Help I need this done for today :3 A 100N load is lifted to a height of 5 m in 30 seconds. Calculate the power. (Hint-you must first solve for work) Make sure to use the correct unit labels.

1. calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. iqnore the thermal mass of th sodium bicarbonate. note: it takes about 4.2 joules () to change 1.0 gram (1.0ml) of water 1.0 c

Based on the equation and the information in the table, what is the enthalpy of the reaction?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.
