The answer is that the pilot was tired of life and committed suicide with hundreds of passengers.
Answer:
moles gaseous reactants will be doubled
Explanation:
Avogadro's law about ideal gas can be presented as PV=nRT where P is pressure, V is volume, n is the number of molecules, R is constant, and T is temperature.
The question asks how many molecules of gas reactant (n) so we can tweak the formula into n=...
PV=nRT
n=PV/RT
Pressure, constant and temperature are the same so we can remove it from the equation.
n= V
The volume is directly proportional to the number of molecules. If the volume is doubled then (V2= 2*V1), then the number of the molecule(n) needed will be doubled too.
Answer:
A. ions with opposite charges
Explanation:
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
Answer:
D
Explanation:
gas are well separated with no regular arrangement and spreaded all over. liquid are close together with no regular arrangement and slightly spreaded. solid are tightly packed, usually in a regular pattern and not spreaded at all.
Moles = mass(g) / ar
Reconfigure the eqn to
Mass(g) = Moles × ar
Imput the info you have and the ar of Mn and you should be able to get your ans. Sorry, i dont have a calculator with me.
