b. what type of heat change is observed in this reaction
c.write word equation for this reaction
d. write chemical equation for this reaction​

Answer 1

Answer:

a.The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products .

b. A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases.

c.-

d.A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). ... Using IUPAC nomenclature, this equation would be read as “methane plus oxygen yields carbon dioxide and water.” This equation indicates that oxygen and CH4 react to form H2O and CO2.
