3. Magnesium ribbon reacts with an aqueous solution of copper(II) chloride in a single replacement reaction. Which are the products of the balanced net ionic equation for the reaction

a. Mg2+ (Q4 + 2Cl(aq) + Cu(s)
b. Mgt(aq) + Cl (aq) + Cut(aq)
c. Mg2+ (adj) + Cu(s)
d. Cu(s) + 2Cl (aq)

l dont know l am s sorry

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
