Why does a catalyst work for a long time before it needs replacing?

DedPeter [7]

Because the catalyst is not really part of the reaction. it is something that speed up a reaction by lowering the energy need for the reaction to take place. however, in the end the catalyst is brought back to its initial state. that's why it is long lasting

A cylinder contains nitrogen and oxygen under 4.015 atm pressure. The partial pressure of N2 is 2.907 atm. What is the partial p

Aleksandr-060686 [28]

Answer: The partial pressure of the water vapor is 1.108 atm

Explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

$p_{total}=p_A+p_B$

Thus $p_{total}=p_{N_2}+p_{H_2O}$

Given: $p_{total}$ =4.015 atm

$p_{N_2}$ = 2.907 atm

$p_{H_2O}$ = ?

Thus $4.015=2.907+p_{H_2O}$

$p_{H_2O}=1.108atm$

Thus the partial pressure of the water vapor is 1.108 atm

What’s the radius of a nucleus

Rudiy27

Answer:

Explanation:

It is found that nuclear radii range from 1-10 ´ 10^-15 m. This radius is much smaller than that of the atom, which is typically 10^-10 m. Thus, the nucleus occupies an extremely small volume inside the atom. The nuclei of some atoms are spherical, while others are stretched or flattened into deformed shapes.
