Answer: The pressure of the gas in atmospheres is 1.76
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 70.0 L
n = number of moles = 
R = gas constant =
T =temperature =
Thus the pressure of the gas in atmospheres is 1.76
Answer:
One plate slides beneath another due to gravitational pull.
Explanation:
Just took this quiz on edgen :)
Answer:
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.
Explanation:
Explanation:
Electrons are negatively charged. So it has a -3 charge.
Answer:
Mn(NO3)3 Molar mass = (54.93) + (3 x 14) + (9 x 16) = 240.93g/mol
Total number of Oxygen atoms in formula = 9
Total mass of oxygen atoms theoretically in the formula = 9x16 = 144g/mol
Oxygen's percentage composition:
(144/240.93) x 100 = 59.7% of the compound is oxygen
