The concentration of ca 2 in blood plasma in equivalent if its concentration is 0.0080.
Concentration means the amount of or parts in terms of the alternative components. For acid–base reactions, the equivalent weight of an acid or base is the mass which materials or reacts with one mole of hydrogen
In chemistry, equal weight (additionally known as gram equal is the mass of 1 equivalent, that is the mass of a given substance as a way to integrate with or displace a fixed amount of any other substance. The equivalent weight of an detail is the mass which combines with or displaces 1.008 gram of hydrogen or eight. Zero grams of oxygen or 35.five grams of chlorine. those values correspond to the atomic weight divided through the usual valence for oxygen as example that is sixteen.
Charge on one Ca 2+ ion = + 2 .
Concentration of calcium ion = 0.0040M
⇒ Concentration of Ca 2 + in blood plasma = 0.0040 × 2
= 0.0080 equivalent Ca 2 answer

Answer;
- A teacher takes the cap off a permanent marker. A few minutes later, students at the back of the classroom complain about the odor of the marker.
- A cooking school student burns a piece of toast. Soon, the entire kitchen smells like burnt toast.
- Toxic fumes produced by a chemical factory are detected in the air in a town several miles away.
<h3><u>Explanation;</u></h3>
- Diffusion is a type of passive transport that involves the movement of particles from a region of high concentration to a region of low concentration.
- <em><u>Diffusion takes place in liquids and gases, since their particles can move randomly from one region to another.</u></em>
- <em><u>Therefore, diffusion results from the random movement of particles in which the net movement is down the concentration gradient that is, from a region of high concentration to a region of low concentration.</u></em>
That way you have a back up plan. And your prepared
By looking closely into the given balanced chemical reaction, it can be deduced that the number of moles needed for every mole of FeO is only 2/3. Calculating for the number of moles of aluminum,
x = (13.2 moles FeO)(2 mols Al/3 moles FeO)
x = 8.8 moles Al
Answer: 8.8 moles Al
