The first reaction from the scale Cl2 + BaF2 is <span>decomposition, remember! that H20 should be broken down.
The third one is </span><span> metal ion substitution
The last one is decomposition again.
</span><span>The second one is </span>H2 + Cl2 has been combined in order to synthesize <span> 2HCl, so that's the answer.</span>
Answer:
- <em>The molarity of the solution is </em><u>1.0 M</u>
Explanation:
<u>1) Data:</u>
a) n = 0.50 mol
b) V = 500 ml
c) M = ?
<u>2) Formula:</u>
- Molarity, M = number of moles of solute / volume of solution in liters
M = n / V (liter)
<u>3) Conversion of units:</u>
- 500 ml × 1.00 liter / 1,000 ml = 0.500 liter
<u>4) Solution:</u>
Substitute in the formula:
- M = n / V (liter) = 0.50 mol / 0.500 liter = 1.0 mol / liter = 1.0 M
The answer must be reported with two significant figures.
Zinc will always have 30 protons, so you'd have 66-30 = 36 neutrons
I hope it helped you!
