[CM.01] Which states of matter appear only in the hydrosphere?

2 answers:

3 0

I will say liquid because the rest all consist of solids and atmosphere also contain gas, but only hydrosphere has liquid.

Answer:

Liquid is the correct answer.

Explanation:

The hydrosphere contains the total amount of water on a planet. The water is on the surface, ground and in the atmosphere. Hydrosphere can be in liquid, gas and solid forms. On earth, the water exists in liquid form in lakes, oceans, and rivers. The frozen part of the water is in the form of an ice cap and icebergs. In hydrosphere, the water moves in a cycle. which leads to the transformation of water from one form to another, it is called the water cycle. The waterfalls in the form of rain and snow and are collected by lakes and ocean. It again evaporates into the atmosphere and the cycle starts again.

Which of the following properly describes the movement of atoms as they represent the states of matter? Atoms making liquids hav

7nadin3 [17]

Answer:

Atoms making liquids have less attraction than solids, but more than gases

Explanation:

The attraction between atoms in different molecules in a solid is very strong due to strong intermolecular forces present in a solid. However, such intermolecular forces are weaker in liquids than in solids.

This implies that the solid has higher intermolecular forces of attraction compared to gases and liquids. Based on the negligible degree of intermolecular forces between them, a gas has the weakest intermolecular forces hence the atom has very minimal interaction between them.

A chemical reaction can theoretically produce 137.5 grams of product, but in actuality 112.9 grams are

Butoxors [25]

<h3>Answer:</h3>

82.11%

<h3>Explanation:</h3>

We are given;

Theoretical mass of the product is 137.5 g
Actual mass of the product is 112.9 g

We are supposed to calculate the percentage yield

We need to know how percentage yield is calculated;
To calculate the percentage yield we get the ratio of the actual mass to theoretical mass and express it as a percentage.

Thus;

% yield = (Actual mass ÷ Experimental mass) × 100%

= (112.9 g ÷ 137.5 g) × 100%

= 82.11%

Therefore, the percentage yield of the product is 82.11 %
