Answer:
When the temperature of an object increase, the object's particle move faster.
Explanation:
Energy in form of the heat can be absorbed by the object, energy is translated to object's particles. In that moment, energy is transformed in another form - kinetic energy. Kinetic energy manifest as a faster particle movement ( or vibration ).
We first calculate the number of moles of K2CrO4 by multiplying the volume with the molarity.
n = (25/1000) x (3 M) = 0.075 mol K2CrO4
Then, from the balanced chemical equation, each mole of K2CrO4 will produce 1 mole PbCrO4 with molar mass of 323.2 g/mol.
(0.075 mol K2CrO4)(1 mol PbCrO4/1 mol K2CrO4) x (323.2 g/mol)
= 24.24 grams PbCrO4
