Answer:
A is the answer
Explanation:
Because water freezes when it gets to a certain temperature
Answer:
Substances which are non heat-resistant and volatile organic liquid with flammable vapor.
Explanation:
Bunsen Burner are used as a source of fire in the laboratory for heating up substances. Extra care however should be taken during heating in order to prevent fire or other forms of accidents.
Heating of mind heat resistant substances should be frowned at as the substances may get heated up and melt thereby exposing the liquid substances which may be flammable to fire thereby causing fire outbreak.
Heating of volatile organic liquid with flammable vapor should also be discouraged to prevent fire accidents.
Answer: AIBN is good radical initiator
Explanation:
A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.
A solid dissolves in a liquid when it mixes completely with the liquid. ... Things which dissolve are called solutes and the liquid in which they dissolve is called a solvent to form a solution
Answer:
1 g/mL.
Explanation:
From the question given above, the following data were obtained:
Volume = 100 mL
Mass = 100 g
Density =?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. The density can be expressed mathematically as:
Density (D) = mass (m) / volume (V)
D = m / V
With the above formula, we can obtain the density of the liquid as follow:
Volume (V) = 100 mL
Mass (m) = 100 g
Density (D) =?
D = m / V
D = 100 / 100
D = 1 g/mL
Thus, the density of the liquid is 1 g/mL
