Answer:
<span>ideally follow Raoult's law</span>

Explanation:
Raoult's law states that: "<span>the partial </span>vapor pressure<span> of each component of an </span>ideal mixture<span> of liquids is equal to the vapor pressure of the pure component multiplied by its </span>mole fraction<span> in the mixture"
</span>
It is given that:
1- the two solutions are similar
2- <span>their interactions together are the same as in the individual liquids

This means that the solution formed will be an ideal solution. This means that the vapor pressure formed will be exactly equal to that predicted by Raoult's law.

Hope this helps :)</span>

The elementary reaction 2H20(g)&lt;---&gt;2H2(g)+O2(g) proceeds at a certain temperature until the partial pressures of H2O, H2,
olya-2409 [2.1K]

Answer:

4.9 x 10⁻⁶.

Explanation:

  • For the reaction:

<em>2H₂O(g) ⇄ 2H₂(g) + O₂(g),</em>

'

P of H₂ = 0.002 atm, P of O₂ = 0.006 atm, and P of H₂O = 0.07 atm.

∴ The equilibrium constant (Kp) = (P of H₂)²(P of O₂)/(P of H₂O)² = (0.002 atm)²(0.006 atm)/(0.07 atm)² = 4.9 x 10⁻⁶.

One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin c, c6h8o6). given that one cup
kodGreya [7K]
The question is incomplete. Complete question is read as:
'<span>One cup of fresh orange juice contains 115 mg of ascorbic acid (vitamin C, C6H8O6). Given that one cup = 218.0 mL calculate the molarity of vitamin C in organic juice.'
..........................................................................................................................
Answer:
Given: weight of solute (ascorbic acid) = 115 mg = 0.115 g
Volume of solution = 218.0 mL = 0.218 L
Molecular weight of ascorbic acid = 176.12 g/mol.

Now, Molarity = </span>\frac{\text{weight of solute(g)}}{\text{Molecular weight X Vol. of solution(l)}}
                       = \frac{\text{0.115}}{\text{176.12 X 0.218}}
<span>                       = 0.002995 mol/dm3

Answer: Molarity of solution = </span>0.002995 mol/dm3<span>

9. For each reaction listed, identify the proton donor (or acid) and the proton acceptor(or base).
Talja [164]

Answer:

Explanation:

conjugate acid, based on Brønsted–Lowry acid–base theory, is a chemical compound that is formed by the reception of a proton by a base

a. CH₃COOH + H₂O ⇌ H₃0⁺ + CH₃C00-

Acid <> CH₃COOH

Base <> H₂O

Conjugate acid <> H₃0 +

Conjugate base <>CH₃C00-

b. HCO₃ + H₂O ⇌ H₂CO₃⁻ + OH⁻

Acid <> H₂O

Base <> HCO₃

Conjugate acid <> H₂CO₃⁻

Conjugate base <>OH⁻

C. HNO₃ + SO₄²⁻ ⇌ HSO₄⁻ + NO₃⁻

Acid <>HNO₃

Base <>SO₄²⁻

Conjugate acid <>HSO₄⁻

Conjugate base <>NO₃⁻

A Bronsted acid is reffered to as a proton donor while a Bronsted base is a proton acceptor
