Over the next decade the Ogallala aquifer will be completely depleted and will affect portions of the central and southern High Plains Aquifer (HPA). The Ogallala Aquifer is one of the largest bodies of water in the United States and is is generally used by farmers for irrigation of crops. As the continuous depletion of the aquifer occurs, it may become problematic for agricultural industries to sustain their farming.
Answer:
The correct answer is - option b) 3Li .
Explanation:
Lithium that is occurring naturally have two isotopes that are stable one with an atomic mass of 7 and the other with an atomic mass of 6 both have the same atomic number.
In question 7(atomic mass) 3 (atomic number) is given and there is only two option have 3 atomic number with 3 b) 3.Li and d) 43Li. 4 atomic mass is not naturally occurring isotopes and as option b) has a no atomic mass so it would be the correct answer.
Thus, the correct answer is - option b) 3Li .

There are five signs that indicate a chemical reaction has occurred: odor, energy change, gas bubbles, precipitate formation, and color change. When any of these changes occur, the reaction is irreversible and cannot be undone.
Answer:
The corect answer is some of the reactants were spilled.
Explanation:
Before the initiation of the reaction the total mass of both reactants is 15.0 grams and after the reaction the net mass of product is grams 12.4grams.
This happens because during the reaction some reactant molecules were spilled which ultimately leads to decrease the mass of the reactant molecule.
The decrease in the amount of the reactant equals with amount of product formed.
