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:
decreases
Explanation: decreases,as shelter is a limiting factor becasue the trees for example were there home now it is covered in melaleuca

Answer is in picture below.
Use 100 grams of the compound:
ω(Cl) = 85.5% ÷ 100%.
ω(Cl) = 0.855; mass percentage of the chlorine in the compound.
m(Cl) = 0.855 · 100 g.
m(Cl) = 85.5 g; mass of chlorine.
m(C) = 100 g - 85.5 g.
m(C) = 14.5 g; mass of carbon.
n(Cl) = m(Cl) ÷ M(Cl).
n(Cl) = 85.5 g ÷ 35.45 g/mol.
n(Cl) = 2.41 mol; amount of chlorine.
n(C) = 14.5 g ÷ 12 g/mol.
n(C) = 1.21 mol; amount of carbon.
n(Cl) : n(C) = 2.41 mol : 1.21 mol = 2 : 1.
This compound is dichlorocarbene CCl₂.
Answer:
The fox who shed their heavy coat in the summer.
Explanation:
If a fox has the ability to shed its coat in the summer, it will have no difficulties adapting to new temperatures even during winter. However, the heavy-coated one will.
