Answer:
6 x 10⁵ kg Hg
Explanation:
The mass of mercury in the entire lake is found by multiplying the concentration of the mercury by the volume of the lake.
The volume of the lake is calculated in cubic feet:
V = (SA)x(depth) = (100mi²)(5280ft/mi)² x (20ft) = 5.57568 x 10¹⁰ ft³
Cubic feet are then converted to mL (1cm³=1mL)
(5.57568 x 10¹⁰ ft³) x (12in/ft)³ x (2.54cm/in)³ = 1.578856752 x 10¹⁵ mL
The mass of mercury is then found:
m = CV = (0.4μg/mL)(1g/10⁶μg)(1kg/1000g) x (1.578856752 x 10¹⁵ mL) = 6 x 10⁵ kg Hg
Its the other way around actually. Benzoic acid is stronger than acetic acid because the electron-donating inductive effect (+I) by the alkyl group on acetic acid destabilise the conjugate base of acetic acid.
hope this helps :)
The answer would be 1.86 x 10^4
Answer: Gas , Solid and Liquid
Explanation:
To complete each sentence , One can easily conclude that the various state of matter are in question here.
To further explain better,
(1) Gas molecule is consider to b moving and also move at a faster rate is respect to others.
(2)Solid molecule usual takes a standing still position unless an external pressure acts on it.
(3) Liquid molecule is capable of starting at same location and then move to another location but not at a faster rate compare to gas molecule.
