A student observes a blood sample with a compound microscope that has a 10x ocular month and a 40 X objective lens how much larger do the blood cells appear under the microscope

If this energy were used to vaporize water at 100 ∘C, how much water in liters could be vaporized? Assume that the density of water is 1.0 g/mL. The heat of vaporization of water at 100 ∘C is 40.7 kJ/mol.

In water conservation, chemists spread a thin film of a certain inert material over the surface of water to cut down on the rate of evaporation of water in reservoirs, This technique was pioneered by Benjamin Franklin three centuries ago.

What does the rate of a chemical reaction describe?

Will mark as brainlest What is diffusion? A. The total number of molecules within a volume of gas B. The force created when gas molecules hit their container C. The mixing of gas molecules due to random motion D.

While a certain isotope decays, it emits photons. What kind of decay is happening?

Air is transferred from a 75 L tank where the pressure is 125 psi and the temperture is 288 k to a tire with a volume of 6.1 L and a pressure of 25 psi. What is the new temperture.

Which of the following is a measure of randomness in a system? A) entropy. B) kinetic energy. C) potential energy. D) chemical energy.

What substance can be broken down by chemical means? A) ammonia B) aluminum C) antimony D) argon (Castle learning question)

How the law of conservation of mass could be useful for investigating chemical changes

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.
