Design an experiment that tests the effects of concentration, temperature, and pressure on a chemical reaction that experiences equilibrium

Consider the following balanced equation: 3CuO (s) + 2NH3 (g) → 3H2O (l) + 3Cu (s) + N2 (g) If 70.8 moles of CuO (s) and 40.1 moles of NH3 (g) are allowed to react, what is the theoretical yield of Cu (s) in moles?

A reaction produces 0.863 moles of H2O. How many molecules are produced?

He substance, cocl2, is useful as a humidity indicator because it changes from pale blue to pink as it gains water from moist air. What is its name?

The weighted average atomic mass of an element depends upon the a. relative abundance of protons in the element b. mass and relative abundance of each isotope of that element c. mass and relative abundance of each neutron of that element d.

What part of an atom do we change for isotopes

The Safe Drinking Water Act (SDWA) sets a limit for mercury-a toxin to the central nervous system-at 0.002 mg/L. Water suppliers must periodically test their water to ensure that mercury levels do not exceed 0.002 mg/L.
