The molar mass of nitrogen is 14.0067amu or just 14amu.
Answer:
<h3>Right answer is: ( a) chalk powder remains suspended in water.</h3>
Explanation:
Filtration is the technique used to separate suspended solute particles from a solution . The chalk powder remains suspended in the solution and can easily be filtered through a filter paper , the chalk powder can be collected on the filter paper and clear solvent is collected as the filtrate.
Answer: 165.6grams
Explanation:
Mass of a block = ?
Volume of block = 18 cm^3
Density of block = 9.2 g/cm^3
The density of any object depends on its mass and volume.
i.e Density of block = Mass / volume
9.2 g/cm^3 = Mass / 18 cm^3
Mass = 9.2 g/cm^3 x 18 cm^3
= 165.6 g
Thus, the mass of the block is 165.6grams
Answer:
Chemical symbols are used to standardize the 'language of chemistry' and to identify elements and atoms in a chemical formula easily. Chemical symbols consist of one or two letters, most often derived from the name of the element.
Explanation:
Yes, Bobby is correct
Explanation:
Anomalously high boiling point of water is as a result of the intermolecular forces between the molecules of water.
The intermolecular forces found in water are the very strong hydrogen bonds. The bulk of the physical properties of matter are due to the intermolecular forces that they possess.
- Hydrogen bonds are stronger than van der waals forces and they are more effective in binding molecules together into larger units.
- Substances whose molecules join via hydrogen bonds have higher boiling points i.e lower volatility than those with van der waals forces.
- Hydrogen bond is actually an electrostatic attraction between hydrogen atom of none molecule and the electronegative atom(O or N or F) of a neighboring molecule.
