<h3>Answer:</h3>

Weight

<h3>Explanation:</h3>

The weight of an object is different on every planet in the solar system.
Weight is the gravitational pull of an object towards the surface of a planet.
It is measured in Newtons, using a spring balance .
Weight changes from one place to another depending on the gravitational acceleration of a surface.
For example, the weight of an object on the surface of the earth is different from the weight of the same object on the surface of the moon.
Mass of an object, on the other hand, remains constant and is the same on every planet in the solar system.

DerKrebs [107]

Answer:

The answer to your question is the third choice.

Explanation:

CaCO₃ ⇒ CaO + CO₂

Check if the reaction is balanced or unbalanced

Reactants Elements Products

1 Calcium 1

1 Carbon 1

3 Oxygen 3

As the number of atoms in the reactant is the same that the number of atoms in the products we conclude that the reaction is balanced.

So the correct answer is balanced because the total number of oxygen atoms is 3.

Vikki [24]

Answer:

A neutralization reaction between an acid and a metal hydroxide produces salt and water.

Explanation:

In a neutralization reaction, an acid and a base are combined according to the following example (hydrochloric acid and sodium hydroxide):
