Answer:
Distillation
Explanation:
The method of distillation can be used to separate the two liquids, if their boiling point is known. The liquid with lower boiling point will be evaporated and its vapours will be captured, while the liquid with higher boiling point will remail in the container in the liquid state.
A is the answer
In an ozone molecule, the three atoms must be connected, so there must at least be a single bond between them. Place
dots in pairs around the oxygen atoms until each oxygen atom has eight valence electrons, starting with the atoms on the
outside and doing the central atom last if there are enough. Do not exceed the total number of valence electrons
identified in part A. Remember that the dashes between the oxygen atoms, which represent single bonds, each indicate
the presence of two valence electrons
Answer:
<h3>25.0 grams is the mass of the steel bar.</h3>
Explanation:
Heat gained by steel bar will be equal to heat lost by the water
Mass of steel= 
Specific heat capacity of steel = 
Initial temperature of the steel = 
Final temperature of the steel = 
Mass of water= 
Specific heat capacity of water=
Initial temperature of the water = 
Final temperature of water =
On substituting all values:
<h3>25.0 grams is the mass of the steel bar.</h3>
