Question:Hey. So I need help.I got a question that was like this "Know the name of atleast 1 acid,basis and salt" in chemistry and this is what I found and I want to know if it's right. PS I don't know the names in english so I'll write the formula. Basis: KOH and LiOH Salt: CaSO4 and NH4Cl Acid: HNO3 and HzSO4 Thanks yall! Btw. How can you see if it's a basis,acid or salt? And oh why does substance in group 1,17 and 18 in the periodic system react with eachother?

Answers:yes they are right and i will also give ya the names: basis = Potassium hydroxide(KOH) and Lithium hydroxide (LiOH) salts = Calcium sulphate (CaSO4) and Ammonium chloride (NH4Cl) BTW use NaCl as salt too (sodium chloride) acids = Nitric acid (HNO3) and Sulphuric acid (H2SO4) NOTE!!!! it's H2SO4 and not HzSO4 !!! Hope i helped ya!

physics and chemistry: ratio units (10)

How to interpret and use "ratio units"--units that form ratios, such as "meters/second" or "kilograms/cubic meter" or "newtons/coulomb". Some other common examples of ratio units are watts (joules/second), volts (joules/coloumb), and molarity (moles/liter). The videos should help you to understand and work with concepts such as electric field, electric potential, density, power, concentration, and many other concepts in physics and chemistry that have ratio units. "Ratio units" are important in many other fields--such as economics and finance--as well. These videos are offered on a "pay what you like" basis.
