Question:

Three students are working with different substances to measure the chemical changes that occur. Chao is working with milk, Mia is working with carbon dioxide gas, and Ezra is working with rock. Which would best describe the way to treat each substance to get a faster reaction?

Chao should change the temperature, Mia should adjust the pressure, and Ezra should increase the surface area.

Chao should change the concentration, Mia should adjust the temperature, and Ezra should increase the surface area.

Chao should change the temperature, Mia should adjust the concentration, and Ezra should decrease the surface area.

Chao should change the concentration, Mia should adjust the pressure, and Ezra should decrease the surface area.

The correct option is;

Chao should change the temperature, Mia should adjust the pressure, and Ezra should increase the surface area.

Explanation:

From the question, it is observed that the required information is with regards to the factors influencing the chemical reaction of substances in different physical states.

Therefore, to increase the rate of reaction of a liquid, the number of kinetic energy of the particles is increased by raising the amount of reactants with energy for reaction in the liquid therefore, Chao should raise the temperature of the milk

Similarly, as the pressure of the carbon dioxide gas worked on by Mia is raised, the molecules of the carbon dioxide are brought closer together to react. Therefore Mia should adjust the pressure

To increase the amount of rock material taking part in a reaction, Ezra increases the contact area of the rock particles by increasing the surface area of the rock

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
