Max has a group of goldfish in his tank at home. He notices that they are struggling a bit. Max wants to increase their rate of cellular respiration in hopes that it would help them to survive. Which of the following actions would potentially increase the rate of cellular respiration in the goldfish? a. Reducing the amount of food placed in the tank. b. Increasing the amount of carbon dioxide in the tank. c. Increasing the amount of oxygen in the tank d. Reducing the amount of sunlight that hits the tank.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?
