A radiator contains 10 quarts of fluid, 30% of which is antifreeze. how much fluid should be drained and replaced with pure anti
amm1812
Let x be the volume of fluid removed and the volume of pure antifreeze that is added. The concentration of antifreeze in the fluid is 0.3, the concentration in pure antifreeze is 1 and that in the final solution is 0.4 The volume of the final solution is 10.
(10 - x)(0.3) + x = 10(0.4)
0.3 + 0.7x = 0.4
x = 1/7 quarts

The volume that should be drained is 1/7 quarts

The students in Mrs. Smith's class used pH paper to measure the acidity levels between different samples of breakfast drinks. Th
masya89 [10]

Answer:

The most acidic solution had a pH of 3.27.

Explanation:

In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.

If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.

Conversely, the least acidic one had a pH of 3.88.

Ammonia is an important ingredient in many fertilizers. The main process by which ammonia is made is the Haber process. In this
creativ13 [48]
The best answer is "<span>High temperatures increase the activation energy of the reaction."

The Haber process is an exothermic reaction at room temperature. This means that the reaction actually favors the reverse reaction, especially when the temperature is increased. So why increase the reaction temperature?

The reason for this is that nitrogen is a very stable element. Therefore, more energy is needed to overcome the slow rate of reaction. So the reaction temperature must be low enough to favor a forward reaction, but high enough to speed up the reaction.</span>

1. Balanced Equation of the Reaction is as follow,

                                       2 HgO  --------->  2 Hg  +  O₂

2. The arrow labelled as a indicate ACTIVATION ENERGY. It is the minimum amount of energy required by the reactants to convert into products. This energy is obtained by providing heat to the system.

3. Transition State or Activated Complex:
I am trying to draw possible transition state. It could be the correct one and can be confirmed by theoretical computational study.

                                    Hg------O------O------Hg

Here the dashed lines mean that the bond between Hg and O are breaking and their length is increasing and the dashed line between oxygen atoms depict that the bond length is decreasing and bond formation is taking place.

4. This reaction is Endothermic because the energy of reactants is smaller than the energy of products. So, the difference in energies is obtained by providing heat to the system.

Note: I have answered these questions with respect to following energy profile.
