It releases algae into the ocean
Answer:
Explanation:
Precision relates to instruments of measurement or scale . A scale measuring upto cm is less precise than an instrument measuring upto mm .
Here the first measurement appears to have been taken with an instrument measuring up to metre and the second measurement appears to have been taken with an instrument measuring up to decimeter . So second measurement is most precise .
Third measurement is closest to the actual measurement that is 45.0 m , so it is most accurate measurement .
Answer:-
0.883 m
Explanation:-
Molality= Moles per Kg of solvent.
Molar mass of ethylene glycol= 62.07 g/ mol.
Number of moles of ethylene glycol= 82.2g / (62.07 g/mol)
= 1.324 moles
Density of water = 1 g/ml = (1/1000kg)/ (1/1000litre)
= 1 Kg / litre
Mass of 1.5 litre of water = 1.5 litre x 1 kg / litre
= 1.5 kg
Molality of ethylene glycol = 1.324 moles/1.5 kg
= 0.883 m
Answer is D breaking apart I to not more than two
I will state the electronegativities of each element.
Ca = 1.00
F = 3.98
H = 2.20
P = 2.19
Na = 0.93
The highest electronegative element is F (Fluorine).
