The complete question is: A student draws a picture of the products and reactants of a chemical reaction. What, if anything, is wrong with the drawing?
A) The drawing is wrong because there are more chemicals on the products side.
B) The drawing is correct because there are 12 compounds on each side of the arrow.
C) The drawing is wrong because there are different compounds on each side of the arrow.
D) The drawing is correct because there are 12 atoms of each type on each side of the arrow.
Answer:
Option D is correct
Explanation:
In the diagram attached below, it can be seen that there are 12 atoms of element which combine with 12 atoms of another element forming a compound. For the drawing to be correct, there should be 12 atoms of each type of element on both the reactants as well as product side, which is the case. There cannot be imbalance in the number of atoms of different elements on the two sides for a chemical reaction to occur.
Hence, option D is correct.

Answer:
6.4 × 10^7 W/m^2
Explanation:
The sun is assumed a sphere and therefore can be calculated by the surface area of a sphere.
surface area of sphere = 4πr^2 where r is the radius of the earth in m.
r = 6.96 ×10^8 m
substitute the value into the formula
surface area of the sun = 4 × 3.142 × ( 6.96 × 10^8)^2
the sun radiates at a rate of 3.90 × 10^26 W
to calculate the rate of energy emitted per square meter of the sun, we need to divide the rates at which the sun radiates energy per second by the surface area of the sun
that is P/surface area = 3.90 × 10^26 / ( 4 × 3.142 × ( 6.96 × 10^8)^2 = 6.4 × 10^7 W/m^2
