How many grams of silver nitrate are needed when 82.17 grams of cobalt (III) nitrate are produced according to the following reaction? _CoBr3 + _Ag(NO3) -> _AgBr + _Co(NO3)3

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Which of the following is always a reactant in a combustion reaction? oxygen nitrogen hydrogen carbon
