3Al + 3 NH4ClO4 ---> Al2O3 + AlCl3 + 3 NO + 6H20
How many liters of nitrogen monoxide (NO) are formed by completely reacting 50.0 grams of ammonium perchlorate (NH4C104)?

b) nuclear ive learned that in a pedtrodic table

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
