Answer:

The total pressure is 0,804 atm

Explanation:

We use Dalton's law according to which the sum of the partial pressures is equal to the total pressure of a gas mixture. We convert the pressure in Pascals to atmosphere (it can also be done in reverse):

101300Pa ----1 atm

4500Pa----x= (4500Pa x 1atm)/101300Pa= 0,044 atm

P total= p1 + p2= 0,76 atm + 0,044 atm=0,804 atm

After passing through pyruvate dehydrogenase and the citric acid cycle, one mole of pyruvate will result in the formation of ___
mamaluj [8]

Answer:

The answer to be filled in the respective blanks in question is

3 and 1

Explanation:

So, we know that the formation of cabon-dioxide mole and that of Adenosin-Tri-Phosphate (ATP) moles will be in the ratio of 3:1 i.e., three carbon-di-oxide moles and 1 ATP mole.

Therefore, we can say that one pyruvate mole when passed through citric acid cycle and pyruvate dehydrogenase yields carbon-di-oxide and ATP moles in the ratio 3:1

Lake Minnetonka in Southern Minneosta is buffer solution

Explanation:

One can conclude from the observation that Lake Minnetonka is a buffer solution. A buffer solution is a special solution that resist changes in pH or pOH when a small amount of an acid or base is added.

  • Buffers are solutions in equilibrium with a fairly constant pH.
  • They are  aqueous solutions containing weak acids and their salts or weak bases and their salts.
  • Since the pH of water sample from Lake Minnetonka did not change, it is a buffer.

A company wants to start a nuclear power plant as a away to produce clean energy. They want to use the same reaction that's used
jok3333 [9.3K]

B.

The energy in nuclear fusion can't be generated in a controlled manner hence difficult to use in a nuclear power plant as a away to produce clean energy.

Explanation:

The reactions in thermonuclear bombs use very highly enriched radioactive elements that release a lot of energy at a go hence the enormous explosions they cause. A nuclear power plant would require this enormous energy to be released slowly  to generate electricity. It requires great technology to control the release of this nuclear energy because it requires the control of the rate of chain reactions occurring at a particular time.  If the chain reactions are too many at a time, the power plant could explode.

If 200 mL of water is evaporated from 400 mL of 0.5 M aqueous salt solution, what is the resulting concentration? 1. 2.5 × 10−1
ikadub [295]

Answer:

None of these

Explanation:

Using the dilution formula;

M1V1 = M2V2

where M1 is the initial concentration, V1 is the initial volume, M2 is the concentration attained while V2 is the new volume.

Therefore;

M2 = M1V1/V2

     = (400 mL × 0.5) / 200 mL

     = 1 M

Therefore, the resulting concentration is 1M

Thus, the correct answer is "none of these"
