Transport of Na+ from a place of low concentration to a place of higher concentration. <u>This is the right answer.</u>

<u />

The sodium-potassium pump is the most common and well-known example of active transport. At the cell membrane, the sodium-potassium pump moves 3 sodium ions out of the cell and two potassium ions into the cell per ATP. Examples of active transport include the uptake of glucose in the human intestine and the uptake of minerals and ions into the root hair cells of plants.

One of the greatest examples of active transport is the movement of calcium ions out of cardiomyocytes. Cells secrete proteins such as enzymes, antibodies, and various other peptide hormones. Amino acids are transported across the intestinal mucosa of the human intestine. The movement of ions or molecules across cell membranes to regions of a higher concentration is assisted by enzymes and requires energy.

Explain why a potassium atom would not bond with a calcium atom?

docker41 [41]

Answer:

Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.

g A piece of solid Zn metal is put into an aqueous solution of Cu(NO3)2. Write the net ionic equation for any single-replacement

Nimfa-mama [501]

Answer:

Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)

Explanation:

Let's consider the molecular single displacement equation between Zn and Cu(NO₃)₂

Zn(s) + Cu(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Cu(s)

The complete ionic equation includes all the ions and insoluble species.

Zn(s) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ Zn²⁺(aq) + 2 NO₃⁻(aq) + Cu(s)

The net ionic equation includes only the ions that participate in the reaction and insoluble species.

Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)

The energy produced by the snack in an experiment is calculated to be 41,800 J/g. What is the energy of the snack in Calories/

Goryan [66]

The energy of the snack in calories per gram is 9983.3 Calories/gram.

<h3>What is the energy of a snack?</h3>

The energy that is contained in a snack is obtained from a calorimeter when the snack is burnt in a calorimeter. The mass of the snack that is burnt is measured in terms of energy output of the calorimeter.

If 1 calorie = 4.18J

x calorie = 41,800 J

x = 41,800 J * 1 calorie/4.18J

x = 9983.3 Calories/gram

How do you know if a new substance is formed in a chemical equation

S_A_V [24]

<u>Answer:</u> The indicators written will identify a new substance is formed in a chemical equation.

<u>Explanation:</u>

A chemical equation is defined as the equation in which reactants and products are present and are separated by a right arrow.

$\text{Reactants}\rightarrow \text{Products}$

Indicators of a chemical reaction are:

Formation of a precipitate
Evolution of gas
Formation of bubbles
Color change
Specific odor
Change in temperature

Hence, the indicators written will identify a new substance is formed in a chemical equation.
