SInce earths gravitational force is 9.81, and outer space is less than that, the force decreases
Answer:
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

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)
