Is cubr2 an ionic or covalent compound?

Answer : The compound is an ionic compound.

Explanation :

Ionic compound are the compounds where the atoms are bonded through ionic bond.

Ionic bonds are formed by the complete transfer of electrons. The atom which looses the electron is considered as electropositive atom and the atom which gains the electron is considered as electronegative atom.

The ionic bonds are formed between one metal and one non-metal.

Covalent compound are the compounds in which atoms are covalently bonded.  

Covalent bonds are formed by the equal sharing of electrons. These bonds are commonly formed between two non-metals.

In the given compound , copper (Cu) is a metal and bromine (Br) is a non-metal. So, will form ionic bond.

Hence, the compound is an ionic compound.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
