3. Nickel replaces silver from a solution of silver nitrate according to the following reaction: 1 Ni + 2 AgNO3 → 2 Ag + 1 Ni(NO3)2

If you have 22.9 grams of Ni and 112 grams of AgNO3 which reactant is the limiting and
excess reactant? How many grams of nickel (II) nitrate are formed?

Limiting Reactant -

Excess Reactant -

Mass of Ni(NO3)2 -

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
