This is an incomplete question, here is a complete question.

Which of the three gases will have the highest average kinetic energy at a given temperature?

A) HBr

B) NO₂

C) C₂H₆

Answer : All three gases will have the same average kinetic energy at a given temperature.

Explanation :

The formula for average kinetic energy is:

$K.E=\frac{3}{2}kT$

where,

K.E = average kinetic energy

k = Boltzmann’s constant

T = temperature

As we know that, average kinetic energy depends only on the temperature.

As the temperature of the all three gases are same. So, the all three gases will have the same average kinetic energy.

How many atoms are in 0.500mol of calcium?

creativ13 [48]

Answer:

3.01×10²³ atoms of calcium

Explanation:

number of moles = number of atoms/Avogadro's constant

n = N/NA

N = n×NA = 0.500 mol×6.02×10²³ mol^-1

N = 3.01×10²³ atoms of calcium

In the reaction C5H8+____ O2= 8H2O+5CO2

Romashka-Z-Leto [24]

I don't think that the whole question is posted here, but if you are looking for a way to balance this equation, I may have the answer. I believe the balanced equation is C5H8+9O2=4H2O+5CO2. If you need the reaction type, the answer is combustion. Hope this helps you.

What compound is formed when 2,2-dimethyloxirane (2-methyl-1,2-epoxypropane) is treated with ethanol containing sulfuric acid

vladimir1956 [14]

Answer:

2-ethoxy-2-methylpropan-1-ol

Explanation:

On this reaction, we have an "epoxide" (2-methyl-1,2-epoxypropane). Additionally, we have acid medium (due to the sulfuric acid $H_2SO_4$ ). The acid medium will produce the hydronium ion ( $H^+$ ). This ion would be attacked by the oxygen of the epoxide. Then a carbocation would be produced, in this case, the most stable carbocation is the tertiary one. Then an ethanol molecule acts as a nucleophile and will attack the carbocation. Finally, a deprotonation step takes place to produce 2-ethoxy-2-methylpropan-1-ol.

See figure 1
