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

Milk is a liquid, carbon dioxide is a gas and rock is a solid.

The increase in energy will cause the reactants particles to move faster, which will increase their temperature and lead to a faster reaction rate.

The reaction rate is the speed at which reactants are converted into products.

The collision theory states that a certain fraction of the collisions (successful collisions) cause significant chemical change.  

The successful collisions must have enough energy (activation energy).  

If the surface area and temperature are increased, speed of reaction also increased.

Particles are in constant, random motion and possess kinetic energy, molecules faster and have more collisions.  

answer; natural resources;

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
