B) are often quite different from each other
Think, do you think a lung cell looks and does the same as an eye cell? No, they do not.
Answer:
113 g
Explanation:
Zn + 2 MnO2 + H2O → Zn(OH)2 + Mn2O3
(46.8 g Zn) / (65.3820 g Zn/mol) x (1 mol Mn2O3 / 1 mol Zn) x
(157.87438 g Mn2O3/mol) = 113 g Mn2O3
Your answer is (4) methanoic acid, more commonly known as the formic acid. It is a weak electrolyte that dissolves into H^+ and COOH^-
Work = Force * distance (aka Weight * height lifted)
Work to lift 1 brick:
W = mgh = (4 kg)(9.8 m/s²)(15 m) = 588 J
Work to lift 520 bricks:
W = 520(588 J) = 305,760 J
