Identify four properties of a substance that will never change

A sample of gas is enclosed in a container of fixed volume. Identify which of the following statements are true. Check all that apply. If the container is heated, the gas particles will lose kinetic energy and temperature will increase.

Which of the following is not an assumption that is made when applying Michaelis-Menten kinetics to an enzyme? Choose one: A. The rate constant of E+Pre-associating to form the ES complex must be considered B.

If a gas in a jar with a leaky seal is heated so that kevin temperature quadruples, what fraction of the moles of gas escape?

How much energy is needed to heat 20.0 grams of water from 25.0°C to 50.0 °C?

What is the change in electrical potential energy during the shrinking process? for your own interest, what was the work needed to change the potential energy? what does the work needed to bring this change?

What is the theoretical yield of silver chloride?

Calculate the cell potential for the galvanic cell in which the reaction Fe (s) + Au 3 + (aq) - ⇀ ↽ - Fe 3 + (aq) + Au (s) occurs at 25 ∘ C, given that [ Fe 3 + ] = 0.00150 M and [ Au 3 + ] = 0.797 M.

Magnesium is lighter than other structural metals, so it is increasingly important in the design of more efficient vehicles.

The relationship between number of particles and pressure is As number of particles increases, pressure increases As number of particles increases, pressure decreases The two are not related

Consider the reaction: Al2S3 + 6 HCl → 2 AlCl3 + 3 H2S The reaction has a 29.1% yield. How many grams of Al2S3 are needed to react with 30.0 moles of HCl? a) The molar mass of Al2S3 is 150.16 grams/mole. b) The molar mass of HCl is 36.46 grams/mole.
