Graphite and diamond are allotropes of carbon. Allotrophy is the existence of an element in more than one form but the same physical state. Carbon is an example of element that exhibits allotrophy; these are diamond and graphite; which differ in structure and chemical properties. Another element that exhibits allotrophy is sulfur; with monoclinic and rhombic sulfur.
Answer:4
Explanation:To balance the equation you need to make the number of each element equivalent in both sides.
To start add a 2 in front of the MnO2 which balances the Mn.
Then balance the oxygen by adding a 4 in front of H20.
The H then needs a 8 as it’s coefficient.

Answer:
14.68 oz
Explanation:
The mean volume is the average volume of all the regular soda cans put together; 14.5 oz. The standard deviation 0.18 oz is the maximum deviation from the mean. It can be 14.5-0.18= 14.32 oz which is the usual minimum or 14.5 + 0.18=14.68 oz which is the usual maximum
