Answer:

On average, agriculture accounts for 70 percent of global freshwater withdrawals. In the last 30 years, food production has increased by more than 100 percent. FAO estimates that about 60 percent more food will be needed by 2050 to meet the food requirements of a growing global population.

the ph of a solution of HCl in water is found to be 2.50. what volume of water would you add to 1.00L of this solution to raise
morpeh [17]

<u>Answer:</u>

<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>

<u>Explanation:</u>

<em>Given that the pH of the solution of HCl in water is 2.5.</em>  Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. [H^+] ions contribute to a solution’s acidic nature and [OH^-]contribute to a solution’s basic nature.

The equation connecting the concentration of [H^+] and pH of a solution is pH= -log[H^+]

<em>[H^+]= 10^(^-^p^H^)[H^+]= 10^(^-^2^.^5^)=0.00316</em>

<em>When the pH is 3.1 [H^+ ]= 10^(^-^3^.^1^)=0.000794</em>

<em>On dilution the concentration of a solution decreases and volume increases.</em>

<em>M_1 V_1 = M_2 V_2</em>

<em>0.00316 \times 1 = 0.000794 \times V_2</em>

<em>V_2 = \frac{(0.00316 \times 1)}{0.000794} =3.24</em>

<em>Volume of water to be added =3.24-1</em>

<em>=2.24L</em>

Assume that matter does not consist of atoms. Show by example how this assumption leads to
Leviafan [203]

If matter was not composed of atoms, the law definite proportions and law of multiple proportions will not hold true because compound would have random composition.

<h3>What is the law of definite proportions and law of multiple proportions?</h3>

The law of definite proportions states that all pure samples of a compound contains the same element in a fixed mass ratio.

The law of multiple proportions states that if an element combines with another element to form more than one compound, the mass of the element combines with a fixed mass of the other element in whole number multiples ratios.

Assuming matter was not composed of atoms, the law definite proportions and law of multiple proportions will not hold true because, their will be no definite ratio or composition in compounds.

The law definite proportions and law of multiple proportions are required for the atomic theory as they help prove that matter consists of definite unique particles called atoms.

In conclusion, the existence of atoms is proved true by the law definite proportions and law of multiple proportions.
