Which part of a plant cell is responsible for converting light energy into chemical energy?

How does an increase in temperature affect a chemical reaction?

When sedimentary rock is exposed to heat and pressure what dose it change to

A spoon of salt is added to water. Which of these will increase how fast the salt dissolves? Check all of the boxes that apply.

Indicate whether each statement is true or false. Sort these statements into the proper categories. A) NaCl dissolves in water but not in benzene (C6zH6) because benzene is denser than water.

What is an example of making a qualified observation

With respect to composition, how is the compound made from hydrogen and oxygen different from mixtures of these two elements?

How should scientist respond when new evidence that challenges current is presented?

Consider the following reaction, equilibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium pressure of H2. D2 (g) + H2 (g) ⇌ 2 HD (g) Kp = 1.80 P (D2) eq = 1.1 * 10-3 atm P (HD) eq = 2.7 * 10-3 atm

Find δe for the change in state of 1.0 molh2o (l) at 79 ∘c to h2o (g) at 116 ∘c. the heat capacity of h2o (l) = 75.3 j/molk, heat capacity of h2o (g) = 25.0 j/molk, and the heat of vaporization of h2o is 40.7*103j/mol at 100 ∘c.
