Answer:
The partial pressure of oxygen in the mixture is 296 mmHg.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone.
This relationship is due to the assumption that there are no attractive forces between the gases.
So, in this case, the total pressure is:
PT=Phelium + Pnitrogen + Poxygen
You know:
- PT= 756 mmHg
- Phelium= 122 mmHg
- Pnitrogen= 338 mmHg
- Poxygen= ?
Replacing:
756 mmHg= 122 mmHg + 338 mmHg + Poxygen
Solving:
756 mmHg - 122 mmHg - 338 mmHg = Poxygen
Poxygen= 296 mmHg
<u><em>The partial pressure of oxygen in the mixture is 296 mmHg.</em></u>
Answer:
solar thermal energy can be even used to produce air conditioning I'm not understanding your question due to the fact that solar thermal energy produces hot water provides heat for houses and warms buildings great for space heating and can provide electricity
The Options are as follow,
<span>a.
it has 13 protons c. it has 13 neutrons </span>
<span>b.
it has 13 electrons d. it
has 7 neutrons</span>
Answer:
Option-d is the correct answer.
Explanation:
As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,
<span> Atomic Mass = # of Protons + # of Neutrons --- (1)</span>
Since;
Atomic Mass = 13
And,
# of protons = 6 (as number of protons = atomic number)
Putting values in equation 1,
13 = 6 - # of Neutrons
Solving for Number of Neutrons,
# of Neutrons = 13 - 6
# of Neutrons = 7
Anabolism is characterized as the assembly of large molecules from small molecules.
Anabolism is the set of chemical reactions of molecular synthesis of the organism considered. It is the opposite of catabolism, set of degradation reactions.
The reactions of the anabolism are reductions and are not spontaneous, they are endergonic reactions that is to say that they require a contribution in energy to take place. We can also talk about biosynthesis.
These reactions allow living organisms to synthesize essential metabolites from the basics provided by the diet and result in the building or renewal of tissues.
Examples: photosynthesis, protein biosynthesis.
