The % error in the second trial is calculated as follows
% error = actual molarity/ theoretical molarity x100
= 0.83/0.95 x100 = 87.4% error of second trial
Answer:
C.
Milk boils at about 212°F (100°C).
Explanation:
The boiling point is a physical property of every matter. Physical properties tell us what a substance is when no change is occuring to its constituents. Such properties can be observed with our senses or instruments or pieces of apparatus.
Some examples of physical properties are colour, taste, odour, hardness, texture, solubility in water.
They all depict what typifies a matter when no change whatever is imparted on them.
Hello!
The reactant CuSO₄ is an ionic compound.
Ionic compounds are formed by substances with a significative difference in their electronegativity. CuSO₄ is formed by two ions: Cu⁺² and SO₄⁻². These ions are attracted together by electrostatic forces and the compound formed is a crystalline solid, with a high melting point, fragile and easily dissolved in water.
Have a nice day!
Hi!
The answer would be <u>solid.</u>
<u>Explanation:</u>
There are three essential states of matter:
- Solid
- Liquid
- Gas
In a solid, the particles are seen to be in a strict orderly arrangement, and only show restricted movement about their place.
In a liquid, the particles do not have a particular arrangement, and have a more free movement with respect to solid, and can change their position through the sample.
In a gas, the particles are most widely spaced, and have no defined arrangement. They have the most free movement of the other two states.
