What is the KE of 750 kg car moving at 25 m/s?

Suppose that 3.74 ml of carbon dioxide (C02) accidentally escaped during the experiment, what volume in liters would that be

Density = 7g/ml volume = 10ml

What is formed when atoms of elements combine? A) Compounds B) Elements C) Protons D) Neutrons

What is the heaviest naturally occurring element on earth

Why does air have weight? A. Because everything has weight B. The force of gravity acts on the air molecules' mass C. The pressure of the air molecules colliding with each other gives them weight D. Air fills its entire volume, producing weight

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.
