Answer:

Volumen C6H8O6(sln) = 2.569 L ≅ 2.6 L

Explanation:

vitamin C ≡ ascorbic acid (C6H8O6)

∴ vitamin C/daily = 75.0 mg/d

∴ molar mass C6H8O6 = 176.12 g/mol

solution:

∴ <em>C</em> C6H8O6 = 0.002486 mol/L

⇒ ppm C6H8O6 = (0.002486 mol/L)*(176.12 g/mol)*(1000 mg/g)

⇒ ppm C6H8O6 = 437.834 mg/L

for a 15.0 day:

⇒ Volume C6H8O6(sln) = (75.0 mg/d)*(L/437.834 mg)*(15.0 d)

⇒ Volume C6H8O6(sln) = 2.569 L

What does buffer do?? (Chemistry)​
pogonyaev
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.

How reactive is an atom of Sodium(Na) and why?
s344n2d4d5 [400]
3rd one:
it is very reactive because it does not have a full Valence shell.

this is because it's in group 1 so it has one electron in its outer shell, and it wants to have a full outer shell ( which it can gain by losing the electron in a reaction).

Hope this helps :)

Answer:

C

Explanation:

the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.
