Chemical equation reaction between h2co3 and ba(oh)2

The moles of aluminum sulfate that could be produced from 32.7 grams of aluminum nitrate is 0.07 moles.

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

W = given mass of aluminum nitrate = 32.7g

M = molar mass of aluminum nitrate = 213 g/mol

Moles of aluminum nitrate = 32.7 / 213 = 0.154 mol

Given chemical reaction is:

3Na₂SO₄(aq) + 2Al(NO₃)₃(aq) → Al₂(SO₄)₃(s) + 6NaNO₃(aq)

From the stoichiometry of the reaction it s clear that,

2 mole of Al(NO₃)₃ = produces 1 mole of Al₂(SO₄)₃

0.154 mole of Al(NO₃)₃ = produces (1/2)(0.154)=0.07 mole of Al₂(SO₄)₃

Hence produced moles of aluminum sulfate is 0.07 moles.

Answer:

acidic

Explanation:

The HC2O−4 ion is amphiprotic.

As an acid, it has the given Ka2 of HC2O−4 is 6.1 × 10^−5.

To find the Kb, use the relationship between Ka1 and Kb for the conjugate acid of a base.

The Kb of HC2O−4 is 1.0 × 10^−14 / 5.9 × 10^−2 ≈ 1.7 × 10^−13.

In mechanics, speed increase is the pace of progress of the speed of an article regarding time (acceleration). Speed increases are vector amounts (in that they have greatness and direction). The direction of an item's speed increase is given by the direction of the net power following up on that article. The size of an item's speed increase, as depicted by Newton's Second Law, is the consolidated impact of two causes:

the net equilibrium of all outer powers acting onto that item — size is straightforwardly relative to this net coming about force;

The answer is 4.9 moles of salt will be needed to add to 1 kg of water to change the boiling point by 5 °C.

Boiling point elevation is the phenomenon that occurs when the boiling point of a liquid (a solvent) is increased when another compound is added, such that the solution has a higher boiling point than the pure solvent.

Boiling point elevation occurs whenever a non-volatile solute is added to a pure solvent.

ΔT = i * Kb * m

where m, Kb and i are the molality of solution, ebullioscopic constant and Van't Hoff factor respectively

The data given in the question is ΔT = 5 °C

mass of solvent = 1 kg

Kb = 0.51 °C/(mol/kg)

Van't Hoff Factor for NaCl is 2

Substituting the values in the above equation

[tex]\rm 5 = \rm\dfrac{2\times0.51\times moles \;of \;salt}{1}[/tex]

[tex]\rm moles \;of \;salt = \rm\dfrac{5}{2\times0.51}[/tex]

moles of salt = 4.9

Therefore 4.9 moles of salt will be needed to add to 1 kg of water to change the boiling point by 5 °C.

Answer:

A

Explanation:

The following statements is not true for Coulomb's law is:

A. The force will decrease if the distance is decreased.

Coulomb's law describes the electrostatic force between two point charges. The law states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.

Mathematically, Coulomb's law is expressed as:

F = k * (|q1| * |q2|) / r²

Where:

F is the electrostatic force between the two charges q1 and q2.

k is Coulomb's constant, a proportionality constant with a value of approximately 8.99 x 10⁹ N m²/C² in a vacuum.

|q1| and |q2| are the magnitudes (absolute values) of the two charges.

r is the distance between the two charges.

Now let's analyze statement A:

A. The force will decrease if the distance is decreased.

This statement is incorrect. According to Coulomb's law, as the distance (r) between the two charges decreases, the force (F) between them increases. The force is inversely proportional to the square of the distance (r²). As the distance becomes smaller, the denominator of the Coulomb's law expression (r²) decreases, causing the force to increase.

Conversely, if the distance between the charges increases, the force between them decreases. The force decreases with the square of the distance.
