Answer: single covalent bond
Explanation: Chlorine is a simple molecule. each chlorine atom can count 8 electrons in its outer shell. with other chlorine atoms. One pair of shared electrons form a single covalent bond.

Your answer would be the solute in the ocean water. Hope this helps!
A) It would increase.
Explanation:
The gravitational force between the two masses will increase.
This is in compliance with universal law of gravitation proposed by newton.
Newton's law of universal gravitation states that "the gravitational force of attraction between two masses is directly proportional to the product of the masses and inversely proportional to the square of the distance them".
From law, we can establish that the gravitational force is directly proportional to the product of the masses between two bodies.
The higher the mass, the higher the gravitational force.

9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).
<h3>What is Significant figures ?</h3>
The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.
The given chemical equation ;
4NH₃ + 5O₂ ---> 4NO + 6H₂O
Therefore,
4 moles of NH₃ reacts with 5 moles of O₂.
i.e,
68 g of NH₃ reacts with 160g of O₂.
Therefore,
9.98 g of NH₃ reacts with :
= 160/68 x 9.98
= 23.4 g of O₂ (up to 3 significant figure)
