Answer:
Vitamin C is water-soluble and not stored in your body
In contrast to fat-soluble vitamins, water-soluble vitamins do not get stored within the body. Instead, the vitamin C that you consume gets transported to your tissues via body fluids, and any extra gets excreted in urine ( 1 ).
Answer:
The reason vitamin C isn't stored well is because your body can't make it, and vitamin C is a water-soluble vitamin. This means it dissolves in water, and what your body doesn't use right away is excreted through urine. Thus, it is not stored in our body to a significant extent.

1. How many atoms are in 1.00 mole of H?
Answer:
6.022 × 1023
Explanation:
1 mole of H:
The definition of Avogadro's number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with an atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms. 1.45⋅6.02⋅1023≈8.73⋅1023 hydrogen atoms.
1 mole:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
in an H:
H: 2×2×4=16 atoms of hydrogen. C: It only appears once and without a subscript, so 1×4=4 . O : Like carbon, it's 1×4=4 .
1.00 mole:
One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

C. 4.14 teaspoons
D. 18 teaspoons
Answer:it's b hope that help
The molar mass of water is 18 g. Given that there are 0.23 teaspoon for every 1 g. Thus , for 18 g there would be 4.14 teaspoons.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called one mole of that substance. The mass of a compound or molecule containing these much atoms is called its molar mass.
Molar mass of water is 18 g. Thus, it means that one mole of water weighs 18 g. Given that for every 1 g of water there are 0.23 teaspoon. Thus, number of teaspoons for one mole or 18 g of water is:
number of teaspoons = 18 g × 0.23 /1 g
= 4.14 teaspoons.
Therefore, 4.14 teaspoons are required for one mole of water.

List these distance units in order from smallest to largest: nm,m,km,dm
Answer:
nm, dm, km, m
Explanation:
1 nanometer = 1e-12 (0.000000000001) kilometers
1 decimeter = 1e-4 (0.0001) kilometers
1 kilometer = 1 kilometer
Regardless of whether 'm' stands for mile or meter, it's still larger than all of these being approx. 1.61 and 1e-3 (0.001) kilometers respectively.

Gaseous methane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water. If 0.809g of carbon dioxide is produced from the reaction of 0.80g of methane and 2.1g of oxygen gas, calculate the percent yield of carbon dioxide.
Be sure your answer has the correct number of significant digits in it.
Answer:
About 58%.
Explanation:
We first need to write the balanced chemical equation:
[tex]\displaystyle \text{CH$_4$(g)} + 2\text{O$_2$(g)} \longrightarrow \text{CO$_2$(g)} + 2\text{H$_2$O(g)}[/tex]
We are given that 0.809 g of carbon dioxide was produced from the reaction of 0.80 g of methane and 2.1 g of oxygen gas. We want to calculate the percent yield of carbon dioxide.
First, determine the limiting reagent. We can convert each initial mass to the mass of carbon dioxide using stoichiometry. The molar mass of methane is 16.05 g/mol and the molar mass of carbon dioxie is 44.01 g/mol. From the equation, every one mole of carbon dioxide is produced from every one mole of methane and every two moles of oxygen gas.
0.80 g of methane will (theoretically) produce:
[tex]\displaystyle \begin{aligned} 0.80 \text{ g CH$_4$} &\cdot \frac{1 \text{ mol CH$_4$}}{16.05 \text{ g CH$_4$}} \cdot \frac{1 \text{ mol CO$_2$}}{1 \text{ mol CH$_4$}} \cdot \frac{44.01 \text{ g CO$_2$}}{1 \text{ mol CO$_2$}} \\ \\ & = 2.2 \text{ g CO$_2$}\end{aligned}[/tex]
2.1 g of oxygen gas will (theoretically) produce:
[tex]\displaystyle \begin{aligned} 2.1 \text{ g O$_2$} & \cdot \frac{ 1 \text{ mol O$_2$}}{32.00 \text{ g O$_2$}} \cdot \frac{1 \text{ mol CO$_2$}}{2 \text{ mol O$_2$}}\cdot \frac{44.01 \text{ g CO$_2$}}{1 \text{ mol CO$_2$}} \\ \\ & = 1.4 \text{ g CO$_2$} \end{aligned}[/tex]
Hence, oxygen gas is the limiting reagent. A maximum of 1.4 g of carbon dioxide can be produced.
To calculate the percent yield, we divide the actual yield by the theoretical yield. The actual yield was 0.809 g and the theoretical yield is 1.4 g. Hence:
[tex]\displaystyle \begin{aligned} \%\text{Yield} & = \frac{\text{Actual}}{\text{Theoretical}} \times 100\% \\ \\ & = \frac{(0.809\text{ g CO$_2$})}{(1.4\text{ g CO$_2$})} \times 100\% \\ \\ & = 58\%\end{aligned}[/tex]
In conclusion, the percent yield of carbon dioxide is about 58%.

Which charge does iron (Fe) have in iron sulfate (FeSO4)?
A) -1
B) +2
C) -2
D)+2
The charge on iron (Fe) in iron sulfate (FeSO₄) is equal to +2. Therefore, option (D) is correct.
What are the ionic charges?The ionic charge can be described as the oxidation number of the chemical species. The cation carries a positive ionic charge while Anion carries a negative ionic charge. The number of electrons gained or lost by an atom decides the charge carried by ions.
In the modern periodic table, the elements placed on the left side are electropositive and act as metals because they can donate one or more electrons. The elements placed on the right side are electronegative as they can accept one or more electrons and get a negative charge on their ions.
Considering that the charge on the iron is x, We know that charge on the sulfate ion is -2.
x - 2 = 0
x = +2
Therefore, the charge on iron (Fe) in iron sulfate (FeSO₄) is +2.
