A reaction requires 22.4 L of gas at STP. You have 25.0 L of gas at 101.5 kPa and 373 K. Which statement is true? Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K

A. You will have excess gas for the reaction
B. You do not have enough gas for the reaction
C. Given this information, you cannot tell if you have enough gas for the reaction
D. You will have enough gas for the reaction

the answer is the

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
