What is the influence of temperature on a chemical change?
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.

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.
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)

How is science based on observation used as evidence? How can evidence be used?
Answer:
Explanation:
Researchers gather empirical evidence through experimentation or observation. Empirical evidence is information acquired by observation or experimentation. Scientists record and analyze this data. The process is a central part of the scientific method.
Answer:
Science Produces Explanations That Can Be Tested Using Empirical Evidence. Science requires that scientific explanations of phenomena be based on events or mechanisms that can be observed in the natural world. This is how science builds a base of shared observations and ideas to which new knowledge can be added.

What kinds of changes happen to water as it goes through the water cycle? Are they physical or chemical?
Answer:
When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy.
Explanation:
and its physical
Answer:
The answer is Physical
Explanation:
The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy. They are all the same but no matter what state it's in it's still water so it's physical.
