Answer: Dissolve approximately 3 mg of Sodium Chloride in 2 mL of water.

Add 0.4 mL of silver nitrate TS and acidify with diluted nitric acid.

For the pH of a solution prepared by dissolving 0. 350 mol of solid methylamine hydrochloride, the pH is mathematically given as

pH = 11.14

Generally, the equation for the pKb  is mathematically given as

pKb = -logKb

Therefore

pKb of CH3NH2 = -log(4.40×10-4)

pKb of CH3NH2= 3.36

Hence

pKa= 14 - pKb

pKa= 14 - 3.36

pKa= 10.64

In conclusion, using

pH = pKa + log([A-]/[HA])

pH = 10.64 + log(1.10M/0.350M)

pH = 11.14

Answer:

12 H, 18 O, 6 C

Explanation:

[tex]6H_{2} O + 6CO_{2} -- > C_{6}H_{12} + 6O_{2}\\[/tex]

___________________

first, we'll fo the h on the first equation: [tex]6H_{2}[/tex]

multiply the 6 and 2 to get twelve.

in the second equation, we see that there is [tex]H_{12}[/tex]

so, in both there are 12 H.

__________________

Now we'll do O.

in the first equation we have [tex]6O + 6O_{2}[/tex]

so we have 6 + (6*2) or 6 + 12, which gives us 18

in the second equation we have [tex]O_{6} + 6O_{2}[/tex]

it's basically the same thing, just written differently, so we have 18.

__________________

Finally, C.

In the first equation, we have [tex]6C[/tex]

in the second [tex]C_{6}[/tex], again, same thing expressed differently.

both have 6 C.

The number of moles of oxygen required to generate 28 moles of water from the reaction is 14 moles

2H₂ + O₂ —> 2H₂O

From the balanced equation above,

2 moles of water were obtained from 1 mole of oxygen

From the balanced equation above,

2 moles of water were obtained from 1 mole of oxygen

Therefore,

28 moles of water will be obtained from = 28 / 2 = 14 moles of oxygen

Thus, 14 moles of oxygen are needed for the reaction

The balanced equation which have the coefficient 3 in front of any of the reactants is 3H₂SO₄ + 2B(OH)₃ → B₂(SO₄)₃ + 3H₂O.

Those chemical equations in which number of each atoms pesent in reactant side as well as on product side is always equal to each other.

Let us consider the balanced equations for the given chemical reactions are:

Balanced form of the above reaction will be written as Zn+2HCl → ZnCl₂+H₂ where all atoms are present in equal quantity.

Balanced form of the given reaction will be written as 3H₂SO₄ + 2B(OH)₃ → B₂(SO₄)₃ + 3H₂O, where coefficient 3 is present in before sulphuric acid and water molecule.

Balanced form of above reation will be written as Fe+ 2AgNO₃ → Fe(NO₃)₂ + 2Ag.

Balnced form of above chemical equation will be represented as C₂H₄O₂ + 2O₂ → 2CO₂ + 2H₂O, and coefficient 3 is not used any where.

Answer: 0.759 L

Explanation:

molarity = moles of solute / liters of solution

so, 6.750 = 5.120 / liters of solution

liters of solution = 5.120/6.750 = 0.759 L

The mass of the precipitate, BaSO₄ obtained from the given reaction is 18.64 grams

Mole = Molarity x Volume

Mole of Na₂SO₄ = 0.3 × 0.3

Mole of Na₂SO₄ = 0.09 mole

Mole = Molarity x Volume

Mole of BaCl₂ = 0.4 × 0.2

Mole of BaCl₂ = 0.08 mole

Balanced equation

Na₂SO₄(aq) + BaCl₂(aq) —> BaSO₄(s) + 2NaCl(aq)

From the balanced equation above,

1 mole of BaCl₂ reacted with 1 mole of Na₂SO₄.

Therefore,

0.08 mole of BaCl₂ will also react with 0.08 mole of Na₂SO₄.

From the above illustration, we can see that only 0.08 mole of Na₂SO₄ out of 0.09 mole given is neede to react completely with 0.08 mole of BaCl₂.

Therefore, BaCl₂ is the limiting reactant

Balanced equation

Na₂SO₄(aq) + BaCl₂(aq) —> BaSO₄(s) + 2NaCl(aq)

From the balanced equation above,

1 mole of BaCl₂ reacted to produce 1 mole of BaSO₄.

Therefore,

0.08 mole of BaCl₂ will also react to produce 0.08 mole of BaSO₄.

The mass of BaSO₄ can be obtained as follow

Mass = mole × molar mass

Mass of BaSO₄ = 0.08 × 233

Mass of BaSO₄ = 18.64 g
