Answer:
Chlorine is a chemical element with the symbol Cl and atomic number 17.
Answer:
The number of protons each element has.
Explanation:
The periodic table is arranged by atomic number, which is the number of protons in the nucleus of each element.
Answer:
0.366m = Molality of the solution
Explanation:
To solve this question we must know the addition of a solute produce decreasing in freezing point regard to the pure solvent. The equation is:
ΔT = m*Kf*i
<em>Where ΔT is change in freezing point </em>
(As freezing point of water is 0°C, the ΔT is 2.72°C)
<em>Kf is freezing point depression constant = 1.86°C/m for water</em>
<em>i is Van't Hoff factor. The number of ions produced when 1 mole of the salt is dissolved = 4 ions for Fe(ClO₃)₃, Fe³⁺ and 3 ClO₃⁻ ions</em>
<em>m is molality of the solution.</em>
<em />
Replacing:
2.72°C = m*1.86°C/m*4
<h3>0.366m = Molality of the solution</h3>

Answer:
2H2O2-----2H2O+O2
Explanation:
This is because theres the same number of atoms of each element on both sides
