Negatively-charged ions are anions, formed from nonmetallic elements like OXYGEN and sulfur.
Answer:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds. ... The ratio of the elements in a compound are always constant. (Water is always 11 % Hydrogen and 89 % oxygen).
Explanation:
Answer:
See below
Explanation:
Use Ideal Gas Law
PV = n RT using R = .082057366 l-atm/k-mol
T must be in Kelvin
solve for 'n'
.92 * 1.6 = n * .082057366 * 287
n = .0625 moles
then the mole weight: .0625 * x = .314
x = mole weight = 5.025 gm
"Systems with either very <u>low pressures or high temperatures</u> enable real gases to be estimated as “ideal.” "
