Describe the function of sodium and potassium in the generation of an action potential.

Biology
1 answer:
larisa [96]3 years ago
3 0

Answer:

The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.

Describe how the colors you see would change if you were to dive from the surface to down deep in the ocean. What would things l
Luden [163]

Answer:

Answer is below.

Explanation:

First of all, it would be much darker the deeper you go. On the surface, the light from the sun touches the ocean, making the ocean look like a light blue. However, if you dive down even deeper, you will find a darker blue, and later nothing (the sun won't touch the deep parts of the ocean, so all you would see is darkness). The short answer to this is: It's lighter around the surface, and darker the deeper you dive down into the ocean.

55.7 moles of PCl5 will decompose to produce how many moles of PCl3 and Cl2 combined ?Enter your answer correct to 1 decimal pla
Novosadov [1.4K]

Answer:

55.7 moles of PCl₃ and 55.7 moles of Cl₂

Explanation:

The balanced chemical equation for the reaction in which phosphorus pentachloride (PCl₅) is decomposed in phosphorus trichloride gas (PCl₃) and chloride gas (Cl₂) is the following:

PCl₅(g) → PCl₃(g) + Cl₂(g)

According to the stoichiometric coefficients, 1 mol of PCl₅ produces 1 mol of PCl₃ and 1 mol of Cl₂. So, the stoichiometric ratios reactant/product are: 1 mol PCl₃/1 mol PCl₅ and 1 mol Cl₂/1 mol PCl₅. Thus, we multiply the stoichiometric ratios by the number of moles of reactant:

1 mol PCl₃/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol PCl₃

1 mol Cl₂/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol Cl₂

Therefore, 55.7 moles of PCl₃ and 55.7 moles of Cl₂ are obtained from the decomposition of 55.7 moles of PCl₅.
