Another metal phosphate is iron phosphate. It will behave
similar to calcium phosphate in an acid solution. What is the net
ionic equation including phases for FePO4(s) dissolving in
H3O+(aq)?
1)Another metal phosphate is aluminum phosphate. It will behave
similar to calcium phosphate in an acid solution. What is the net
ionic equation including phases for AlPO4(s) dissolving in
H3O+(aq)?
Express your answer as a net ionic equation.
2)A 75.0-mL volume of 0.200 M NH3
(Kb=1.8×10−5) is titrated with 0.500 M HNO3.
Calculate the pH after the addition of 27.0 mL of HNO3.
3)A 52.0-mL volume of 0.35 M CH3COOH
(Ka=1.8×10−5) is titrated with 0.40 M NaOH.
Calculate the pH...
What is the net ionic equation for:
1) Barium sulfate + nitric acid
2) Calcium phosphate + nitric acid
3) Silver acetate + nitric acid
I got these for the answers but were marked wrong. The teacher
crossed out what was wrong in each, not sure what I did incorrect,
though.
1) BaSO4(s) -> Ba^2+(aq) + SO4^2-(aq) (both products crossed
out)
2) Ca3(PO4)2(s) -> 3Ca^2+(aq) + 2PO4^3-(aq) (2PO4^3-(aq)
crossed out)
3) AgC2H3O2(s) -> Ag+(aq) + C2H3O2^-(aq) (acetate in products
crossed...
Consider the reaction of iron (III) sulfate (aq) and sodium
phosphate (aq) to form iron (III) phosphate (s) and sodium sulfate
(aq).
c. If 2.16 g of iron (III) phosphate are obtained when a student
performed this reaction, what is the percent yield?
d. Is the answer from part C reasonable? Assuming no calculation
errors were made, give a possible explanation for the answer in
part C.
e. If you perform this reaction with 20.00 mL of the 0.250 M...
Pick one of the following questions to answer. Do not repeat answers that have already been stated. No credit will be given for repeated answers. DO NOT answer the question number in its entirety. Answer only what is being asked. 1. Discuss one specific mechanism in which calcium or phosphate is regulated. 2. Discuss one specific agent that affects bone metabolism. 3. Discuss a bone disease that is covered in the powerpoints or textbook and treatment, if any. 4. Discuss a bone fracture that...
5.0 g of calcium phosphate is mixed into 1 L of solution
a) what is the concentration of Ca^2+ and PO4^3-? calculate
b) explain how you could dissolve will calcium phosphate
c) what is the molarity of the solutions, if you were able to
dissolve all of it?
Pure iron metal can be produced by the reduction of iron(III)
oxide with hydrogen gas.
(a) Write the expression for the equilibrium constant (Kc) for
the reversible reaction Fe2 O3(s) + 3H2(g) ⇌ 2Fe(s) + 3H2 O(g) ΔH =
98.7 kJ
b) What will happen to the concentration of each reactant and
product at equilibrium if more Fe is added?
c) What will happen to the concentration of each reactant and
product at equilibrium if H2O is removed?
d) What...
An alloy of iron and carbon was treated with sulfuric acid, in
which only the iron reacts.
if a sample of alloy weighing 2.358g gave home hydrogen which
causes an explosion and generated 1.0368g of water, what is the
percencentage of iron in the alloy? (hint: Hydrogen can react with
oxygen in the air and explode)
Explain the molecular mechanism by which phosphate interferes
with calcium determination.
What is the nature of the compound formed and what two actions
can be performed to eliminate this type of interference?
