Answer:

108.32

Explanation:

dalton's law

Pgas1 = x1 * Ptotal

Pgas1 = (mole fraction of a gas) * Ptotal

Ptotal = (mole fraction of a gas) ÷ Pgas1

1 torr = 0.133 kpa kilopascal

Answer:

A. 2H₂O₂ → 2H₂O + O₂

Explanation:

1. H₂O₂ + I⁻ → H₂O + OI⁻

2. H₂O₂ + OI⁻ → H₂O + O₂ + I⁻

If we <u>make a net sum of both reactions</u>, we're left with:

H₂O₂ + I⁻ + H₂O₂ + OI⁻ → H₂O + OI⁻ + H₂O + O₂ + I⁻

Grouping species:

2H₂O₂ + OI⁻ + I⁻ → 2H₂O + OI⁻ + O₂ + I⁻

There is OI⁻ at both sides, so it is eliminated -same goes for the catalyst, I⁻-.

2H₂O₂ → 2H₂O + O₂

Thus the answer is option A.

Consider two different ions. The anion has a valence of -2. The cation has a valence of +2. The two ions are separated by a dist

strojnjashka [21]

Answer:

Force of attraction = 35.96 $\times 10^{27}$ N

Explanation:

Given: charge on anion = -2

Charge on cation = +2

Distance = 1 nm = $10^{-9}$ m

To calculate: Force of attraction.

Solution: The force of attraction is calculated by using equation,

$F = \dfrac{k \times q_1 q_2}{ \r^2}$ ---(1)

where, q represents the charge and the subscripts 1 and 2 represents cation and anion.

k = $8.99 \times 10^9 \ Nm^{2}C^{-2}$

F = force of attraction

r = distance between ions.

Substituting all the values in the equation (1) the equation becomes

$F = \dfrac{8.99 \times 10^9 \times 2 \times 2}{ \left ( 10^-9 \right )^2 }$

Force of attraction = 35.96 $\times 10^{27}$ N
