Answer:
The number is mostly related to the mass or the weight of the element.
Explanation:
Something created for using science for use by society. Hence, option A is correct.
<h3>What is science?</h3>
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.
Technology is the use of science to provide human problem. It can be in the form of a machine, tool or equipment. As long as it involves applying a scientific process, it's technology.
Example of technology is a computer. It's used to store and process data in a faster way. Old technology also included Hammer, Saw, Grinding Machines etc.
Hence, option A is correct.

The lysis reaction with the formation of two different gases, and the synthesis reaction with the reaction of hydrogen and oxygen support that water is a compound and not an element.
<h3>What is electrolysis?</h3>
The electrolysis is the analytical process for the separation or the deposition of the element in the presence of the electric field.
The passing of electric current through water results in the release of two types of gases. Thus, it can be said that water lysis or breakdown forms the release of two elements hydrogen and oxygen supporting the fact that water is a compound and not an element.
The production of water is found to be formed with the reaction of hydrogen with oxygen. Thus it supports that water is a compound and, not an element.

To balance a chemical equation you must pay attention that the algebraic equation has the same number of element atoms in reactant and the product.
A chemical equation is a term to refer to the symbolic description of a chemical reaction, that is, the written representation of symbols. For example:
The balance of an equation can be related to the law of conservation of matter, that is, the number of atoms of each element in the reactants is in the result.
