Be sure to answer all parts. write an unbalanced equation to represent each of the following reactions: do not include phase abbreviations. (a) nitrogen and oxygen react to form nitrogen dioxide. (b) dinitrogen pentoxide reacts to form dinitrogen tetroxide and oxygen. (c) ozone reacts to form oxygen. (d) chlorine and sodium iodide react to form iodine and sodium chloride. (e) magnesium and oxygen react to form magnesium oxide.

The unbalanced chemical equations are written below.

Explanation:

An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.

The chemical equation for the reaction of nitrogen gas and oxygen gas follows:

The product formed is nitrogen dioxide.

The chemical equation for the decomposition of dinitrogen pentaoxide follows:

The product formed is dinitrogen tetroxide and oxygen gas.

The chemical equation for the reaction of ozone to oxygen gas follows:

The product formed is oxygen gas.

The chemical equation for the reaction of chlorine and sodium iodide follows:

The product formed is sodium chloride and iodine gas

The chemical equation for the reaction of magnesium and oxygen gas follows:

The product formed is magnesium oxide

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
