Which situation would not cause the following equilibrium to shift to the right

1 answer:

3 0

If you’re talking about a reaction, an increase in the products (values on the right side of the chemical equation) would cause the reaction to shift left instead of right. Also a decrease in the reactants.

Also, could be wrong, but increasing the volume/ decreasing the pressure on the reactant side will cause the reaction to shift left

A wave is moving towards shore with a velocity of 5.0 MS if it’s frequency is 2.5 Herz what is the wave length

EastWind [94]

Answer:

Explanation:

The wavelength of a wave can be found by using the formula

$\lambda = \frac{c}{f} \\$

where

c is the speed of the wave

f is the frequency

From the question

c = 5 m/s

f = 2.5 Hz

We have

$\lambda = \frac{5}{2.5} = 2 \\$

We have the final answer as

Hope this helps you

How many moles of steric acid are contained in 0.25 ml of a hexane solution containing 5.4 x 10^-4 g stearic acid/l?

san4es73 [151]

First, we determine the mass of stearic acid in the solution by multiplying the given concentration by the volume.
mass of stearic acid = (5.4 x 10^-4 g/L) (0.25 mL) (1000 mL/1L)
= 0.135 g
Then, we divide this amount by the molar mass in order to obtain the number of moles of stearic acid. The molar mass of stearic acid is 284.4772 g/mol.
moles stearic acid = 0.135 g / (284.4772 g/mol)
= <em>4.75 x 10^-4 mol</em>

A student reacted NiS2 (MM = 122.83 g/mol) with O2 (MM=32.00 g/mol) to make SO2 (MM=64.07 g/mol) according to this balanced equa

Mice21 [21]

Answer:

Theoretical yield of SO₂ is 1.56 × 10² g

Explanation:

Given data:

Mass of NiS₂ = 1.50 ×10² g

Mass of O₂ = 2.420 ×10² g

Theoretical yield of SO₂ = ?

Solution:

Chemical equation:

2NiS₂ + 5O₂ → 2NiO + 4SO₂

Moles of NiS₂:

Number of moles = mass/ molar mass

Number of moles = 1.50 ×10² g / 122.83 g/mol

Number of moles = 1.22 mol

Moles of O₂:

Number of moles = mass/ molar mass

Number of moles = 2.420 ×10² g / 32 g/mol

Number of moles = 7.56 mol

Now we compare the moles of SO₂ with NiS₂ and O₂.

NiS₂ : SO₂

2 : 4

1.22 : 4/2×1.22 = 2.44

O₂ : SO₂

5 : 4

7.56 : 4/5×7.56 =6.05

Moles of SO₂ produced by NiS₂ are less it will limiting reactant.

Mass of SO₂ = moles × molar mass

Mass of SO₂ = 2.44 mol × 64.07 g/mol

Mass of SO₂ = 156.33 g

So theoretical yield of SO₂ is 1.56 × 10² g

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.

likoan [24]

Given :

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.

To Find :

The volume of the gas after it is heated.

Solution :

Since, their is no information about pressure in the question statement let us assume that pressure is constant.

Now, we know by ideal gas equation at constant pressure :

$\dfrac{V_1}{V_2} = \dfrac{T_1}{T_2}\\\\\dfrac{3.82}{V_2}= \dfrac{204.9}{304.8}\\\\V_2 = \dfrac{304.8}{204.9} \times 3.82\\\\V_2 = 5.68 \ L$

Hence, this is the required solution.
