Consider the process a(l) → a(g) 73°c 161°c, which is carried out at constant pressure. the total δs for this process is known to be 75.0 j·k−1·mol−1. for a(l) and a(g), the cp values are 75.0 j·k−1·mol−1 and 29.0 j·k−1·mol−1, respectively, and are not dependent on temperature. calculate δhvaporization for a(l) at 125°c (its boiling point).

Amonoprotic acid is an acid that donates a single proton to the solution. suppose you have 0.140 g of a monoprotic acid dissolved in 35.0 ml of water. this solution is then neutralized with 14.5 ml of 0.110 m naoh. what is the molar mass of the acid?

Sarah wants to know where in her garden chamomile would grow the best. she thinks chamomile will grow best in the corner of the garden that gets the most sunlight. to test her hypothesis, she decides to plant several groups of chamomile in her garden as an experiment. which of the following variables will sarah need to measure to know which group of plants grew best? a. the location of the plants b. the type of plants c. the height of the plants d. the amount of water she gives the plants

Avariable that is not being directly tested during an experiment should be
