Answer:
double bond
Explanation:
Sometimes two covalent bonds are formed between two atoms by each atom sharing two electrons, for a total of four shared electrons. For example, in the formation of the oxygen molecule, each atom of oxygen forms two bonds to the other oxygen atom, producing the molecule O2. Similarly, in carbon dioxide (CO2), two double bonds are formed between the carbon and each of the two oxygen atoms

= 0.305
Answer:
C) 66 calories
Explanation:
The Heat energy required to flow into a unit mass object to raise its temperature by 1 degree is known as specific heat capacity.
specific heat capacity of aluminum, c = 0.22 cal/g°C
mass of aluminium, m = 20.0 g
