Answer:

last step= [Pb(H2O)4]^2+ (aq) -----> [PbCl(H20)3]^+ (aq) + H2O (l)

Explanation:

Please see attachment for part of the equation.

The balanced chemical equation for the last step is;

last step= [Pb(H2O)4]^2+ (aq) -----> [PbCl(H20)3]^+ (aq) + H2O (l)

Describe the reactions during the electrolysis of waterA) Oxygen is reduced and hydrogen is oxidized.B) Oxygen and hydrogen are
Natalka [10]

Answer:

D) Oxygen is oxidized and hydrogen is reduced.

Explanation:

In the electrolysis of water, an electric current passes through an electrolytic solution (e.g. aqueous NaCl), leading to the following redox reaction.

H₂O(l) → H₂(g) + 1/2 O₂(g)

The corresponding half-reactions are:

Reduction:  2 H₂O(l) + 2 e⁻ → H₂(g) + 2 OH⁻

Oxidation:  2 H₂O(l) → O₂(g) + 4 H⁺(aq) + 4 e⁻

As we can see, H in water is reduced (its oxidation number decreases from 1 to 0), while O in water is oxidized (its oxidation number increases from -2 to 0).

How are organelles connected to cell theory?
dsp73

Answer: bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Explanation: An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Liquid hexane, C6H14, burns in oxygen gas to yield carbon dioxide and water. What is the minimum mass of oxygen required for the
Usimov [2.4K]

Answer: 46.6 grams

Explanation:

2C_6H_{14}+19O_2\rightarrow 12CO_2+14H_2O

Given : density of hexane = 0.660 g/ml

volume of hexane = 20 ml

Mass of hexane = {\text {density of hexane}}\times {\text {volume of hexane}}=0.660g/ml\times 20ml=13.2g

moles of hexane =\frac{\text {given mass}}\times {\text {molar mass}}=\frac{13.2g}{86.18g/mol}=0.15moles

According to stoichiometry :

2 moles of hexane reacts with 19 moles of oxygen

Thus 0.14 moles hexane will react with =\frac{19}{2}\times 0.15=1.45 moles of oxygen

Mass of oxygen =moles\times {\text {molar mass}}=1.45\times 32=46.6g

Thus minimum mass of oxygen required for the complete reaction of 20.0 mL of hexane is 46.6 grams.
