Nitrogen monoxide and hydrogen react to form nitrogen and water, like this: 2NO+2 H2(g)-N29)+2H2O(9) Write the pressure equilibr
lara31 [8.8K]

Answer:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp

Explanation:

The reaction is:

2NO + 2H₂ → N₂ + 2H₂O

The expression for Kp (pressure equilibrium constant) would be:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²

There is another expression for Kp, where you work with Kc (equilibrium constant)

Kp = Kc (R.T)^Δn

where R is the Ideal Gases constant

T° is absolute temperature

Δn = moles of gases formed - moles of gases, I had initially

How much stock solution is needed to make 250 mL of a 6.0 M solution. The stock solution has a molarity of 18 M.
Anuta_ua [19.1K]

Answer:

83 mL

Explanation:

Use the dilution equation M1V1 = M2V2

M1 = 18 M

V1 = ?

M2 = 6.0 M

M2 = 250 mL

Solve for V1 --> V1 = M2V2/M1

V1 = (6.0 M)(250 mL) / (18 M) = 83 mL

Explain what golden poison frogs, kokoe poison frogs, and black-legged poison frogs have in common
telo118 [61]
The family of poison dart frogs (Dendrobatidae) boasts over 245 species, displaying an astonishing array of colors and potency. The brilliant colors and patterns range from strawberry red, canary yellow, and sunny orange to metallic green and black with yellow polka-dots. When eaten, some merely taste bitter or irritate the predator’s mouth with burning or numbness; a few, however, are truly deadly, even to humans. the Golden poison frog is <span>the deadliest animal on land(poison wise) but the Black-legged poison frog is right up there next to it. both can easily kill a human. Though no deaths have been confirmed, the Kokoe poison frog can theoretically also kill a human, it is just as toxic as the black-legged poison frog. so what do they all have in common? they can all kill humans

i hope this helps, please give me brainliest </span>

While Cameron is intensely working out, his muscles begin to get sore and start to burn. What type of cellular
max2010maxim [7]

Answer:

1) Anaerobic respiration

2) Lactic acid

3) Stop the work out

Explanation:

1) Anaerobic respiration

Muscular anaerobic respiration to produce energy during exercises or workout, takes place when the level of oxygen available for the amount of energy being generated is not sufficient, and the balance generated energy is produced along with lactic acid by anaerobic respiration

2) Lactic acid

The produced lactic acid from the anaerobic respiration at the muscle sites results in a burning sensation being felt during strenuous muscular activity in the presence of low oxygen supply

3) Stop the work out

In order to stop the burning, the muscular activity is to be stopped, to allow the resumption of the aerobic process of energy production, and to allow the produced lactic acid to be cleared
