<u>Given:</u>

Rate of appearance of O2 = 0.250 M/s

Time period = 5.50 s

<u>To determine:</u>

The concentration of O2 formed

<u>Explanation:</u>

2O3 (g) ↔ 3O2 (g)

Rate of appearance of O2 = 1/3 * Δ[O2]/Δt

Based on the given data:

0.250 M/s = 1/3 * [O2]/5.50 s

[O2 ] = 0.250 Ms⁻¹ * 3 * 5.50 s = 4.125 M

Ans: Amount of oxygen formed is 4.13 M

Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left.  If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar.  We want to find the sum of the forces acting on the object.  In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

Explain the term "amphoteric"
Natali5045456 [20]
A substance either an ion or a molecule that can act either an acid or a base depending on a medium is called Amphoteric. Some metals like zinc, tin, copper and aluminium which produce either metal oxides or hydroxides are examples of amphoteric. During the Amphoterism, the metal compound acts either an acid or a base depending on their oxidation state.
