The dissociation of both salts NaCl and CaCl₂ are as follows;
NaCl --> Na⁺ + Cl⁻
CaCl₂ --> Ca²⁺ + 2Cl⁻
the molar ratio of NaCl to Cl⁻ is 1:1
therefore number of NaCl moles is equal to number of Cl⁻ ions dissociated from NaCl
then number of Cl⁻ ion moles - 0.233 mol/L x 0.1000 L = 0.0233 mol
molar ratio of CaCl₂ to Cl⁻ ions is 1:2
1 mol of CaCl₂ gives out 2 mol of Cl⁻ ions.
number of CaCl₂ moles - 0.150 mol/L x 0.2500 L = 0.0375 mol
then the number of Cl⁻ ion moles - 0.0375 x 2 = 0.0750
total number of Cl⁻ ion moles = 0.0233 mol + 0.0750 mol = 0.0983 mol
volume of solution - 100.0 + 250.0 = 350.0 mL
concentration of Cl⁻ = 0.0983 mol / 0.3500 L = 0.281 M
concentration of Cl⁻⁻ is 0.281 M
multiplying terrorist to power 23, divided by 96. Multiplied by 12.7. so this is 76.48
Answer:
It has a thick atmosphere which causes extremely high temperatures.
Explanation:
<span>Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed.
</span>
<span /><span /><span>
Explanation:
</span><span>1) Calcium hydroxide is a base whose chemical formula is: Ca(OH)₂</span>
<span /><span>
2) Hydrochloric acid is the acid with chemical formula HCl
</span><span>3) Acids and bases react in a double replacement reaction forming salt plus water: Acid + Base → salt + water
</span>
<span /><span /><span>
4) The specific chemical equation for these reactants is:
</span><span>Ca(OH)₂ (s) + 2HCl(aq) → CaCl₂ (aq) + 2H₂O(l)</span>
<span /><span>
</span><span>5) CaCl₂ is calcium chloride, a salt, and H₂O is water
</span><span>
</span>
<span>The charge of the ion becomes negative. This is because electrons naturally come with a negative charge. Adding one electron will make the charge 1-, as it was a balanced atom before taking on the additional particle.</span>
