<span>Since weight is a force, it is measured in Newtons. Note: Many people confuse weight with mass; the unit for mass is the kilogram.</span>
Luster is the term- means the shininess of the metal
Answer:
21%
Explanation:
We have a mass of 210.0 g of NaCl and a volume of 1000 mL. To find the percentage solution (m/V), we would divide % percentage solution.
iii. True. The existence of a vacancy in a crystal decreases the energy of the material.
One of the scientific disciplines called crystallography examines how the atoms in a solid crystal are arranged. When molecules are linked together in a regular way, these crystals are created.
The mechanical, physical, and optical properties of a material can alter when crystal flaws are present. The strength of the material can be impacted by a flaw.
An irregularity in the atoms' regular geometrical arrangement within a crystalline material is referred to as a crystal defect. These flaws are caused by the solid being deformed, cooling quickly from a high temperature, or being exposed to high-energy radiation (such as X-rays or neutrons). because the vacancy cause defects and the crystal structure is disturbed this causes a decrease in energy.
