Ammonia is produced by the following reaction. 3H2(g) + N2(g) ---> 2NH3(g) When 7.00 g of hydrogen react with 70.0 g of nitrogen, hydrogen is considered the limiting reactant because

Answers

Answer 1

Answer: To determine the limiting reactant, we first calculate the number of moles of the reactant.

7.00 g H2 ( 1 mol / 2.02 g ) = 3.47 mol H2
70.00 g N2 ( 1 mol / 28.02 g) = 2.50 mol N2

From the balanced reaction, we see that there is a 3 is to 1 ratio of the reactants. So, for every 3 moles of H2 we need 1 mole of N2. Given the amount of reactant, for 2.50 moles of N2 we need 7.5 moles of H2 which obviously we have a lesser amount. Hydrogen is the limiting reactant.

Answer 2

Answer: The correct answer is A

metallurgy
inductive reasoning

Answers

The study of metals and the process for refining and making things from them is called metallurgy.Metallurgy is said to be the scientific study both of the extraction and refining process of metals from their ores.This process includes steps such as grinding of the ore also called ore pulverization.Ore is crushed to increase its surface area for purpose of increasing the level of its reactivity.Sometimes, the ore is heated in the presence of oxygen to turn the ore into and oxide. This process is known as roasting.

the answer would be:

C. metallurgy

A serving of fish contains 50 g protein and 4 g of fat. If protein has a caloric value of 4 kcal/g and fat has 9 kcal/g, how many kcal are in the serving? Round off the energy value for each food group to the tens place.

Answers

Answer: 240

Explanation:

Final answer:

A serving of fish contains 236 kcal.

Explanation:

To find the number of kilocalories (kcal) in a serving of fish, we need to calculate the energy from protein and fat separately and then add them together. The energy from protein is calculated by multiplying the amount of protein by its caloric value of 4 kcal/g. So, 50 g of protein provides (50 g) x (4 kcal/g) = 200 kcal. The energy from fat is calculated in the same way, so 4 g of fat provides (4 g) x (9 kcal/g) = 36 kcal. Finally, we add the energy from protein and fat together, resulting in a total of 200 kcal + 36 kcal = 236 kcal in the serving of fish.

Which statement explains why a molecule of CH4 is nonpolar?(1) The bonds between the atoms in a CH4 molecule are polar.
(2) The bonds between the atoms in a CH4 molecule are ionic.
(3) The geometric shape of a CH4 molecule distributes the charges symmetrically.
(4) The geometric shape of a CH4 molecule distributes the charges asymmetrically.

Answers

The answer is the option (3) The geometric shape of a CH4 moleculedistributes the charges geometrically. the CH4 is a tetrahedral with theCarbon atom in the center and the four H atoms in the vertices of thetetrahedral. The C-H bond angles are all identical which makes themolecule perfectly symmetrical and so any dipolar moment will cancelmaking the molecule non polar.

The following statement explains why a molecule of $\text{CH}_4$ is nonpolar:

$\boxed{\left( 3 \right){\text{ The geometric shape of a C}}{{\text{H}}_4}{\text{ molecule distributes the charge symmetrically}}}$ .

Further explanation:

Covalent Bond

This type of bonding takes place when the bonded atoms mutually share electron pairs between them. It is also called the molecule bond. The chemical compounds formed as a result of this bond are called chemical compounds.

The polarity of any bond is primarily governed by two factors; electronegativity difference and symmetry. A bond is said to be polar if the bonded atoms have a considerable molecular bondelectronegativity difference between them. But if there is very small or no electronegativity difference between the bonded atoms, the resulting bond is nonpolar in nature.

Symmetry is another factor responsible for the polarity of the bond. The charge distribution is symmetrical in case symmetry is present in the molecule and as a result, the molecule is said to be nonpolar. But if there is asymmetry in the shape of the molecule, it will be polar in nature.

The electronegativity difference between carbon and hydrogen atoms in $\text{CH}_4$ molecule is very small or negligible so the bonds between the atoms in $\text{CH}_4$ are nonpolar in nature. But the hydrogen atoms are placed in symmetrical positions with respect to the central carbon atom, imparting symmetry to $\text{CH}_4$ molecule and therefore it is nonpolar (For structure, refer to the attached image).

What types of epithelial cells would you expect to find in an area of the body where diffusion of nutrients needs to occur?1) Cuboidal
2) Columnar
3) Squamous

Answers

The type of epithelial cells that would be found in an area of the body where diffusion of nutrients needs to occur is squamous.

Epithelial cells refer to the cells that are vital in the lining of the surface of the body. Epithelial cells can be found on the blood vessels, skin, and urinary tract.

It should be noted that epithelial cells are important as they act as a protective barrier and help in stopping viruses from getting inside the human body.

It should be noted that squamous can be found in an area of the body where diffusion of nutrients needs to occur. They're flat cells and they are usually thin and resembles the scale of fishes.

In conclusion, squamous can be found on the surface of the skin.
