Explain the following terms- (a) Balanced equation (b) Catalyst (c) Word equation (d) Radical (e) Radioactivity
Answers
Answer:
a) A balanced question is one that has a question stem that presents the respondent with both (all reasonably plausible) sides of an issue.
b) Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst. Catalysts are not consumed in the catalyzed reaction but can act repeatedly. Often only very small amounts of catalyst are required
c) A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae.
d) a person who wants great social or political change
e) Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.
