Question

1. what methods can be used to organize quantitative and qualitative data?

graphs
personal opinions
tables
charts
essays

1. what factors affect the rate of a chemical reaction or dissolving?

radiation
reflection
refraction
conduction
convection

Explanation:

For the first question, graphs, tables, and charts are common tools for organizing both quantitative and qualitative data as they present data in an orderly and visual - izable way. Personal opinions are subjective and not a method of organizing data, and essays are more for presenting analysis or arguments rather than just organizing data.
For the second question, radiation can affect the rate of a chemical reaction or dissolving by providing energy or ionizing substances. Reflection, refraction, conduction, and convection are not factors that directly affect the rate of a chemical reaction or dissolving in the same way as radiation. Reflection and refraction are related to light - wave behavior, while conduction and convection are heat - transfer mechanisms not directly tied to reaction/dissolving rates in the same context.

Answer:

1. A. Graphs, C. Tables, D. Charts
2. A. Radiation
