Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.
<h3>What is a double bond?</h3>
A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.
A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.
Therefore, hydrogen molecules cannot form a double bond.

Answer:The correct answer option A.
Explanation:
Q= heat removed from the water
m= mass of the water = 80 grams
c = heat capacity of water= 4.18 J/g°C
Q = -10,032 joules 
-10,000 Joules
Negative sign indicates that heat was removed from the water.
Heat removed from the water of 80 gram of water is 10,032 Joules.Hence, the correct answer option A.
