Answer: 4000000000
because 20X200000000=4000000000
48.3 g AgNO3 / 169.9 g/mol = 0.284 moles AgNO3
0.284 mol AgNO3 X (1 mol Ag2CrO4/2 mol AgNO3) = 0.142 mol Ag2CrO4
0.142 mol Ag2CrO4 X 331.7 g/mol = 47.1 g Ag2CrO4
True!
Energy released by system is absorbed by surroundings.
Answer:
Neutron does not contain any charge because the charge of the quarks that made up the neutron balances each other out.
