Answer:

A. Acidic

B. Neutral

C. Basic

D. Acidic

E. Basic

Explanation:

The reaction of salts with water to give aqueous solutions which are either acidic, basic or neutral is known as salt hydrolysis. Salts that are produced from the reaction of strong acids and weak bases give acidic solutions. Salts that are produced the reaction between weak acids and strong bases give basic solutions. Neutral solutions are obtained from salts produced bynthe reaction of strong acids and strong bases.

The hydrolysis of the given salts are shown below:

A. AlCl₃ + 3 H₂O ---> 3 HCl + Al(OH)₃

The aqueous solution produced will be acidic since HCl is a strong acid while Al(OH)₃ is a weak base.

B. NaBr + H₂O ----> HBr + NaOH

The aqueous solution produced will be neutral since HBr is a strong acid and NaOH is strong base as well.

C. NaClO + H₂O ----> HClO + NaOH

The aqueous solution produced will be basic since HClO is a weak acid while NaOH is a strong base.

D. CH₃NH₃NO₃ + H₂O ----> HNO₃ + CH₃NH₂ + H₂O

The aqueous solution produced will be acidic since HNO₃ is a strong acid while CH₃NH₂ is a weak base.

E. Na₂SO₃ + 2 H₂O ----> H₂SO₃ + 2 NaOH

The aqueous solution produced will be basic since H₂SO₃ is a weak acid while NaOH is a strong base.

densk [106]

Answer:

Q sln = 75.165 J

Explanation:

a constant pressure calorimeter:

Q sln = mCΔT

∴ m sln = m Ba(OH)2 + m HCl

∴ molar mass Ba(OH)2 = 171.34 g/mol

∴ mol Ba(OH)2 = (0.06 L)(0.3 mol/L) = 0.018 mol

⇒ mass Ba(OH)2 = (0.018 mol)(171.34 g/mol) = 3.084 g

∴ molar mass HCl = 36.46 g/mol

∴ mol HCl = (0.06 L)(0.60 mol/L) = 0.036 mol

⇒ mass HCl = (0.036 mol)(36.46 g/mol) = 1.313 g

⇒ m sln = 3.084 g + 1.313 g = 4.3966 g

specific heat (C):

∴ C sln = C H2O = 4.18 J/g°C

∴ ΔT = 26.83°C - 22.74°C = 4.09°C

heat absorbed (Q):

⇒ Q sln = (4.3966 g)(4.18 J/g°C)(4.09°C)

⇒ Q sln = 75.165 J

How does newton’s third law effect bowling?

Misha Larkins [42]

Answer:

The bowling ball will remain in motion until an unbalanced force acts on the bowling ball. ... When the ball hits the pins, they push on the ball with the same amount of force in the opposite direction. This means that the ball will slow down, and the pins will fall, which is the reaction.

A solution contains 15 grams of salt per litter of solution. How many grams of salt are in 3.3 litters of solution?

Verizon [17]

49.5g

Explanation:

Mass of salt = 15g

Volume of solution = 1L

Volume of given solution = 3.3L

Unknown:

Mass of salt in the solution = ?

Solution:

Since we have been given the concentration of the salt in the solution, we can use it to solve the problem.

Concentration; 15g/L

Given;

In 1L of the solution we have 15g of salt,

In 3.3L of the solution we will have 3.3 x 15 = 49.5g

The salt is the solute and it represents the dissolved substances.
