Hello!

The answer is 1.2kg.

1000g=1kg

To convert to kg:

Divide by 1000.

1,151g/1000g=1.151kg

Round to the nearest tenth to get 1.2kg.

I hope this helps!

<h2>Acetic Acid</h2>

Explanation:

  • Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
  • Methanol in presence of CO_2 and hydrogen gas gets oxidized to acetic acid with the release of water.

Hence, compound A will be Acetic acid.

CH_3OH + CO_2 +H_2 → CH_3COOH + H_2O

  • The acetic acid formed can be transformed into -
  1. CH_3COOH → CH_4 + CO

        The product formed is methane and carbon monoxide.

    2. CH_3COOH → CH_2CHO + H_2O

         The product formed is formaldehyde and water.

    3. CH_3COOH + NaHCO_3 → CH_3COONa +CO_2 +H_2O

         The product formed is sodium acetate, carbon dioxide, and water.

liquid octane(CH3)(CH2)6CH3) reacts with gaseous oxygen gas(O2) to produce gaseous carbon dioxide(CO2) and gaseous water(H2O). I
max2010maxim [7]

The percent yield of carbon dioxide will be 49.0 %.

<h3>Percent yield</h3>

First, let's look at the equation of the reaction:

2C_8H_1_8 + 25O_2 -- > 16CO_2 + 18H_2O

The mole ratio of octane to oxygen is 2:25.

Mole of 3.43 g octane = 3.43/114.23 = 0.03 mol

Mole of 19.1 g oxygen = 19.1/32 = 0.60 mol

Thus, octane is limiting.

Mole ratio of octane to carbon dioxide = 2:16.

Equivalent mole of carbon dioxide = 0.03 x 8 = 0.24 mol

Mass of 0.24 mol carbon dioxide = 0.24 x 44.01 = 10.5624 grams

Percent yield of carbon dioxide = 5.18/10.5624 = 49.0 %

What is the solubility of m(oh)2 in a 0.202 m solution of m(no3)2? ksp = 9.05×10−18?
saveliy_v [14]
<span>M(NO3)2 ==> [M2+] + 2 [NO3-] 0.202 M ==> 0.202 M M(OH)2 ==> [M2+] + 2[OH-] 5.05*10^-18 ===> s + [2s]^2 5.05*10^-18 ===> 0.202 + [2s]^2 5.05*10^-18 = 0.202 * 4s^2 4s^2 = 25*10^-18 s^2 = 6.25*10^-18 s = 2.5*10^-9 So, the solubility is 2.5*10^-9</span>
