Chemistry
1 answer:
scZoUnD [109]3 years ago
4 0

Answer:

A balanced chemical equation explicitly provides you with the

a. conditions under which the reaction occurs.

b. molar masses of the reactants and products.

c. conversion factors needed to solve a stoichiometry problem.

d. mole ratios needed to solve a stoichiometry problem.

The correct answer to the question is

d. mole ratios needed to solve a stoichiometry problem.

Explanation:

A chemical reaction is sad to be balanced if it contains the complete list of reactants and products present in their relative proportions. The amounts of reactants and products can be calculated from a balanced chemical reaction equation by applying a process known as stoichiometry

An example of stoichiometry is the formation of two moles of water from one mole of oxygen and two moles of hydrogen

What’s the IUPAC name
hichkok12 [17]

Answer:

Methyl pentanoate.

Explanation:

Hello there!

In this case, according to the given information, we can see the correct structure will be:

                             O

                              ||

CH3CH2CH2CH2COCH3

Which matches with the structure of an ester due to the -COO- functional group. In such a case, the first part of the name is in function of the right side of the ester, in this case, methyl, followed by the left side, pentanoate, as it has five carbon atoms and is an ester (similar to an inorganic salt, but organic) and therefore, the name will be methyl pentanoate.

Regards!

Given the heat change per mole for the combustion of methanol (-726 kJ/mol), predict the heat change that would occur if 0.200 m
DochEvi [55]

Answer:

-145.2kJ

Explanation:

Enthalpy is an extensive property as its value depends on the amount of substance present in the system.

If the enthalpy for one mole of methanol = -726 kJ/mol;

The Enthalpy for 0.2 mol is given as;

Enthalpy = 0.200 * 726

Enthalpy = -145.2kJ

It would take -145.2kJ for 0.200 mol of methanol to undego the combustion reaction.

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.
