Be sure to answer all parts. Write an unbalanced equation to represent each of the following reactions: Do not include phase abb

Eva8 [605]

Answer: 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.

For a:

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

$N_2+O_2\rightarrow NO_2$

The product formed is nitrogen dioxide.

For b:

The chemical equation for the decomposition of dinitrogen pentaoxide follows:

$N_2O_5\rightarrow N_2O_4+O_2$

The product formed is dinitrogen tetroxide and oxygen gas.

For c:

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

$O_3\rightarrow O_2$

The product formed is oxygen gas.

For d:

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

$Cl_2+NaI\rightarrow NaCl+I_2$

The product formed is sodium chloride and iodine gas

For e:

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

$Mg+O_2\rightarrow MgO$

The product formed is magnesium oxide

The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 1 x 10^6 microliters (mL) in 1 L.

35 kL (1,000 L/ 1kL) (1 x 10^6 microliters / 1 L) = 3.5 x 10^10 microliters

The volume of this pond in microliters is 3.5 x 10^10 microliters
