What stress will shift the following equilibrium system to the left? 2SO2(g) + O2(g) ⇌ 2SO3(g); ΔH= –98.8 kJ/mol

Answer:

The stress that will shift the equilibrium system to the right is decreasing the temperature

Explanation:

Chemical equilibrium

This is a state where there is no observable changes in the properties of the system with time.

From the above, a French scientist establishes a principle which states that when an external constraints such as change in temperature, pressure and concentration is imposed on a system in equilibrium, the equilibrium will shift to neutralise the effect.

Furthermore, the principle explained that:

An increase in temperature of an exothermic reaction (i.e ΔH= –ve) will shift the equilibrium backward.

A decrease in temperature of an exothermic reaction (i.e ΔH= –ve) will shift the equilibrium forward.

An increase in temperature of an endothermic reaction (i.e ΔH= +ve) will shift the equilibrium forward.

A decrease in temperature of an exothermic reaction (i.e ΔH= +ve) will shift the equilibrium back.

How to determine which stress that will shift the equilibrium forward (right)

2SO₂(g) + O₂(g) ⇌ 2SO₃(g); ΔH= –98.8 KJ/mol

From the equation above, we can see that the reaction is exothermic reaction (i.e ΔH= –ve).

Therefore, decreasing the temperature will shift the equilibrium to the right.

Llana [10]

Answer:

I'm feeling nice today so heres the answer

Explanation:

In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.

Explanation:

Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.

The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.

The other options presented are not correct, because

Respiration is a process that occurs in the mitochondria.

Diffusion is a passive transport process that does not require energy.

Cellular recognition depends on membrane proteins that act as specific receptors.

Consider the equation: 2NO2(g) N2O4(g). Using ONLY the information given by the equation which of the following changes would in
Reika [66]
I believe the correct answer is the first option. To increase the molar concentration of the product N2O4, you should increase the pressure of the system. You cannot determine the effect of changing the temperature since we cannot tell whether it is an endothermic or an exothermic reaction. Also, decreasing the number of NO2 would not increase the product rather it would shift the equilibrium to the left forming more reactants. The only parameter we can change would be the pressure. And, since NO2 takes up more space than the product increasing the pressure would allow the reactant to collide more forming the product.

How many grams in 6.20 x 10^25 atoms of bromine (Br) ? image attached , will give brainliest
Deffense [45]

Answer:

8239.2g

Explanation:

Given parameters:

Number of atoms in Br  = 6.2 x 10²⁵atoms

Unknown:

Mass of Br = ?

Solution:

From mole concepts, we know that:

       1 mole of a substance contains 6.02 x 10²³ atoms/mol

 Molar mass of Br  = 80g/mol

6.2 x 10²⁵atoms  x \frac{1}{6.02 x 10^{23} } \frac{mol}{atoms} x  80 x \frac{g}{moles}  

          = 8239.2g

A 35.66g sample of copper is heated using 600j of energy. if the original temperature of the copper is 85C what is its final tem
ira [324]

This problem is providing the mass, energy, initial temperature and specific heat of a sample of copper that is required to calculate the final temperature.

Thus, we recall the general heat equation:

Q=mC(T_f-T_i)\\

Which has to be solved for the final temperature, T_f as follows:

T_f=T_i+\frac{Q}{mC}

Finally, we plug in the numbers to obtain:

T_f=85\°C+\frac{600J}{35.66g*0.38\frac{J}{g\°C} } \\\\T_f=129.3\°C

However, this result is not given in the choices.
