How many moles of oxygen (O2) are required to completely react with 27.4 mol of H2?

Answers

Answer 1

Answer: This reaction can be written as
H2 + O2 => H2O.
Then, balanced, as
2H2 + O2 = 2H2O

There we see that we need 2 times more mol of H2 than O2. So mol of O2 is 1/2 mol of H2. That is 27.4 mol / 2 = 13.7 mol.

Answer 2

Answer:

Answer:

Explanation:

H2 + O2 => H2O.

Then, balanced, as

2H2 + O2 = 2H2O

There we see that we need 2 times more mol of H2 than O2. So mol of O2 is 1/2 mol of H2. That is 27.4 mol / 2 = 13.7 mol.

Answer : Option A) $H_(2)_((g)) + I_(2)_((s)) ----> 2HI_((g))$ .

Explanation : The reaction of hydrogen gas with iodine in solid phase will react most rapidly at standard conditions.

A rapid chemical reaction is one where reactants react fast with each other to give the products at the standard temperature and pressure conditions.

In the given choices Iodine is highly reactive as it belongs to the halogen group and also atomic hydrogen is very reactive in nature, when both combine it gives hydrogen iodide which is much stable in nature than the reactants.

when one mole of hydrogen reacts with one mole of iodine it produces 2 moles of hydrogen iodide.

$H_(2)_((g)) + I_(2)_((s)) ----> 2HI_((g))$ .

The reaction occurs most rapidly at standard conditions are:
H2(g) + I2(s) 2HI(g)

The reaction that do not occur rapidly at standard conditions are
Cu(s) + S(s) CuS(s)
C6H12O6(s) + 6O2(g) 6CO2(g) + 6H2O(g)
5C2O42-(aq) + 2MnO4-(aq) + 16H+(aq) 10CO2(g) + 2Mn2+(aq) + 2H2O(l)

Ayala is making salad dressing. She mixes oil and vinegar in a blender until a smooth consistency is formed. Explain whether this is a heterogeneous or a homogeneous mixture and why.

Answers

Answer: The mixture formed will be heterogeneous mixture.

Explanation: When we mix oil and vinegar and blend it together to form a smooth mixture, the final mixture will still be heterogeneous in nature.

As we know that vinegar is a solution of acetic acid in water, which is polar in nature and oil is non-polar in nature.

When, we mix polar compound with a non-polar one, the resulting mixture may mix for a certain time, but after a time, we will be able to see the two layers in a mixture.

And heterogeneous mixtures are defined as the mixtures in which there is a distinct physical boundary present between the solutions in a mixture.

Hence, the mixture of oil and vinegar is a heterogeneous mixture.

Sample Response: A homogeneous mixture can only form when one of the substances can dissolve the other one. Oil and water cannot dissolve each other, so they must form a heterogeneous mixture with small particles of vinegar dispersed throughout the oil, yet not dissolved.
