How many grams of O2 are in 5.0 moles of the oxygen gas?

What would happen if the cell wall in a plant cell just broke like all of them at the same time would it change the color or will it grow faster or will it die what will hapen

Water containing more than 3.0 grains of dissolved solids per gallon is considered to be hard [1 grain (gr) = 64.8 mg]. So, if a kettle contains 18 gal of tap water, which is allowed to evaporate. The solid material left behind has a mass of 1.7 g.

How would you prepare 50.00 ml of an aqueouse solution containing 0.38 m nacl?

When determining the mass of product used or reactant consumed, the number of moles must be determined before comparing two substances because a) moles react. b) atoms have the same mass but moles are different for each substance.

Which of the following nuclei would be the most stable? A. 10 protons, 13 neutrons B. 10 protons, 14 neutrons C. 10 protons, 15 neutrons D. 10 protons, 12 neutrons

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.

To break a chemical bond, energy must be (1) absorbed (2) destroyed (3) produced (4) released
