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.
26.82m/s
Explanation:
Given:
speed = 60mph
problem: convert to m/s
To solve this problem, we have to find the right and appropriate conversion factor which equals to 1 to multiply this unit with:
we are converting:
miles to meters
hours to seconds
1.609km = 1mile
1000m = 1km
60s = 1 min
60 min = 1hr
Now to convert from mph to m/s
60 x x
= 26.82m/s
