A. quantitative

Research data that is presented using descriptive language is said to be quantitative because a research data can also be framed in the form of tables, charts or any other pictorial or diagrammatic form, which can be brief, conclusive or accurate. If the data framed in a descriptive way it's quantity may increase as compared to other formats. The quality of the data also varies according to the way it is presented. Hence, the research data that is presented using descriptive language is said to be quantitative.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
