Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
Explanation:
Answer:
Calcium can be ignited and will when burning react with both oxygen and nitrogen forming calcium oxide, CaO, and calcium nitride, Ca3N2.
Hi! For the first question: this isn’t true. It can’t be done. Animals can’t evolve from other animals.
1) convert Celsius to Kelvin
24 + 273 = 297
2) convert kPa to atm
62.2 / 101.3 = 0.614
3) plug numbers into the ideal gas law formula
Answer: 0.088 mols
Organic compounds that contain only hydrogens and carbons are known as hydrocarbons. Hydrocarbons can be saturated or unsaturated in nature. Saturated hydrocarbons are those which contain only carbon-carbon single bonds whereas unsaturated hydrocarbons contain carbon-carbon double or triple bonds. Hydrocarbons can undergo several reactions like substitution, elimination etc.
When one or more hydrogen atoms in hydrocarbon are substituted with halogen it results in the formation of haloalkane. Due to which the molecular weight increases as the halogen atoms are large compared to the carbon and hydrogen atoms. The bond becomes polar due to the presence of electronegative halogen atom and thus results in the increase in boiling point of the haloalkane.
Thus, the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
