Answer:

3

Explanation:

The unbalanced combustion reaction of the oxidation of propane is shown below as:-

C_3H_8+O_2\rightarrow CO_2+H_2O

On the left hand side,

There are 3 carbon atoms and 8 hydrogen atoms and 2 oxygen atoms

On the right hand side,

There are 1 carbon atom and 2 hydrogen atoms and 3 oxygen atoms

Thus,

Right side, CO_2 must be multiplied by 3 and H_2O by 4 so to balance carbon and hydrogen.

Left side, O_2 is multiplied by 5 so to balance the whole reaction.

Thus, the balanced reaction is:-

C_3H_8+5O_2\rightarrow 3CO_2+4H_2O

<u>Coefficient in front of the carbon dioxide in the balanced equation - 3</u>

The modern periodic table is arranged in order of increasing. true or false
qaws [65]

Answer:

Increasing atomic number - True

Explanation:

The modern table is based on Mendeleev’s table, except the modern table arranges the elements by increasing atomic number instead of atomic mass.

The Atomic number is the number of protons in an atom, and this number is unique for each element. For example, Hydrogen has an atomic number of 1, Calcium has an atomic number of 20.

In the modern periodic table the elements are further arranged into:

- rows, called periods, in order of increasing atomic number. Elements in the same periods have the same number of shells.

- vertical columns, called groups, where the elements have similar properties. Elements in the same group has the same number of valency (outermost number of electrons)
