C. Decreasing the temperature

D. Raising the pressure​

<h3>Further explanation</h3>

Given

Reaction

2SO₂+O₂⇔2SO₃+energy

Required

Changes to  the formation of products

Solution

The formation of SO₃ is an exothermic reaction (releases heat)

If the system temperature is raised, then the equilibrium reaction will reduce the temperature by shifting the reaction in the direction that requires heat (endotherms). Conversely, if the temperature is lowered, then the equilibrium shifts to a reaction that releases heat (exothermic)  

While on the change in pressure, then the addition of pressure, the reaction will shift towards a smaller reaction coefficient  

in the above reaction: the number of coefficients on the left is 3 (2 + 1) while the right is 2

As the temperature decreases, the equilibrium will shift towards the exothermic reaction, so the reaction shifts to the right towards SO₃( products-favored)

And increasing the pressure, then the reaction shifts to the right SO₃( products-favored)⇒the number of coefficients is greater

How many moles of silver oxide (l) are needed to produce 4 moles of silver?
ozzi

The number of moles of silver oxide (I) needed to produce 4 moles of silver is 2 moles

<h3>Stoichiometry </h3>

From the question, we are to determine the number of moles of silver oxide (I) needed to produce 4 moles of silver

First, we will write the balaced chemical equation for the decomposition of silver oxide (I)

2Ag₂O(s) → 4Ag(s) + O₂(g)

This means, 2 moles of silver oxide (I) [Ag₂O] decomposes to give 4 moles of <u>silver </u>and 1 mole of oxygen gas.

From the <em>balanced chemical equation</em>, it is easy to deduce the number of moles of silver oxide (I) that would give 4 moles of silver.

Hence, the number of moles of silver oxide (I) needed to produce 4 moles of silver is 2 moles

What is the molarity of a solution with a volume of 974 mL containing 17 g of CuSO4
liberstina [14]

Answer : The correct option is, (A) 0.109 M CuSO_4

Solution : Given,

Mass of CuSO_4 = 17 g

volume of solution = 974 ml

Molar mass of CuSO_4 = 159.609 g/mole

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

Molarity=\frac{w\times 1000}{M\times V_s}

where,

w = mass of CuSO_4 (solute)

M = molar mass of CuSO_4

V_s = volume of solution in liter

Now put all the given values in the above formula, we get the molarity of solution.

Molarity=\frac{(17g)\times 1000}{(159.609g/mole)\times (974ml)}=0.109mole/L=0.109M

Therefore, the molarity of the solution is, 0.109 M

a bright violet line occurs at 435.8 nm in the emission spectrum of mercury vapor. What amount of energy, in joules, must be rel
Readme [11.4K]
<h3>Answer:</h3>

4.56 × 10^-19 Joules

<h3>Explanation:</h3>

We are given;

  • Wavelength of the wave as 435.8 nm

We are required to calculate the amount of energy released by an electron.

  • We know that the speed of the wave, c is 2.998 × 10^8 m/s
  • But, c = f × λ , where f is the frequency and λ is the wavelength
  • Energy of a wave is given by the formula;

E = hf , where h is the plank's constant, 6.626 × 10^-34 J-s

But, f = c/λ

Therefore;

f = (2.998 × 10^8 m/s) ÷ (4.358 × 10^-7 m)

  = 6.879 × 10^14 Hz

Thus;

Energy = 6.626 × 10^-34 J-s ×6.879 × 10^14 Hz

            = 4.558 × 10^-19 Joules

            =  4.56 × 10^-19 Joules

Therefore, the energy that must be released by the electron is 4.56 × 10^-19 Joules
