\begin{aligned}&\mathrm{N}_2(g)+\mathrm{O}_2(g) \longrightarrow 2 \mathrm{NO}(g) \\&2 \mathrm{NO}(g)+\mathrm{O}_2(g) \longrightarrow 2 \mathrm{NO}_2(g) \\&3 \mathrm{NO}_2(g)+\mathrm{H}_2 \mathrm{O}(g) \longrightarrow 2 \mathrm{HNO}_3(a q)+\mathrm{NO}(g)\end{aligned}

The above is balanced equations for the reactions mentioned in the question.

<h3>What is balanced equation?</h3>

A balanced reaction equation demonstrates atom conservation by displaying not only the several forms the reactants might take but also their amounts and quantities.

For instance, H + O H0 is the equation for the reaction between hydrogen and oxygen in its most basic form.

However, water is H₂O (the reaction proportion is 2:1, not 1:1), hence the equation needs an adjust: H₂ + O → H₂O.

However, due to the fact that oxygen occurs as diatomic molecules (O2), that is not yet the correct, final form. So put that: H2 + O2 H2O.

The amount of atoms on the left and right sides do not match, so this is not good enough. It is also not yet in balance. The coefficients must be changed in order for the right numbers to appear everywhere:

2H₂ + O₂ → 2H₂O

It works like this: on the left, there are 4 H atoms and 2 O atoms, and on the right, there are 4 H atoms and 2 O atoms.

An object with a mass of 3.5 g raises the level of water in a graduated cylinder from 25.1 mL to 31.7 mL. What is the density of
vodomira [7]

density of the object = 0.53 g/mL

Explanation:

First we need to find the volume of the object which is equal to the rise of the water in the graduated cylinder:

volume = 31.7 - 25.1 = 6.6 mL

Now we calculate the density of the object using the following formula:

density = mass / volume

density = 3.5 g / 6.6 mL

density = 0.53 g/mL
