Achemical 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. b it was a compound. c it was a heterogeneous mixture. d it was a homogeneous mixture

Answer;

B It was a compound

Explanation;

A pure chemical compound is a chemical substance that is composed of a particular set of molecules or ions that are chemically bonded. Two or more elements combined into one substance through a chemical reaction, such as water, form a chemical compound.

A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice.  Unlike elements compounds can be broken down in chemical means.

answer; natural resources;

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
