While getting ready to conduct an experiment, a student prepares 150 mL of 42.2% potassium chromate by mass solution. If the density of the solution is measured to be 1.40 g/mL, how many grams of potassium chromate were used to make the solution?

Give your answer with two decimal places.

c is the answer because when something is left after something evaporates that shows the chemical change.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
