Answer: the momentum is 6 Kgm/s
Explanation:
M= 5 kg
V= 1.2 m/s
Momentum = MV = 5 x 1.2 = 6 Kgm/s

PbO2 (s) + 4 HCl (aq) → PbCl2 (s) + Cl2 (g) + 2 H2O (l)
This is an oxidation-reduction (redox) reaction:
PbIV + 2 e- → PbII
(reduction)
2 Cl-I - 2 e- → 2 Cl0
(oxidation)
PbO2 is an oxidizing agent, HCl is a reducing agent.
Answer:
4 moles
Explanation:
the equation is N2 + H2 => NH3
We have 6 moles of hydrogen, so H2 * 6 is 12 Hydrogen molecules
Nitrogen is in excess so not limiting, and ammonia requires 3 hydrogen molecules, so 12/3 =4 moles
Answer: 2.19x10²⁴ atoms CH4
Explanation: solution attached:
3.64 moles CH4 x 6.022x10²³ atoms CH4 / 1 mole CH4
= 2.19x10²⁴ atoms CH4
