<h3><u>Answer;</u></h3>

R'

C = O

. |

R

<h3><u>Explanation; </u></h3>
  • Ketones are byproducts of the breakdown of fatty acids.<u> They are organic compounds with the structure R(C=O)R', where R and R' can be a variety of carbon-containing substituents.</u>
  • Like aldehydes ketones contain a carbonyl group that is a carbon oxygen double bond.

What is the specific heat of a substance that absorbs 2500 joules of heat when a sample of 100g of the substance increases in te
Ierofanga [76]

Answer:

0.417 J/gºC

Explanation:

From the question given above, the following data were obtained:

Heat (Q) absorbed = 2500 J

Mass (M) of substance = 100 g

Initial temperature (T1) = 10 °C

Final temperature (T2) = 70 °C

Specific heat capacity (C) =?

Next, we shall determine the change in temperature (ΔT). This can be obtained as follow:

Initial temperature (T1) = 10 °C

Final temperature (T2) = 70 °C

Change in temperature (ΔT) =?

Change in temperature (ΔT) = T2 – T1

Change in temperature (ΔT) = 70 – 10

Change in temperature (ΔT) = 60 °C

Finally, we shall determine the specific heat capacity of the substance as follow:

Heat (Q) absorbed = 2500 J

Mass (M) of substance = 100 g

Change in temperature (ΔT) = 60 °C

Specific heat capacity (C) =?

Q = MCΔT

2500 = 100 × C × 60

2500 = 6000 × C

Divide both side by 6000

C = 2500 / 6000

C = 0.417 J/gºC

Therefore, the specific heat capacity of substance is 0.417 J/gºC

The substances sodium (Na), oxygen (O2), and sodium oxide (Na2O) participate in this chemical reaction:
Andrews [41]

The chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.

<h3>What are chemical reactions?</h3>

Chemical reactions are changes which occur in the chemical composition of atoms of substances which results in the formation of new substances.

There are different types of chemical reactions such as:

  • synthesis reaction
  • displacement reaction
  • double displacement reactions

A synthesis reaction is a reaction in which two or more substances combine to form a new product.

Therefore, the chemical reaction involving sodium and oxygen as given in the reaction: 4Na + O2 → 2Na2O is a synthesis reaction.
