b It was a compound.

Explanation:

A chemical reaction was used to separate a sample into its components. What conclusion about the sample can be formed based on the technique used?

a It was a pure substance.  NO. If the pure substance is a compound, this option could be. However, if the pure substance is a simple substance, it could not be separated into its components.

b It was a compound. YES. Compounds can be separated into pure substances using chemical reactions. For instance, H₂O → H₂ + 1/2 O₂

c It was a heterogeneous mixture.  NO. Heterogeneous mixtures can be separated into homogeneous mixtures using physical processes such as sieving, filtration, etc.

d It was a homogeneous mixture. NO. Homogeneous mixtures can be separated into pure substances using physical processes such as distillation, chromatography, etc.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
