Answer:
The molarity of the diluted HCl solution: <u>M₂ = 0.045 M</u>
Explanation:
To find- the molarity of the diluted HCl solution (M₂)
Given- <u>For original HCl solution</u>-
Molarity: M₁ = 1.5 M, Volume: V₁ = 60.0 ml = 0.06 L (∵ 1L = 1000 mL)
Then this original solution is diluted to a volume of 2 L
Thus <u>for the diluted HCl solution</u>-
The Volume of the diluted HCl solution: V₂ = 2 L
<u>So the Molarity of the diluted HCl solution (M₂) can be calculated by the </u><u><em>dilution equation:</em></u>
<u>Therefore, the molarity of the diluted HCl solution: M₂ = 0.045 M</u>
Answer:
ΔEN CO = 1.0
Explanation:
To calculate the electronegativity difference, we have to substract the element which has the highest EN to the other, that has a low value.
For this case EN from O - EN from C
Electronegativity is a property of the periodic table that increases diagonally, where Fr and Rb are the elements of less EN while F is the most electronegative element, with a value of 4. This is because F is an element with a high ionization energy and a negative electronic affinity.
ΔEN CO = 3.5 - 2.5 = 1.0
Electronegativity (EN) describes the ability of an atom to compete for
electrons with other atoms to which it is attached.

Answer:80%
Explanation:Total C in terrestrial ecosystems is approximately 3170 gigatons (GT; 1 GT = 1 petagram = 1 billion metric tons). Of this amount, nearly 80% (2500 GT) is found in soil (Lal 2008).
