(a)
Interpretation:
The balanced chemical equations for the 4
Concept introduction:
A chemical equation is said to be balanced if there are equal number of atoms of same elements present on both sides of the reaction arrow.
(b)
Interpretation:
The mass of lime in kg needed for the removal of phosphorus from 104 holding tanks containing contaminated water needs to be determined.
Concept introduction:
According to
Here, m is mass and M is molar mass.
The density of a substance is defined as mass per unit volume. It is mathematically represented as follows:
Here, m is mass and V is volume of the substance.

- Use the appropriate tables to calculate H for (a) the reaction between MgC03(s) and a strong acid to give Mg2+(aq), CO2(g), and water. (b) the precipitation of iron(III) hydroxide from the reaction between iron(III) and hydroxide ions.arrow_forwardI need some help please!arrow_forwardThe aluminum in a 1.2 g sample of impure ammonium aluminum sulfate was precipitated with aqueous ammonia. The precipitate was filtered and ignited at 1000 oC to give anhdrous Al2O3, which weighed 0.1798 g. Express the result of this analysis in terms of % NH4Al(SO4)2 and % Al2O3 (Molar mass of Al2O3 =101.96 g/mol, Molar mass of NH4Al(SO4)2= 237.15 g/mol)arrow_forward
- A pollutant in smog is nitrogen dioxide, NO2. The gas has a reddish brown color and is responsible for the red-brown color associated with this type of air pollution. Nitrogen dioxide is also a contributor to acid rain because when rain passes through air contaminated with NO2, it dissolves and undergoes the following reaction: 3NO2(g) + H₂O → NO(g) + 2H+ (aq) + 2NO3(aq). In this reaction, which element is reduced and which is oxidized? His both reduced and oxidized. O is oxidized and H is reduced. O is oxidized and N is reduced. ON is both reduced and oxidized. N is oxidized and His reduced. N is oxidized and O is reduced.

In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed. The reaction for this process is below: 5 Ca(OH)2 (aq) + PO43- (aq) → Ca5OH(PO4)3 (s) + OH- (aq) a) If 3.00 mL of 0.100 M calcium hydroxide is mixed with 4.00 mL of an aqueous solution of 0.0800 M phosphate ions (PO43-). What is the mass of Ca5OH(PO4)3 that can be isolated from the reaction? b) How many moles of the excess reactant remains unreacted? c) What is the concentration of the hydroxide ions in this solution? d) What is the mass of calcium (in grams) that can be recovered?arrow_forward
