C. Outward pressure caused by heat
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:
2.355atm
Explanation:
To get the pressure of helium, we need to get the mole fraction of helium.
The total mole fraction for any mixture of gases equals 1. Hence to get the mole fraction of the helium, we simply subtract the addition of the mole fractions of neon and argon from 1.
This means - 1 - 0.47 - 0.23 = 0.3
Now, to get the pressure of the helium gas, we simply multiply the total pressure by 0.3. This is 0.3 * 7.85 = 2.355 atm
Answer:
A covalent bond is formed by an equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair. The covalent bonds are also termed molecular bonds.
