N =14 a.m.u
H = 1 a.m.u
O =16 a.m.u
Therefore:
( NH₄)₂O = (14 * 2) + (1 * 4 *2) + (16* 1) => 52.0 g/mol
Answer:
The property of water which makes it to attach or stick to another surface is Adhesion.
Explanation:
Adhesion is the characteristic ability a substance possess to stick to other substances. This is as a result of the covalent bond existing between the two hydrogen atoms and the one oxygen atom in the water molecule.
An example of the property of Adhesion is a water drop that stuck to the end of the pine needles
Answer:
Manganese
Explanation:
Using rules you will find the location on 3d^5 because you subtract one level when in the d block
Extensive hydrogen bonding.
It takes a lot of energy to break hydrogen bonds and turn liquid water into a gas, therefore the boiling point for water is high.
Force /Area = Pressure
Force = Pressure * Area
