Answer:
The classification and illustrations are attached in the drawing.
Explanation:
It is possible to identify the pure substance observing the figure, since it is the only one that has 2 joined atoms (purple and blue) which forms a single compound.
On the other hand, the homogeneous mixture is identified by noting that its atoms are more united with respect to the heterogeneous mixture, highlighting that in homogenous mixtures the atoms, elements or substances are not visible to the naked eye and are in a single phase, instead in the heterogeneous mixture if they can be differentiated.
<u>Answer:</u>
<u>For a:</u> The balanced equation is
<u>For c:</u> The balanced equation is
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
- <u>For (a):</u>
The given unbalanced equation follows:
To balance the equation, we must balance the atoms by adding 2 infront of both and
and 3 in front of
For the balanced chemical equation:
- <u>For (b):</u>
The given balanced equation follows:
The given equation is already balanced.
- <u>For (c):</u>
The given unbalanced equation follows:
To balance the equation, we must balance the atoms by adding 2 infront of
For the balanced chemical equation:
- <u>For (d):</u>
The given balanced equation follows:
The given equation is already balanced.
