Answer:
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
Explanation:
Let's consider the unbalanced equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.
NCl₃ + H₂O = HNO₂ + HCl
We start balancing Cl atoms by multiplying HCl by 3.
NCl₃ + H₂O = HNO₂ + 3 HCl
Then, we balance O atoms by multiplying H₂O by 2.
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
The equation is now balanced.
The answer is For this question is B
Answer:
Homeostasis is the quality of a living being to control its inside conditions. A model is the body directing its inside temperature by shuddering or perspiring. The body controls the measures of acids and bases in the blood.

2.1 x 10²²atoms
Explanation:
Given parameters:
Mass of silver = 3.78g
Unknown:
Number of atoms of silver = ?
Solution:
To solve this problem, we first find the number of moles of the silver from the given mass.
Number of moles =
Molar mass of Ag = 108g/mole
Number of moles = = 0.035mole
Now;
A mole of any substance contains 6.02 x 10²³ atoms
0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms
