Answer:
Molarity = 0.24 M
Explanation:
Given data:
Number of moles of Mg(NO₃)₂ = 0.181 mol
Volume of solution = 0.750 L
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
by putting values,
Molarity = 0.181 mol / 0.750 L
Molarity = 0.24 M

A.Electrolysis
For example, electrolysis of solution of NaCl in water gives H2 and O2.
Answer:
Silicon
Explanation:
One of the most similar elements to carbon on periodic table is silicon. Several compounds formed between carbon or silicon and other elements are identical.
Carbon is an element found in life forms as a building block while silicon is a building block of machine components such as semiconductors
Silicon is an element that can sustain bonds, similar to carbon bonds and it is situated directly under carbon on the periodic table
