Experiments have shown that the equilibrium constant Kp for the reaction NO(g) + NO2(g) ⇌ N2O3(g) is 0.03. A chamber with a cons

zepelin [54]

Answer:

The reaction will shift to the right

Explanation:

In the reaction:

NO(g) + NO₂(g) ⇌ N₂O₃(g)

Kp of reaction is:

$kP = \frac{P_{N_2O_3} }{P_{NO}P_{NO_{2}}}$ = 0.03

Where P represents the pressures in equilibrium

Replacing in the kP formula the initial pressures:

$\frac{50MPa}{200MPa*250MPa}$ = 0.001

As the Reaction quotient (Q) is less than kP, the reaction will shift to the right producing more N₂O₃ until Q = kP.

CAN SOMEONE HELP ME WITH THESE QUESTIONS I WILL GIVE ALL MY POINTS 5 STARS AND THANKS AND BRAINLY ALL I ASK IS WHENN YOU ANSWER

ira [324]

1. The bird has to adjust where it doves in for the fish because the light is refracted by the water, making it look like the fish is in a different position than it is.

2. The clock is reflected in the mirror, which sends each part of the image straight back.

4. Your first part is correct. The second part: The plant would look dark brown or black and red light. Red light has no green wavelengths to reflect, and the red light would be absorbed by the leaf, making it appear almost black.

LMK if you have questions.

Determine how many grams of silver would be produced, if 12.83 x 10^23 atoms of copper react with an excess of silver nitrate. G

likoan [24]

Answer: The amount of silver produced in the given reaction is 459.63 g.

Explanation:

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of atoms.

For the given chemical equation:

$Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$

By Stoichiometry of the reaction:

1 mole of copper produces 2 moles of silver.

This means that, $6.022\times 10^{23}$ number of atoms of copper produces $2\times 6.022\times 10^{23}$ number of atoms of silver.

So, $12.83\times 10^{23}$ number of atoms of copper will produce = $\frac{2\times 6.022\times 10^{23}}\times 12.83\times 10^{23}=25.66\times 10^{23}$ number of atoms of silver.

We know that:

Mass of 1 mole of silver = 107.87 g

Using mole concept:

If, $6.022\times 10^{23}$ number of atoms occupies 107.87 grams of silver atom.

So, $25.66\times 10^{23}$ number of atoms will occupy = $\frac{107.87g}{6.022\times 10^{23}}\times 25.66\times 10^{23}=459.63g$

Hence, the amount of silver produced in the given reaction is 459.63 g.

When aluminum, Al, metal is dipped in an aqueous solution of hydrochloric acid, HCl, hydrogen gas H_2 is produced with the forma

erica [24]

Answer:

2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g)

Explanation:

The reaction is a displacement reaction.

The reaction does not commence immediately because the Al(aluminum) has Al2O3 (Aluminum oxide) which protect it from reacting with water.

It takes some time for the HCl (hydrochloric acid) to eat the coating, then the reaction proceed vigorously to produce hydrogen gas bubbles. Generally metals that are above hydrogen in the electrochemical series tend to displace Hydrogen from Hydrochloric acid. The more negative the electrochemical volts the more the tendency to lose electron. Metal above hydrogen have negative evolts while those below have positive evolts
