Balanced equation:
Ca(OH)2+H2SO4=CaSO4+2 H20<span />
Answer:
1.47 mol/L
Explanation:
Molarity is given as,
Molarity = Moles / Vol in L ------- (1)
Moles of CaCl₂,
Moles = Mass / M.Mass
Moles = 535 g / 110.98 g/mol
Moles = 4.82 mol
Now, putting values in eq. 1.
Molarity = 4.82 mol / 3.28 L
Molarity = 1.47 mol/L
ANSWER Since 1.0 × 10 -7 has two significant figures, the pH can be reported as 7.00. A logarithmic scale condenses the range of acidity to numbers that are easy to use. Consider a solution with [H + ] = 1.0 × 10 -4 M. That is a hydrogen-ion concentration that is 1000 times higher than the concentration in pure water.

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.
The balanced chemical reaction is :
<em> 2Na + Cl₂ → 2NaCl</em>
<em />
Given data :
Mass of sodium = 10.0 g
Number of moles of Na -
Number of moles = <u> Given mass </u>
Molar mass
Number of moles = <u> 10.0 g</u> = 0.43 mol
23 g
Comparing moles of Na and Cl₂ from the balanced chemical equation,
Na : Cl₂
2 : 1
0.43 : <u> 1 </u> x 0.43 = 0.215 mol
2
Mass of chlorine gas :
(molar mass of chlorine = 71 g)
Mass of chlorine = number of moles x molar mass
Mass = 0.215 mol x 71 g/mol
= 15.26 g
