B - The reactants are the starting substances and the products are the end substances.
Stella [2.4K]3 years ago
4 0

Answer: Option (b) is the correct answer.

Explanation:

A reaction due to which there occurs a change in the chemical composition of a substance is known as a chemical reaction.

This change in chemical composition occurs when bonds between reactants are broken to form products with new bonds.

Thus, we can conclude that in a chemical reaction products are formed from reactants by the breaking and forming of new bonds.

7. The nuclear model and the solar system model both show atoms with electrons circling around
Keith_Richards [23]

These models are similar because "both the nuclear model and the solar system model have concept of nucleus, electron, positively charged nucleus at center and electrons orbiting around the nucleus".

<u>Explanation:</u>

The points which showcase similarities among both the atomic structure and the composition of the solar system are like the large percentage of the mass centered in the core which is the nucleus or the sun. Attractive forces bring the structure together by application of electromagnetic force or gravitational force.

The existence of the external objects influences the stable state of other surrounding objects as suggested by Pauli theory of exclusion and gravitational disturbance. Overall on the basis of the view only, in both the model their is similarity like atomic model speaks about electrons orbiting the nucleus similar to planets orbiting the sun.

Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide in cells. During this reaction oxygen is given off. A sc
Softa [21]

Answer:

The correct option is A

Explanation:

An independent variable is <u>a variable that is intentionally altered (directly or indirectly) and is not dependent on another variable</u> in the course of an experiment. Unlike the independent variable, the dependent variable depends or is presumed to depend on the altered independent variables.

From the explanation above, it can be deduced that the concentration of the catalase is the independent variable as it was intentionally altered (by using different concentrations) in the course of the experiment. The amount of oxygen given off is the dependent variable here
