The correct answer is B. Decreases

Explanation:

Gravitational force is a natural force that occurs as objects composed of mass attract others. This applies to planets, stars, and other massive objects but also objects with less mass. Additionally, the gravitational force is described through the formula F (Gravitational Force) = G (Gravitational constant) M m (mass of the two objects) / r2 (distance).

This shows the distance is key for gravitational force; indeed, as distance increases gravitational force decreases and vice versa. This explains why the gravitational force has a great effect on all elements in the Earth, but other planets do not have this effect as the gravitational force exerted by these objects is weak due to the great distance. Thus, as the distance between two objects increases, the gravitational force decreases.

There are eight consitutional isomers with the molecular formula C4H11N.
Dmitriy789 [7]

Answer:

See figure 1

Explanation:

We have to remember that in the isomer structures we have to <u>change the structure</u> but we have to maintain the <u>same formula</u>, in this case C_4H_1_1N.

In the formula, we have 1 nitrogen atom. Therefore we will have as a main functional group the <u>amine group</u>.

In the amines, we have different types of amines. Depending on the number of carbons bonded to the "N" atom. In the <em>primary amines</em>, we have only 1 C-H. In the <em>secondary amines</em>, we have two C-N bonds and in the <em>tertiary amines</em>, we have three C-N bonds.

With this in mind, we can have:

-) <u>Primary amines:</u>

1) n-butyl amine

2) sec-butyl amine including 2 optical isomers

3) isobutyl amine

4) tert-butyl amine

-) <u>Secondary amines:</u>

5) N-methyl n-propyl amine

6) N-methyl isopropyl amine

7) N, N-diethyl amine

-) <u>Tertiary amines:</u>

8) N-ethyl N, N-dimethyl amine

See figure 1

Hydrogen gas and solid gold(III) sulfide are reacted. Pure solid gold metal is formed and gaseous hydrogen sulfide is released.
alexdok [17]

The reactants of the reaction will be solid gold (III) sulfide and hydrogen gas, while the products will be pure solid gold and hydrogen sulfide gas.

<h3>Chemical reactions</h3>

Reactants react together during reactions to arrive at products.

In this case, solid gold (III) sulfide and hydrogen gas react according to the following equation:

Au_2S_3(s) + 3 H_2 (g)-- > 2 Au(s) + 3H_2S(g)

Reactants = solid gold (III) sulfide, hydrogen gas

Products: pure solid gold, hydrogen sulfide gas

The nucleus of an atom of K-42 contains
mafiozo [28]
The atomic number is the number of protons, while the atomic mass is the number of protons added to the number of neutrons. By definition, potassium (K) has atomic number 19, so it should have 19 protons. If it has a mass of 42, then the number of neutrons is 42 - 19 = 23 neutrons. This is choice (1).
