slightly interesting:

10 moles of pure oxygen is produced but free state oxygen exists as O_{2} so it could possibly be 10 OR 5! However, notice it says elements. This leads me to believe the answer is 10 (monatomic oxygen) instead of 5 (free state/diatomic oxygen).

I hope this helps!

The stronger the intermolecular forces, the _______the energy needed to separate the molecules, the ____________the boiling poin
slamgirl [31]

Answer:

higher, higher

Explanation:

It takes more energy to rip apart stronger bonds (that's mostly just common sense there). The boiling point increases because it would take more energy to get the molecules to go from a stuck together liquid, to separating in a gaseous form.
