Calculate the standard heat of the neutralization reaction between dilute hydrochloric acid and dilute potassium hydroxide, given that the heat of solution of potassium hydroxide is -54.01 kj/mol, the heat of formation of potassium hydroxide is -426.84 kj/mol, the heat of solution of potassium chloride is 18.426 kj/mol, and the heat of formation of potassium chloride is -436.584 kj/mol. number ah," = kj/mol b) calculate the heat of reaction for the reaction of gaseous hcl and solid koh to form liquid water and solid kci. number añ° = 10 kj/mol

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
