Proton-proton chain reaction is: The destruction of energy due to lost atoms. The creation of energy through the process of nuclear fusion. The sharing of energy through radioactive zone. The decline of energy due to a solar eclipse.

If you combine 320.0 ml of water at 25.00 °c and 120.0 ml of water at 95.00 °c, what is the final temperature of the mixture? use 1.00 g/ml as the density of water.

Imagine you have two containers of gas, one lable of gas A and one lable of gas b. gas A has average speed of 700m/s and gas B has an average speed of 1100m/s. both container are being held at the same temperature.

Two different proteins X and Y are dissolved in aqueous solution at 37 ∘C. The proteins bind in a 1:1 ratio to form XY. A solution that is initially 1.00 mM in each protein is allowed to reach equilibrium. At equilibrium, 0.23 mM of free X and 0.

What are explosives made up of

For the equilibrium reaction 2NH3 (g) + 22 kJ ↔ N2 (g) + 3H2 (g), which of the following changes would result in the formation of more N2 and H2 at equilibrium?

When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. this concept is called conservation of mass.

The elements on the Periodic Table are arranged in order of increasing (1) atomic mass (2) atomic number (3) first ionization energy (4) selected oxidation state
