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.

Draw the structure for cis-2,3-dibromo-2-hexene.

padilas [110]

First, draw the 2-hexene. Th is is a molecule of six carbons with a double bond in the second carbon:

      CH3 - CH = CH2 - CH2 - CH2 - CH3

Secong, put one Br on the second carbon and one Br on the third carbon:

    CH3 - CBr = CBr - CH2 - CH2 - CH3

Third, cis means that the two Br are placed in opposed positions, this is drawn with one Br up and the other down. So, you need to represent the position of the Br in the space:

      H   Br        H    H      H
       |    |           |       |    |
H - C - C = C - C - C - C - H
       |           |    |       |    |
      H          Br H     H      H

The important fact to realize is that the two Br are in opposed sides of the molecule.

Hydrogen iodide decomposes slowly to H2 and I2 at 600 K. The reaction is second order in HI, and the rate constant is 9.7×10−6M−

Lady bird [3.3K]

Answer : The molarity after a reaction time of 5.00 days is, 0.109 M

Explanation :

The integrated rate law equation for second order reaction follows:

$k=\frac{1}{t}\left (\frac{1}{[A]}-\frac{1}{[A]_o}\right)$

where,

k = rate constant = $9.7\times 10^{-6}M^{-1}s^{-1}$

t = time taken = 5.00 days

[A] = concentration of substance after time 't' = ?

$[A]_o$ = Initial concentration = 0.110 M

Now put all the given values in above equation, we get:

$9.7\times 10^{-6}=\frac{1}{5.00}\left (\frac{1}{[A]}-\frac{1}{(0.110)}\right)$

$[A]=0.109M$

Hence, the molarity after a reaction time of 5.00 days is, 0.109 M

What happens to the population growth in a logistic growth pattern as it approaches carrying capacity?

AveGali [126]

B. slows down is your answer, obviously as it approaches carrying capacity, there would be less available space to find in the place of inhabitance, so less and less population units would be able to find the place of inhabitance suitable for living, or can't find enough space to live in.

When the equation N=O/P is solved for P correctly, the equation should read:

zheka24 [161]

Given the equation N=O/P, solve for P by multiplying the left and right by P/N:

N * P/N = O/P * P/N

P = O/N
