B reflecting light because the mirror interacts with the light reflection
Answer:
5 cm³.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of Rock =.?
The volume of the rock can be obtained as follow:
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 40 – 35
Volume of Rock = 5 mL.
Finally, we shall convert 5 mL to cm³.
This can be obtained as follow:
1 mL = 1 cm³
Therefore,
5 mL = 5 mL × 1 cm³ / 1 mL
5 mL = 5 cm³
Thus, we can say that the volume of the rock is 5 cm³.
A redox reaction occurs

Given
Reaction
Ca(ClO3)2 → CaCl2 + 3O2
Required
Type of reaction
Solution
The reaction equation is said to be a redox reaction if there is an oxidation reaction (increase in oxidation number) and a reduction reaction (decrease in oxidation number)
Oxidation number of Cl in Ca(ClO3)2 :+5
Oxidation number of Cl in CaCl2 = -1
Reduction : +5 to -1
O in Ca(ClO3)2 : -2
O in O2 : 0
Oxidation : -2 to 0
So there is a reduction and oxidation reaction
