The human body can get energy by metabolizing proteins, carbohydrates or fatty acids, depending on the circumstances. Roughly sp

Answer:

Explanation:

The oxidation state corresponds to the charge of each atomic ion. An increase indicates oxidation of the element while a decrease reflects reduction of the element.

2AgCl+Zn⟶2Ag+ZnCl2

Zinc undergoes oxidation, while Ag experiences reduction.

Ag⁺ changes to Ag (oxidation state decreases), thus Ag is reduced.

Zn alters to Zn⁺² (oxidation state increases), hence Zn is oxidized.

4NH₃+3O₂⟶2N₂+6H₂O

The oxidation state of nitrogen in ammonia is -3

whereas it is zero in elemental nitrogen.

An increase in the oxidation state indicates nitrogen is oxidized.

The oxidation state of oxygen is zero when in molecular oxygen and -2 when in water. Therefore, the oxidation state decreases, indicating oxidation is reduced.

Fe₂O₃+2Al⟶Al₂O₃+2Fe

The oxidation state of Fe in Fe₂O₃ is +3, switching to zero in Fe, so iron is reduced.

Aluminum's oxidation state is zero in Al, rising to +3 in Al₂O₃, indicating it is oxidized.

Answer:

The reaction will proceed in the forward direction, resulting in the reduction of NiO to Ni

Explanation:

Step 1: Provided data

Kp = 6.0 * 10²

Pressure of CO = 150 torr

Total pressure remains under 760 torr

Step 2: The balanced reaction equation:

NiO(s) + CO(g) ⇆ Ni(s) + CO2(g)

Step 3: Determine P(CO) and P(CO2)

For this equilibrium, the Kp expression is:

Kp = P(CO2)/P(CO) = 6.0*10^2

Given that NiO and Ni are solids, they do not affect the Kp

⇒ with P(CO) = 150 torr

⇒ P(CO) = 760 - 150 = 610 torr

Step 4: Calculate the reaction quotient

Q = 610/150 = 4.1

Since Q is significantly less than Kp, there are more reactants than products. Some reactants will convert into products, driving the reaction rightward.

Thus, the reaction will proceed forward, leading to the reduction of NiO to Ni.

Result:

I believe it’s called Trinitrogen Pentaseleniumide

Explanation:

Tri means three

Penta means five

The second element concludes with -ide

The correct answer is Option A. The calculation goes as follows: Number of millimoles of Na3PO4 = 1 × 100 = 100 Number of millimoles of AgNO3 = 1 × 100 = 100 Dissociating 1 mole of Na3PO4 yields 3 moles of sodium ions and 1 mole of phosphate ions, whereas 1 mole of AgNO3 releases 1 mole of Ag+ and 1 mole of NO3-. The Ag+ ion concentration becomes negligible since it forms a precipitate with the phosphate ion, indicating that the concentration of phosphate ions is also low. With 100 millimoles of Na3PO4, we get 300 millimoles of Na+ and 100 millimoles of PO43-, and with 100 millimoles of AgNO3 we have 100 millimoles of Ag+ and 100 millimoles of NO3-. Thus, the order of increasing concentration is: PO43- < NO3- < Na+.
