Mass will increase drastically the GPE since mass since mass is a variable in the formula GPE= mgh. 2.
The correct option is D.
An endothermic reaction is a type of reaction that absorb energy from the environment, thus, the energy level of the product is always higher than that of the reactants. During endothermic phase change, the potential energy of the system always increases while the kinetic energy of the system remains constant. The potential energy of the reaction increases because energy is been added to the system from the external environment.
Answer:
A). Trial 1, because the average rate of the reaction is lower.
Explanation:
The first sentence elaborates that 'trial 1 had a lower level of concentration of the reactant that eventually led the reaction's average rate to fall.'
A trial having a higher level of concentration of a specific reactant will cause the concentration's average rate to rise. As per the graph provided, trial 2's average reaction rate is higher which shows that its concentration is greater and more reactive. However, the opposite happens in trial 1 where the amount of reactant is lesser in the concentration that leads the concentration to possess a lower rate of reaction. Thus, <u>option A</u> is the correct answer.

The moment the question mention Diamond, suspect Carbon as the answer. (1) element: C, carbon. Atomic number: 12 (double check on periodic table). (2) Not sure what does the question means, but I guess in the first shell, there will be 2 electrons and the 2nd shell will have 8 electrons (may need to explain it based on electron configuration involving s,p,d and f orbitals). (3) MOST undergoes sharing of electron so they form covalent bond with non metals.
