Answer: Option (b) is the correct answer.

Explanation:

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.

For example,   CaCO_{3}(s) + CO_{2}(aq) + H_{2}O(l) \rightleftharpoons Ca^{2+}(aq) + 2HCO^{-}_{3}(aq)

Hence, expression for equilibrium constant will be as follows.

        K_{eq} = \frac{[Ca^{2+}][HCO^{-}_{3}]^{2}}{[CO_{2}][H_{2}O]}

Since, the concentration for a solid substance is considered as 1 or unity. Therefore, adding or removing a solid will not affect the equilibrium.

Thus, we can conclude that according to Le Châtelier’s Principle, the amount of solid reactant or product present does not have an impact on the equilibrium because the solid does not appear in the equilibrium constant, so adding or removing solid has no effect.

For a half-reaction in an acidic solution, which substances should you add to balance the equation?
Alla [95]
The answer is a. H+ and H2O. For a half-reaction in acidic solutions, elements that are not hydrogen and oxygen are balanced first. Then we add H2O to balance oxygen atoms and we add H+ to balance the hydrogen atoms. We do the same steps for basic solutions, but we also add hydroxide ions OH- in the latter part.

irinina [24]

In a double decomposition reaction, AgNo3 and NaCl combine to form NaNo3 and AgCl. The resulting AgCl precipitate is white as well. AgCl (silver chloride) with nitrate of sodium. It will be an insoluble solid, AgCl. The equation represents a double decomposition reaction. Therefore, option B is correct.

<h3>What is double decomposition reaction ?</h3>

A type of decomposition reaction known as a double decomposition reaction involves the exchange of positive and negative ions between two constituent reactants to create two new molecules.

When two compounds in a solution react to generate two new compounds through the exchange of radicals, this reaction is known as a double displacement reaction. Double decomposition reaction is another name for this kind of reaction.

Thus, option B is correct.

Can you calculate the energy needed to increase the temperature of 100kg of iron by 40°C?
VLD [36.1K]

Answer: 177600 J or 177.6kJ

Explanation:

For this problem, we need to use q = mcAT

we have m = 10000, and AT= 40. The specific heat of iron is 0.444.

So now we can plug it in: q = 10000*.444*40 = 177600 J or 177.6kJ

1. Determine the number of atoms in 4.64 g gold.
liubo4ka [24]

Answer:

The answer to your question is below

Explanation:

1.-

a) Look for the mass number of Gold in the periodic table

Mass number = 197 g

Use proportions to answer this question

                          197 g of gold ------------- 6.023 x 10 ²³ atoms

                            4.64 g of gold ----------  x

                            x = (4.64 x 6.023 x 10²³) / 197

                           x = 1.42 x 10²² atoms

2.- mass of 4.12 x 10²⁴ molecules of glucose

Molecular mass = (6 x 12) + (12 X 1) + (6 x 16)

                          = 72 + 12 + 96

                          = 180 g

             180 g of glucose ------------------- 6.023 x 10 ²³ molecules

                x                        -------------------  4.12 x 10 ²⁴ molecules

                x = (4.12 x 10²⁴ x 180) / 6.023 x 10²³

               x = 1231.3 g of glucose
