multiple - choice question\nthe temperature increases due to\ngases were produced in abundance.\nthe higher temperature of the sodium hydroxide that was added.\nthe breaking and forming of new chemical bonds between the substances in the combined solutions.\na precipitate was formed.
Answer
Brief Explanations:
In a chemical reaction, temperature changes occur due to energy - related processes. When new chemical bonds are formed and old ones are broken in a reaction between substances in combined solutions, heat can be released or absorbed. Exothermic reactions release heat, causing a temperature increase. The formation of gases or a precipitate doesn't directly cause a temperature increase in the way described here, and the temperature of the added sodium hydroxide is not the main reason for the overall temperature increase in a reaction context.
Answer:
the breaking and forming of new chemical bonds between the substances in the combined solutions.
