What is the difference between a neutralization reaction and a double-displacement reaction? select one:

1 answer:

3 0

I believe the correct answer is option C. The difference between a neutralization reaction and a double-displacement reaction would be that neutralization reactions always produce water and a salt. Double displacement reaction is a reaction that involves reaction of two compounds where the cations and the anions of the reactants would switch places producing new compounds. Neutralization reaction, on the other hand, always involve the reaction of an acid and a base forming a salt and water. Example of a double displacement reaction would be 2BaCl + Na2SO4 = Ba2SO4 + 2NaCl. An example of a neutralization reaction would be HCl + NaOH = NaCl + H2O.

2. It is used to soften hard water

3. it is used to standardize acids in the laboratory

Uses of Sodium sulphate

1. It is used in the manufacture of detergents and glass

2. It is used as a purgative

3. It is used to treat wood-pulp for paper making.

Uses of Potassium nitrate

1. It is used in making gunpowder

2. It is used as rocket propellant

3. It is used in making fertilizer

Uses of Potassium chlorate

1. It is used as an oxidizer

2. It is used in making explosives

3. it is used as a disinfectant

Uses of Potassium permanganate (vii)

1. It is used as an oxidizing agent

2. It is used as a disinfectant

3. It is used as an analytical reagent

Uses of Potassium chloride

1. It is used for the manufacture of fertilizer

2. It is used as an alternative salt to sodium chloride

3. It is used in medicine to treat low blood pressure

2. Potassium nitrate and potassium chloride are used in the manufacture of fertilizers.

Potassium nitrate is used in fertilizers because it provides two important plant nutrients, nitrogen and potassium to plants.

Potassium chloride (potash) is used in fertilizers because it efficiently deliver the important plant nutrient, potassium, to plants.

How many grams of CaCl2 are in 250 mL of 2.0 M CaCl2?

Tom [10]

The answer is: " 56 g CaCl₂ " .
__________________________________________________________

Explanation:
__________________________________________________________
2.0 M CaCl₂ = 2.0 mol CaCl₂ / L ;

Since: "M" = "Molarity" (measurement of concentration);

= moles of solute per L {"Liter"} of solution.
__________________________________________________________
Note the exact conversion: 1000 mL = 1 L .

Given: 250 mL ;

250 mL = ? L ? ;

250 mL * (1 L / 1000 L) = (250/1000) L = 0.25 L .
___________________________________________________________

(2.0 mol CaCl₂ / L ) * (0.25L) = (2.0) * (0.25) mol = 0.50 mol CaCl₂ ;

We have: 0.50 mol CaCl₂ ; Convert to "g" (grams):

→ 0.50 mol CaCl₂ .
___________________________________________________________
1 mol CaCl₂ = ? g ?

From the Periodic Table of Elements:

1 mol Ca = 40.08 g

1 mol Cl = 35.45 g .

There are 2 atoms of Cl in " CaCl₂ " ;

→ Note the subscript, "2", in the " Cl₂ " ;
__________________________________________________________
So, to calculate the molar mass of "CaCl₂" :

40.08 g + 2(35.45 g) =

40.08 g + 70.90 g = 110.98 g ; round to 4 significant figures;

→ round to 111 g/mol .
__________________________________________________________
So:

→ 0.50 mol CaCl₂ = ? g CaCl₂ ? ;

→ 0.50 mol CaCl₂ * (111 g CaCl₂ / mol CaCl₂) ;

= (0.50) * (111 g) CaCl₂ ;

= 55.5 g CaCl₂ ;

 → round to 2 significant figures;

 → 56 g CaCl₂ .
___________________________________________________________
The answer is: " 56 g CaCl₂ " .
___________________________________________________________

Wine goes bad soon after opening because the ethanol in it reacts with oxygen gas from the air to form water and acetic acid , t

ryzh [129]

The mass of ethanol is consumed by the reaction of 3.37g oxygen gas is 4.85g

Explanation:

The balanced equation for the chemical reactions is;

CH₃CH₂OH + O₂ → CH₃COOH + H₂O

The mole ratio between oxygen and ethanol in the reaction is 1 : 1

The molar mass of O₂ is 32g / mole. Therefore the O₂ moles consumes in the reaction is;

3.37 / 32

If the molar mass of ethanol is 46.07g/mole, and the ration of reaction in 1 : 1; Then the moles of ethanol consumed is;

3.37/32 * 46.07

= 4.85g
