A piece of potassium metal is added to a sample of zinc chloride. If you started with 3.8 g of potassium and 8.4 g of zinc chloride, determine the limiting reactant, and the amount of metal produced

Explanation:

3.8g              8.4g

2K     +          ZnCl2      =  2 KCl     +     Zn

2 mol             1 mol                                 1 mol

39g/mol        135g/mol

Need 2 mol K for 1 mol ZnCl2

3.8g K/39g/mol = .97 mol K       8.4g ZnCl2/135g/mol  =  0.062 mol ZnCl2

0.062 mol ZnCl2 X 2 mol K/1 mol ZnCl2 =0.124 mol K

ZnCl2 limiting

0.062 mol ZnCl2 = 0.062 mol Zn

0.062 mol Zn x 65 g/mol =   4.0 g Zn

sry but any answer choices

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
