Balancing Chemical Equations Write and balance the equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.

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.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
