The correct answer is option B. It equals the rate of formation of SO₃.

At equilibrium the rate of the forward reaction is always equal to the rate of the backward reaction. The concentration of the reactants and products do not change with time at equilibrium.

The rate of decomposition of SO₃ at equilibrium is equal to the rate of formation of SO₃. At equilibrium the concentration of SO₃ will remain constant.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of
lianna [129]

Answer:

DECREASE BY A FACTOR OF FOUR

Explanation:

Using pressure equation:

P 1 / T1 = P2 /T2     (at constant volume)

P1 = P

T1 =T

P2 = ?

T2 = 4 T

So therefore;

P2 = P1T1/ T2

P2 = P T/ 4 T

P2 = 1/4 P

The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.

Compound AB decomposes into elements A and B by the following reaction: AB →A + B. If you produce 10.00 g of B and 3.00 g of A,
zavuch27 [327]

Answer:

13.00 g

Explanation:

To solve this problem, you need to understand the law of conservation of mass.  This law means that whatever amount you start out with is what you should have at the end.  The amount may be in different forms, but that amount is still there.

If you produced 10.00 g of B and 3.00 g of A, you should have started out with 13.00 g of AB.

10.00 + 3.00 = 13.00

When an electron in an atom absorbed a photon, the energy of the electron changed by 2.94 x 10-19 J. What is the frequency of th
jok3333 [9.3K]

When an electron in an atom absorbed a photon, the energy of the electron changed by 2.94 × 10⁻¹⁹. The frequency of the photon is 4.4 × 10¹⁴ Hertz .

<h3>How to calculate the frequency of photon ?</h3>

To calculate the frequency of photon use the expression

E = hv

where,

E = Energy

h = Planck's Constant

v = frequency (Hz)

Put the value in above formula we get

E = hv

2.94 × 10⁻¹⁹ = 6.6 × 10⁻³⁴ × v

v = \frac{2.94 \times 10^{-19}\ J}{6.6 \times 10^{-34}}

  = 0.44 × 10¹⁵

  = 4.4 × 10¹⁴

Thus from the above conclusion we can say that When an electron in an atom absorbed a photon, the energy of the electron changed by 2.94 × 10⁻¹⁹. The frequency of the photon is 4.4 × 10¹⁴ Hertz .

1. How many moles of Cu are in 1.48 × 1025 Cu atoms?
morpeh [17]
1 mole ------------- 6.02 x 10²³ atoms
( moles Cu) ------- 1.48 x 10²⁵ atoms

moles Cu =  ( 1.48 x 10²⁵ ) x 1 / 6.02 x 10²³

moles Cu = 1.48 x 10²⁵ / 6.02 x 10²³

=<span> 24.58 moles of Cu</span>
