Experimental
Wewaii [24]

Answer:

Error.

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

Experimental error is a factor that can arise from incorrect use of measuring tools or malfunctioning equipment such as thermometer, barometer, multimeter, voltmeter, ammeter, vernier caliper, etc. This error usually causes test results to be inaccurate, incorrect and as such leading to wrong experimental conclusions.

Also, one common example of an experimental error is the error due to parallax.

Which of these accurately describes the reactants of a reaction?
oksian1 [2.3K]

Option (C) is the correct answer.

In the chemical reaction, reactants are the starting elements or compounds which will chemically react and will form the products. Reactants are only present on the left hand side of the reaction and products are present on the right hand side of the reaction.

Reactants present in the reaction is completely used up in the reaction to form products implies no traces of reactants will be present in the product side.

For example:

2H_{2}+O_{2}\rightarrow 2H_{2}O

Here, hydrogen and oxygen are the reactants whereas water is the product (new substance). Hydrogen reacts with oxygen and form water i.e. hydrogen and oxygen is completely used up in the reaction to form new substance i.e. water.

Hence, substances that are used up in a reaction is known as reactants of the reaction.
