The answer is 0.50 mol. The number of moles of potassium bromide in the beaker will not change since there is no additional potassium bromide introduced to the solution. The molarity of potassium bromide, the number of moles of water, the volume of the water solvent and the volume of the solution will all change if water is added.
The number of H atoms in 3(NH₄)₂CrO₄ = 24
<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
Subscripts in the chemical formula indicate the number of atoms
The compound of 3(NH₄)₂CrO₄ ( 3 molecules of (NH₄)₂CrO₄ ) :
Number of H :

Answer:
Hydrogen bonding
Explanation:
Water is a compound found readily in nature. It is made up of interatomic forces of covalent bonds that connects the hydrogen and oxygen bonds together in a definite ratio.
- The intermolecular forces are responsible for the physical properties of substances.
- These forces allows a compound to behave in certain ways.
- In water, the intermolecular bonding present are the very strong hydrogen bonds.
- For this bond type, the hydrogen of one water molecule is firmly attached to the oxygen of another water molecule.
- The bonds are very strong forces.
Answer:
bromine water
Explanation:
a simple test with bromine water can be used to tell the difference between an alkane and an alkene. an alkene will turn brown bromine water colourless as the bromine reacts with the carbon-carbon double bond.
