Answer:
Al2(SO4)3
Explanation:
Looking at this carefully, we will discover that Al2(SO4)3 is composed of Al^3+ and SO4^2-.
The aluminum and sulphate ions are ionically bonded. However, the oxygen and sulphur in the sulphate ion are covalently bonded.
Hence, Al2(SO4)3 contains both ionic and covalent bond.
Answer:
Transition elements are elements which have partially filled d-orbitals and form at least one or more stable ions.
Answer: Bubbles, burning, odor, color change, and rusting.
Explanation: Chemical changes are changes to something that is irreversible.
The salt and water are a homogeneous mixture but when salt dissolves in the water system is called a solution of salt and water.
<h3>What is a mixture? </h3>
A mixture is defined as the combination of two or more substances that are not chemically bonded together.
There are two types of mixture which include:
- Homogeneous (uniform composition) and
When salt is added to the ice water system, it lowers the freezing point of the ice water thereby forming a homogenous mixture of water and salt.
The dissolution of salt in ice water leads to the formation of salt and water solution.
