Cellular respiration is the process of taking in glucose (sugar) and converting it into usable energy (ATP) so therefore the first stage would be taking the glucose into your bloodstream.
An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.
<span>4 amu / (1/1836 amu) = 7344 </span>
<span>Therefore, an alpha particle is 7344 times heavier than an electron.
Hope this answers the question. Have a nice day.</span>
Answer:
a strong electrolyte
Explanation:
Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.
- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)
- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are “strong” because their ionization state is independent of pH.
Strong Electrolye fits the condition and hence is the correct option.
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>
