The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing

Answer: Option (c) is the correct answer.

Explanation:

When we crush a solute then there will be increase in number of solute particles. This means that there is increase in surface area of solute particles.

Hence, more is the surface area of solute particles more will be the collisions between solute and solvent particles. Therefore, more will be rate of reaction.

Thus, we can conclude that we crush solids before putting them into a solvent to increase the surface area of the solute.

What is the molarity of a solution in
lana66690 [7]

Answer:

1.52M in NaCl

Explanation:

Molarity = moles solute / volume solution in Liters

=> molarity (M) = 3.8 moles / 2.5 Liters solution = 1.52 molar solution in NaCl

2. What are the characteristics of an acid (at least 3)?
arlik [135]

Answer:Acids taste sour, react with metals, react with carbonates, and turn blue litmus paper red. Bases taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue.

Explanation:

  • Sour taste (though you should never use this characteristic to identify an acid in the lab)
  • Reacts with a metal to form hydrogen gas.
  • Increases the H+ concentration in water.

If anyone could please help me with this i'd really appreciate it!
faltersainse [42]

Answer:

The answer to your question is:  0.0265 moles of H3PO4    

Explanation:

Data

[H3PO4] = ?

Volume Ba(OH)2= 0.186 l

[Ba(OH)2] = 0.214 M

Equation

                 2H3PO4 (aq) + 3 Ba(OH)2 (aq) ---> 6H2O (l) + Ba3(PO4)2 (s)

Process

Molarity = moles / volume

moles = Molarity x volume

moles of Ba(OH)2 = 0.214 x 0.186

                             = 0.0398

Rule of three

        2 moles of H3PO4 --------------------  3 moles of Ba(OH)2

        x                              --------------------   0.0398 moles of Ba(OH)2

                  x = (0.0398 x 2) / 3

                 x =  0.0265 moles of H3PO4

Consider the reaction: C(s) + O2(g)CO2(g) Write the equilibrium constant for this reaction in terms of the equilibrium constants
jek_recluse [69]

Answer:

A. Ka = [CO2] / [C] [O2]^1/2

B. Kb = [CO2] / [CO] [O2]^1/2

Explanation:

Equilibrium constant is simply defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.

Now, we shall obtain the expression for the equilibrium constant for the reaction as follow:

A. Determination of the expression for equilibrium constant Ka.

This is illustrated below:

C(s) + 1/2 O2(g) <==> CO(g)

Ka = [CO2] / [C] [O2]^1/2

B. Determination of the expression for equilibrium constant Kb.

This is illustrated below:

CO(g) + 1/2 O2(g) <==> CO2(g)

Kb = [CO2] / [CO] [O2]^1/2
