Answer:
Y is a gamma ray in a nuclear equation, which y equals 0.
They should throw it away and use a different one
This type of a reaction is a double displacement reaction. where the reactants displace each other. the cations and the anions the reactant compounds replace each other or in other words switch places. the anion of one compound will bond with the cation of the other compound and vice versa.
the equation for the above is
Na₂S + CdSO₄ ---> CdS + Na₂SO₄
the numbers of atoms on both sides are balanced now
Answer:
yes it is as it has a chemical formula which cannot be changed
Answer:
The correct option is: D. Two types of secondary (or intermolecular) bonding are present between hydrogen fluoride molecules, whereas only one type of secondary bonding is present between hydrogen chloride molecules
Explanation:
Boiling point of a chemical substance depends on the molecular mass and the intermolecular forces, which are the interactive forces present between chemical species
1. The <u>molecular mass of hydrogen fluoride (HF) is less than hydrogen chloride (HCl). </u>
2. But the <u>intermolecular forces present between the HF molecules are stronger </u>than the intermolecular forces present between the HCl molecules.
This is because hydrogen fluoride exhibits two types of intermolecular forces: strong hydrogen bonding and dipole-dipole interactions. Whereas, hydrogen chloride exhibits only one type of intermolecular force i.e. dipole-dipole interactions.
<u>Therefore, as a net result, the boiling point of HF is higher than the boiling point of HCl.</u>
