Answer:
pH = 2.0
Explanation:
To find the pH of a solution, take the -log[H+]. In this case, the -log(9.4 x 10^-3) equals 2.02687 which makes 2.0 when accounting for significant figures.
When Al(OH)3 and H2SO4 are allowed to react, the products formed are aluminum sulfate (Al2(SO4)3<span> ) and water (H2O). The balanced equation should be written as follows:
</span><span>3H2SO4 + 2Al(OH)3 = Al2(SO4)3 + 6H2O
This reaction is called a neutralization reaction. Hope this answers the question. Have a nice day.</span>
Answer:
0.006 mol of CaCl2 are present
Explanation:
Use dimensional analysis for this:
60.0 mL CaCl2/1 * 1 L/1000 mL * 0.10 mol/1 L = 0.006 mol
If you were to write this as fractions out on paper, you'll see that all of the units will cancel out and you'll be left with moles of CaCl2.
**REMEMBER** that molarity (M) is talking about how many moles of that substance is present in one Liter of solvent.
Hope this helps :)
<span>1 gallon = 4. 5 litres
1 litre = 1/4.5 gallons = 2/9 gallons
1 km = 5/8 mile
9.8 km = 9.8 x 5/8 miles = 49/8 miles
49/8
-------- mpg
2/9
49 x 9
--------- mpg
16
27.6 mpg </span>
