Answer:

H2O2 + Fe2+ 2H+ = Fe3+ + 2H2O

Explanation:

H2O2 is reduced to H2O and Fe2+ is oxidized to Fe3+

Answer:

1,239,284pa

Explanation:

Assuming it's an ideal gas we use

PV=nRT

P=nRT/V

then we convert our Temperature into Kelvin

T=25+273.15 =298.12K

we convert our volume into M cubed

1.5L =0.0015 cubic meter

P=nRT/V

P= (0.75×298.12×8.314)/0.0015

P = 1,239,284pa

Calculate the percent ionization of 1.55 m aqueous acetic acid solution. for acetic acid, ka=1.8⋅10−5.

Fittoniya [83]

Answer is: <span>percent ionization of aqueous acetic acid solution is 0.341%.
c(CH</span>₃COOH) = 1.55 M.
Ka(CH₃COOH) = 1.8·10⁻⁵.
Chemical reaction: CH₃COOH ⇄ CH₃COO⁻ + H⁺.
[CH₃COO⁻] = [H⁺] = x.
[CH₃COOH] = 1.55 M - x.
Ka = [CH₃COO⁻] · [H⁺] / [CH₃COOH].
1.8·10⁻⁵ = x² / (1.55 M - x).
Solve quadratic equation: x = 0.0053 M.
percent of ionization:
α = 0,0053 M ÷ 1.55 M · 100% = 0,341%

What substance is acting as the Brønsted-Lowry base in the forward reaction below? H2O + HCI ----> H3O+ CI-

yarga [219]

H2O is the Bronsted-Lowry base because it accepts the hydrogen ion to become H3O after the reaction is complete.

The chemical formula of ordinary sugar is C12H22O11. Calculate the mass of 7.35 mol of sugar.

ch4aika [34]

First, you need to find the mass of 1 mol of sugar. Mass, or molar mass, can simply be found by adding the masses of the individual elements. These are given to you on the periodic table.

$C_{12}H_{22}O_{11}$

12 x 12.011 grams (molar mass of Carbon) = 144.132 g

22 x 1.008 grams (molar mass of Hydrogen) = 22.176 g

11 x 15.999 grams (molar mass of Oxygen) = 175.989 g

Add all of the pieces together.

144.132 g + 22.176 g + 175.989 g = 342.297 grams

So, if one mole has 342.297 grams, then 7.35 of that amount will be your answer.

342.297 g/mol x 7.35 mol = 2,515.88 grams
