fomenos

Answer: CaCO_3 is a reactant; it is present before the reaction occurs.

Explanation:

In a chemical reaction the chemical formulas written before the arrow are described as reactants as they react together to form products which are written after the arrow.

CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O

Thus CaCO_3 and HCl are reactants here whereas CO_2, CaCl_2 and H_2O are products.

Information about how a chemical reacts under high pressure can be found in the ""reactivity"" section of a msds. True or false?
dezoksy [38]

Information about how a chemical reacts under high pressure can be found in the "reactivity" section of a MSDS: True.

<h3>What is MSDS?</h3>

MSDS is an abbreviation for Material Safety Data Sheet and it can be defined as a text-based document which is designed and developed to provide more information with respect to the chemical and physical properties of an equipment, chemical compound, or substance, based on the following:

  • Reactivity
  • Flammability
  • Temperature
  • Radioactivity

In this context, we can infer and logically deduce that it is true that the information about how a chemical react would under high pressure can be found in the "reactivity" section of a Material Safety Data Sheet (MSDS).
