Consider the following chemical equilibrium:

N2(g) + 3H2(g) ⇌ 2NH3(g)

Now write an equation below that shows how to calculate Kc from Kp for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator.

Expert Answer

Step 1

A reversible chemical reaction can move in either forward or backward direction. The stage of a reversible reaction at which the rate of forward and backward reaction become equal to each other is called an equilibrium stage.

Step 2

The equilibrium constant for a reaction is the ratio of equilibrium concentration of product and reactant. If the reaction is given in gaseous state, then the equilibrium pressure must be considered.

Step 3

For a specific enzyme/substrate system, which condition will always result in an increase in Vo (assuming nothing else changes)?

inessss [21]

<span>a decrease in Km and an increase in Vmax
km is the constant that relates how thick the volume of the substrate in terms of concentration when the speed is a large portion of the most extreme. They increment Km by meddling with the joining process that makes them stick together wit the substrate, however they have any effect with regards to Vmax since since the sticking process to ES did not occur</span>

Aluminum costs about 85 cents per pound (453.592 g). How much is one atom of aluminum?

kakasveta [241]

One aluminum atom will cost 0.84 × 10⁻²³ cents.

Explanation:

Aluminium costs 85 cents per 453.592 grams.

number of moles = mass / atomic weight

number of moles of aluminium = 453.592 / 27 = 16.8 moles

To calculate the number of aluminum atoms we use the Avogadro's number:

if 1 mole of aluminum contains 6.022 × 10²³ aluminum atoms

then 16.8 moles of aluminum contains X aluminum atoms

X = (16.8 × 6.022 × 10²³) / 1 = 101.17 × 10²³ aluminum atoms

Now, taking in account the aluminium price, we devise the following reasoning:

if 101.17 × 10²³ aluminum atoms costs 85 cents

then 1 aluminum atom costs Y cents

Y = (1 × 85) / (101.17 × 10²³) = 0.84 × 10⁻²³ cents

|||Good points and Brainliest||| Explain the biological pump <br> (have at least 3 sentences pls)

Ber [7]

Answer:

The biological pump or the marine carbon pump is the title for multiple processes leading to separation of carbon from multiple sources of water. Biological pumping is partially responsible for the cycling of organic matter. This process can lead to loss of contact between carbon and the atmosphere for thousands of years.
