Based on the equation, how many grams of Br2 are required to react completely with 79.2 grams of AlCl3? 2AlCl3 + 3Br2->2AlBr3 + 3Cl2

b. examine and describe cells

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

they are all solids.

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
