Answer:
sodium ions and chloride ions
chloride ion
sodium ion
Explanation:
Ionic substances are composed of ions. When you dissolve an Ionic substance in water, the ions that compose the substance together with water molecules are present in solution.
Hence, when sodium chloride is dissolved in water, sodium ions and chloride ions are released in solution.
Water has a dipole moment. Hence, the chloride ions are attracted to hydrogen (the positive end of the dipole) while sodium ions are attracted to oxygen (the negative end of the dipole).
This is how the solid is dissolved in water.
Answer:
A
Explanation:
Conducts electricity:
-Steel
-Gold
-Copper
-Aluminum
Does not conduct electricity:
-Plastic
-Glass
-Rubber
-Wood
Metallic bonding causes metals to conduct electricity. Some metals are more highly conductive than others.
Hope this helps :)
Answer: Energy can be involved in disconnecting or connecting atoms to each other as the energy is used to break the bonds between the atoms ,so the reaction could proceed.
Explanation:<u> The statement can be well explained by the Planck's quantum theory , which states -:</u>
- In the form of small energy packets known as quanta of energy, energy is not released continuously, but discontinuously.
- The energy of each quantum is directly proportional to radiation frequency, i.e. E is directly proportional to v, where v is frequency E = hv, where h is the proportionality constant known as the constant of Planck.
- Any integer quanta will be the total energy of the radiation emitted or absorbed. Let the 'E' be the total radiation energy. So, when n is an integer, E'=nhv.
Hence, the given answer is based on the Planck's Quantum theory.
Answer:
Strong Electrolyte: Strong acids, strong bases and salts fall under this category. These compounds ionize completely.
Sulfuric acid H2SO4
Sodium hydroxide NaOH
Potassium chloride KCl
Weak Electrolyte: Weak acid and weak bases are weak electrolytes. These compounds do not ionize completely.
Carbonic acid H2CO3
Ethyl amine CH3CH2NH2
Non Electrolyte: This refers to compounds that are not capable of forming ions or dissociate into ions in a solution.
Sucrose C12H22O11
Methanol CH3OH
