Answer:
Double Bonds
Explanation:
CO2 has two double bonds going from carbon to the oxygen atoms. Each oxygen atom needs to bond twice and the carbon atom needs to bond four times. Carbon has four valence electrons, and oxygen has six. Carbon shares two of its valence electrons with each of the two oxygen atoms, forming two double bonds.

Determine the heat required to raise the temperature of 9.4 mole of water from 75.0oC to 125oC at atmospheric pressure. Note that water transitions from the liquid to the vapor state. Express your answers in Joules.
The heat capacity required to raise the temperature of 9.4 mole of water from 75.0oC to 125oC at atmospheric pressure is 35429 J.
The following information is available from the question;
Number of moles = 9.4 mole
Initial temperature = 75.0oC
Final temperature = 125oC
Molar heat capacity = 75.38 J/mol °C
Now;
H = ncθ
m = Number of moles of water
c = Molar heat capacity of water
θ = Temperature rise
Substituting values;
H = 9.4 mole × 75.38 J/mol °C × ( 125oC - 75.0oC)
H = 35429 J

aspartame is the methyl ester of a dipeptide made of phenylalanine and aspartic acid. what are the expected products of the hydrolysis of aspartame?
Aspartame is an artificial sweetener that is 200 times sweeter than sucrose. The expected products from the hydrolysis of aspartame are;
MethanolAmino acids (Phenylanaline)AspartateAspartame is a methyl ester that is gotten from aspartic acid and phenylalanine dipeptide. Aspartame is used by many food companies as a replacement for sugar. It is deemed suitable for consumption.
The hydrolysis of aspartame takes place in the small intestine. There, it is immediately transformed to methanol, phenylalanine, and aspartate.
Further products that are obtained after hydrolysis are; formaldehyde and formic acid.

Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC Specific heat of water is: 4.184 J/gOC
The amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules
The amount of energy is expressed according to the formula expressed as:
[tex]E = mc\triangle \theta[/tex]
m is the mass of water = 7.40grams
c is the specific heat of water = 4.184 J/g⁰C
[tex]\triangle \theta = 46 - 29\\ \triangle \theta = 17^0[/tex]
Substitute the given parameters into the formula:
[tex]E = 7.4 \times 17 \times 4.184\\E=526.3472Joules[/tex]
Hence the amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules

What can you conclude about the symmetry of the C3H5 ion as it actually exists, as regards the bond lengths and the distribution of the positive charge
In the allyl cation, all the bond lengths are equal and the positive charge is delocalized over all the three carbon atoms.
The allyl cation has the formula C2H5+. In the allyl cation, the positive charge is delocalized over the three carbon atoms as shown in the image attached. Hence, relevant resonance structures can be proposed for the allyl cation.
The bond lengths in the allyl cation are intermediate between the bond lengths of double bonds and single bonds. All the bond lengths are equal.
