<h2>Answer:</h2>
In the periodic table, the elements of the same group and elements of the same column, have similar reactivity because they have a similar configuration in their valence electrons.
There are some factors which determine the chemical properties if an element of the periodic table.
- No. of arrangement of electron in an atom.
- No. of valence electrons.
- Arrangement of electrons.
CTSO is an extracurricular program for students. The program helps the students build leadership qualities and career-specific skills.

Explanation: you subtract final temperature with initial temperature = 46 then multiply by grams = 552 then multiplied by J = 245.088
Answer:
Molarity = 0.08 M
Explanation:
Given data:
Mass of ZnCl₂ = 4.89 g
Volume of water = 500 mL (500 mL× 1L/1000 mL= 0.5 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
Number of mole ZnCl₂:
Number of moles = mass/molar mass
Number of moles = 4.89 g/ 136.3 g/mol
Number of moles = 0.04 mol
Molarity:
M = 0.04 mol / 0.5 L
M = 0.08 M
On the reactants side, you'll always have some sort of compound of carbon and hydrogen and oxide, while the products will always be CO2 (carbon dioxide) and H2O (water)
