Question

In experiment 2 we plan to use 100 ml of 1.00 M HCl and approximately 2 g of NaOH. What is the limiting reagent and how many grams of water will be produced? How many moles of the excess reagent will be left? Show your work briefly for full credit.

Answer #1

In the experiment, you performed the reaction below. (You added
5 ml of 0.40 M NaOH in methanol to 20 mL of cooking oil.)
The density of cooking oil is 0.895 g/mL and its molar mass is
885.43 g/mol. The formula for glycerol is C3H8O3. The density of
cooking oil is 0.895 g/mL and its molar mass is 885.43 g/mol.
How many moles of cooking oil are in 20 mL of cooking oil?
Starting with 20 mL of cooking oil,...

1.00 mL of 12.0 M HCl is added to 1.00 L of a buffer that is
0.130 M HNO2 and 0.200 M NaNO2. How many moles of
HNO2 and NaNO2 remain in solution after addition of the HCl?
moles HNO2 =
moles NaNO2 =

1.00 mL of 12.0 M HCl is added to 1.00 L of a buffer that is
0.120 M HNO2 and 0.180 M NaNO2. How many moles of HNO2 and NaNO2
remain in solution after addition of the HCl?

Suppose a student adds 25.00 mL of 1.041 M HCl to a 1.50 g
antacid tablet. The student boils and then titrates the resulting
solution to the endpoint with 0.4989 M NaOH. The titration requires
21.1 mL NaOH to reach the endpoint. How many moles of HCl were
neutralized by the NaOH?How many moles of HCl were neutralized by
the tablet?

At 295 K and 1.00 atm, assume that 22.0 mL of NO gas reacts with
22.0 mL of
oxygen gas and excess water to produce gaseous nitric acid
according to the
following equation:
2NO(g)+3/2O2(g)+H2O(l)----->2HNO3(g)
If all of the nitric acid produced by this reaction is collected
and then dissolved
into 15.0 mL of water, what would be the pH of the resulting
solution?
(Hint: before you begin, think about which reactant is the limiting
reagent.)

55.0 grams of MnCl2, what weight of HCl will be reacted? 4.) How
many moles of water will be produced when 7.0 mol of...

A 0.250-g sample of a magnesium-aluminum alloy dissolves
completely in an excess of HCl(aq). When the liberated H2(g) is
collected over water at 29 ∘C and 752 torr, the volume is found to
be 345 mL . The vapor pressure of water at 29 ∘C is 30.0 torr. A)
How many moles of H2 can be produced from x grams of Mg in
magnesium-aluminum alloy? The molar mass of Mg is 24.31 g/mol. B)
How many moles of H2 can...

3. Calcium carbonate reacts with HCl according to the following
reaction: CaCO3 + 2 HCl H2 + CO2 + CaCl2 How many grams of CaCO3
are required to react with 14.3 g HCl? Molar masses: HCl 36.5
g/mol; CaCO3 100.09 g/mol;
4.How many grams of solid NaOH
must be weighed to make 300 mL of 0.145 M solution? NaOH
40.0g/mol

You need to prepare 200 mL of 1.00 M NaOH from solid NaOH and
water. you also need to prepare 200 mL of 6.00 M HCl from
concentrated HCl solution.
Describe how you would prepare the NaOH and the HCl solutions.
You need to show th data and calculations for the
standardization.

1) How many moles of acid are there in 17 ml of a 7.1 M HCl
solution?
2) 18 ml of a 1.0 M HCl solution was added to a flask and
titrated against a solution of 3.8 M NaOH. How many ml of the NaOH
solution was required to neutralize the acid?
3) What volume (in liters) of a 2.8 M NaOH solution would
neutralize 4.8 moles of H2SO4 (diprotic)?
4) Using the formula M1V1 =
M2V2, calculate the...
