Answer:

A 400,000 kg object and a 100,000,000kg object

Explanation:

The objects with the most mass between them will have the greatest gravitational attraction.

This is why the last option is the right choice.

The reason for this is based on the Newton's law of universal gravitation which states that:

"the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

So, the more the mass, the greater the gravitational attraction between two bodies.

Two reactions and their equilibrium constants are given. A + 2 B − ⇀ ↽ − 2 C K 1 = 2.79 2 C − ⇀ ↽ − D K 2 = 0.186 Calculate the

Answer:

K=1.93

Explanation:

Given reactions are:

A +2B ⇄ 2C K1=2.79

2C ⇄ D K2=0.186

D⇄ A+ 2B K=?

If we reverse the reaction then the euillibrium constant also become reciprocal of original value:

3rd reaction is a combination of reciprocal of 1st and 2nd reaction

2C⇄A +2B 1/K1;........................1

D ⇄ 2C 1/K2; ..............................2

On adding 1 and 2

D ⇄A +2B $K=\frac{1}{K1} \times\frac{1}{K2};$

$K=\frac{1}{2.79} \times\frac{1}{0.186};$

K=1.93
