Soudium chloride is classifeid as salt.
Answer:
cesium
Explanation:
The most reactive metal on the periodic table is francium. However, francium is a man-made element and only minute quantities have been produced, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more vigorously.
Answer:
Molarity = 1 mol.L⁻¹
Solution:
Molar concentration (Molarity) is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Moles = 4 mol
Volume = 4 L
Putting Data in Eq. 1,
Molarity = 4 mol ÷ 4 L
Molarity = 1 mol.L⁻¹
