Answer:
Option (B) is correct.
The mass of the reactants equals the mass of the products.
Step-by-step explanation:
According to law of conservation of mass :
In a balanced chemical equation, the mass of reactants is always equal to the mass of products.
Here, Water 
is the reactant which has 4 units of Hydrogen and 2 units of oxygen.
and 
are products which also has 4 units 4 units of Hydrogen and 2 units of oxygen.
Thus, The mass of the reactants equals the mass of the products.
Thus, option (B) is correct.
The probability that he lost less than 19 pounds is 7 / 9.
According to statement
The weight loss by individual is 12 Pounds
So, by uniform distribution probability
P(c ≤ x ≤ d) = (d - c) / (b - a)
Substitute the values in it then
P(12 ≤ x ≤ 19) = (19 - 12) / (20 - 11)
P(12 ≤ x ≤ 19) = 7 / 9
So, the probability that he lost less than 19 pounds is 7 / 9.

QUESTION B:</h3>
Graph C.
This graph tricks the human brain into thinking that the increase is less prominent than we might perceive it in Graph A or B. This is because it is located lower and has a shallower slope. The campaign that wants to prevent immediate radical action (action which would harm the native species) would want to use this one as it might convince the city counsel that the issue is not urgent enough to take such actions so quickly.
