What is the influence of temperature on a chemical change?

Answers

Answer:

Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

The Answer Is A

Explanation:

A chemist is using 341 milliliters of a solution of acid and water. If 16.1% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answers

We need to assume that the acid in question is a liquid (not a solid or a gas),

and we need to assume that the 16.1% is specified as 16.1% (v/v) ,

where "v/v" means volume in volume,

meaning 16.2 milliliters of that acid are contained in 100 milliliters of the solution of acid and water.

With those assumptions, the ratio of acid volume to solution volume is

x/342 = 16.1/100 , where x= number of milliliters of acid in the 342

milliliters of solution.

x/342 = 16./100 ---> x=342x16.1/100 ---> x=55 (Rounded)
