The number of ferrous ions present in jar are 3.1x 10^21.

<h3>Steps</h3>

Since we have 737 g, 5,896 servings are generated.

If one serving contains 49 mg of iron, then one can contains 49*5,896 mg of iron.

In other words, if made in a cast-iron pot, one jar of tomato sauce has 288,9 mg of iron.

The number of ferrous ions present in jar are 3.1x 10^21.

<h3>What exactly does nutritional biochemistry mean?</h3>

Nutritional biochemistry is the study of nutrition as a science that deals with physiology, medicine, microbiology, pharmacology, chemistry, and biology and uses these sciences for the investigation of health, diet, and nutrition as well as the research of disease and the administration of medications.

<h3>What does nutritional biochemistry teach you?</h3>

This covers a fundamental knowledge of molecular genetics, biostatistics, epidemiology, and metabolism. Learn the laboratory skills necessary for current biochemical and molecular investigations into diet and its impact on health and illness.

How many moles of oxygen gas (O2) are required to completely react with 10 moles of hydrogen gas (H2)?

Brums [2.3K]

Answer:

5 moles of oxygen are required.

Explanation:

Given data:

Moles of O₂ required = ?

Moles of H₂ present = 10 mol

Solution:

Chemical equation:

O₂ + 2H₂ → 2H₂O

Now we will compare the moles of oxygen and hydrogen.

H₂ : O₂

2 : 1

10 : 1/2×10 = 5 mol

5 moles of oxygen are required.

The reaction of 5.40 g of carbon with excess O2 yields 13.6 g of CO2. What is the percent yield of this reaction?

vazorg [7]

C + O2= CO2
$n = \frac{m}{mw}$
$n = \frac{5.4}{12} \\ n = 0.45 \: mol \: of \: carbon$
$n = \frac{13.6}{12 + 16 \times 2} \\ n = \frac{13.6}{44} \\ n = 0.31 \: mol \: of \: carbon \: dioxide$
CO2 is limit
5.4-3.72= 1.68 g of C is excess
5.4 g = 100%
3.72 g = x
x=68.9 %

Juli2301 [7.4K]

Answer:

PBr3 - Molecule , Polar

N2H2 - Molecule , (Polar in E- form and Non- polar in Z form)

C2H2 - Molecule , Non- Polar

N2 - Molecule , Polar

NCl3 - Molecule , Polar

SiF4 - Molecule , Non- Polar

NH3 - Molecule , Polar

F - Not- Molecule (atom)

H2 - Molecule and Non- Polar

Explanation:

Molecule : these are group of two or more atoms joined by strong force of attraction.

H2 is non- polar because it is homoatomic molecule.(made up of same element)

N2 is non- polar because it is homoatomic molecule.
