Nutritional biochemists have known for decades that acidic foods cooked in cast-iron cookware can supply significant amounts of

podryga [215]

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.

What<br>was the initial volume of the hydrogen in cm3?

svetlana [45]

Answer:

255.51cm3

Explanation:

Data obtained from the question include:

V1 (initial volume) =?

T1 (initial temperature) = 50°C = 50 + 273 = 323K

T2 (final temperature) = - 5°C = - 5 + 237 = 268K

V2 (final volume) = 212cm3

Using the Charles' law equation V1/T1 = V2/T2, the initial volume of the gas can be obtained as follow:

V1/T1 = V2/T2

V1/323 = 212/268

Cross multiply to express in linear form

V1 x 268 = 323 x 212

Divide both side by 268

V1 = (323 x 212)/268

V1 = 255.51cm3

Therefore, the initial volume of the gas is 255.51cm3

How much heat in kj is released by burning 9.5 grams of methane?

tatyana61 [14]

Methane is the compound CH4, and burning it uses the reaction:

CH4 + O2 -> CO2 + H2O, which is rather exothermic. To find the heat released by burning a certain amount of the substance, you should look at the bond enthalpy of each compound, and then compare the values before and after the reaction. In methane, there are 4 C-H bonds, which have bond energy of 416 kj/mol, resulting in a total bond energy of 1664 kj/mol. O2 is 494 kj/mol. Therefore we have a total of 2080 kj/mol on the left side. On the right side we have CO2, which has 2 C=O bonds, each at 799 kj/mol each, resulting in 1598 kj/mol, and H2O has 2 O-H bonds, at 459kj/mol each, resulting in a total of 2516 kj/mol on the right hand side. Now, this may be confusing because the left hand side seems to have less heat than the right, but you just need to remember: making minus breaking, which results in a total change of 436kj/mol heat evolved.

Now it is a simple matter of find the mols of CH4 reacted, using n=m/mr.

n = 9.5/16.042 = 0.592195 mol

Therefore, if we reacted 0.592195 mol, and we produced 436 kj for one mol, the total amount of energy evolved was 436*<span>0.592195 kj, or 258.197 kj.</span>
