Answer:

Explanation:

a) For diatomic gas: Translational motion = 3 and rotational motion = 2

∴ Total (internal energy) = 3 + 2 = 5

b) Translational + Rotational + Vibrational = 3 + 2 + 1 = 6

Vegetarian diets can provide high levels of antioxidants and a lipid profile that can help prevent coronary disease. However, th
Arada [10]

Answer:

The correct option is: "Vitamin B12 (cobalamin) is not found in the vegan diet and is very low in the lacto-vegetarian diet"

Explanation:

Homocysteine is a VERY IMPORTANT type of amino acid, a chemical that the body uses to make proteins. Normally, vitamin B12, vitamin B6, and folic acid break down homocysteine and transform it into other substances that the body needs. There should be very little homocysteine left in the bloodstream. If you have high homocysteine levels in your blood, that could be a sign of a vitamin deficiency of the vitamins listed above, a heart condition, or a rare inherited disorder.

How many atoms of iodine are in 12.75g of CaI2? Hint. How many Iodines are there in one CaI2 particle?
xenn [34]

Answer:

5.225x10^{22}atoms\ I

Explanation:

Hello!

In this case, since 12.75 g of calcium iodide has the following number of moles (molar mass = 293.89 g/mol):

n_{CaI_2}=12.75gCaI_2*\frac{1molCaI_2}{293.89gCaI_2}=0.0434molCaI_2

In such a way, since 1 mole of calcium iodide contains 2 moles of atoms of iodine, and one mole of atoms of iodine contains 6.022x10²³ atoms (Avogadro's number), we compute the resulting atoms as shown below:

atoms\ I=0.0434molCaI_2*\frac{2molI}{1molCaI_2} *\frac{6.022x10^{23}atoms\ I}{1molI} \\\\atoms\ I = 5.225x10^{22}atoms\ I

Best regards!
