Density:
The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.
Density = mass in g / volume in cubic cm or ml
Given that
Density = 8.92 g/ ml
Mass = 40.0 g
Therefore,
Volume = mass/ density
= 40.0 g/ 8.92 g/ ml
= 4.48 ml
Thus the correct answer is 4.48 ml
So the whole point is that you need a abstract.
Answer:
a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Explanation:
A hydrogen bond is a partial intermolecular bonding interaction between a lone pair on an electron rich donor atom, particularly the second-row elements nitrogen, oxygen, or fluorine, and the antibonding molecular orbital of a bond between hydrogen and a more electronegative atom or group.
The description that you are probably looking for is a Monohybrid Cross.
Answer:
false
Explanation:
it can be differ when the concentration,surface area and when the rate of reaction is changed
