The reaction between 96.7 g of fes2 and 55.0 l of o2 produced the volume of so2 (at stp) (at 398 k and 1.20 atm). Fes2's molar mass is 119.99 g/mol, which is equivalent to 32.94 L.
FeS2 weighs 96.7 g.
0.806 mol of FeS2 is equal to 96.7 g of mass divided by 119.99 g of molar mass.
----------------
Given 55.0 L of oxygen. We need to find the volume of Oxygen at STP as we need to determine the volume of SO2 at STP.
Hence, we use the equation, P1V1/T1 = P2V2/T2
(1.20 x 55.0) / 398 = (1.0 x V2) / 273
V2 = 45.27 L
Thus, volume of oxygen = 45.27 L
----------------------
Now, we need to find moles of oxygen using the equation PV = nRT
(1.0 x 45.27) = n (0.0821 x 273)
n = 2.02 mol
-------------------
Thus, the reactants we have are
Moles of FeS2 = 0.806 mol
Moles of oxygen = 2.02 mol
Now, we need to find the limiting reagent. In order to find the limiting reagent we need to divide the moles we found with the respective stoichiometric coefficients.
Thus, moles of FeS2 = 0.806 mol / 4 = 0.2015 mol
Moles of O2 = 2.02 mol / 11 = 0.184 mol.
As, the moles of O2 are less than that of FeS2, O2 is the limiting reagent.
Hence, we use moles of O2(2.02 mol) to find the SO2 produced.
From the chemical equation, it is clear that 11 mol of O2 produces 8 mol of SO2.
Thus, 2.02 mol of O2 produces = (2.02 mol O2) x (8 mol SO2 / 11 mol O2) = 1.47 mol of SO2
Using PV = nRT, let us find volume of SO2.
(1.0)(V) = 1.47 x 0.0821 x 273
V = 32.94 L of SO2 is produced.

The balanced complete ionic equation for the reaction between Cs₃PO₄ and AgNO₃ is:
Cs₃PO₄(aq) + 3Ag⁺(aq) + 3NO₃⁻(aq) → 3Ag₃PO₄(s) + 3NO₃⁻(aq) + 3Cs⁺(aq)
Ionic equations are defined as the balanced chemical equations that represent the species (ions or molecules) that are involved in a reaction.
In this reaction:
Cs₃PO₄(aq) + 3Ag⁺(aq) + 3NO₃⁻(aq) → 3Ag₃PO₄(s) + 3NO₃⁻(aq) + 3Cs⁺(aq)
Cs₃PO₄ (cesium phosphate) and AgNO₃ (silver nitrate) are mixed in aqueous solution. The cesium phosphate dissociates into its constituent ions, Cs⁺ and PO₄³⁻.
The silver nitrate dissociates into Ag⁺ and NO₃⁻ ions. The Ag⁺ ions react with the PO₄³⁻ ions to form solid silver phosphate (Ag₃PO₄), which is insoluble in water. The Cs⁺ and NO₃⁻ ions remain in solution.
Therefore, Cs₃PO₄(aq) + 3Ag⁺(aq) + 3NO₃⁻(aq) → 3Ag₃PO₄(s) + 3NO₃⁻(aq) + 3Cs⁺(aq) is the balanced complete ionic equation shows that a reaction takes place between cesium phosphate and silver nitrate to form solid silver phosphate and aqueous cesium and nitrate ions.

The procedures tells a student to measure 7.55 ml of solution 1 but the student measures 11.89 ml of solution 1. The percent by volume of extra liquid measure by the student added is 36.50%.
The percent by volume for any solution is calculated as
%(v/v)=(volume of solute/volume of solution)×100
In the given problem, the volume of solution is 11.89 ml and the volume of the solute is
volume of solute=(11.89-7.55)ml
volume of solute=4.34ml
We cannot consider the volume used to measure by procedure because the total volume is increased by extra addition of the solute. Plug all values in the formula
%(v/v)=(4.34 ml/11.89 ml)×100
%(v/v)=0.36501×100
%(v/v)=36.501%

The periodic table is an arrangment of the chemical elements, ordered by atomic number, into families, and by doing so illustrates the periodic properties of the elements. Considering the organization of the periodic table, which element would make a good conductor of electricity? what properties of that element would support this choice?.
The properties of that element is Copper, Cu.
A solid metal that is ductile and malleable.
Ductility and malleability are properties of metals with specific properties. It is the properties of ductility and formability that aid in the deformation of metals.
Ductility is the ability of a material to stretch without being damaged. A ductile metal can be stretched into a wire. An example is copper wire.Formability is the property of a material to deform under pressure. A malleable metal can be rolled or stamped into sheet. An example is aluminum foilIn metals, the two properties, formability and ductility, do not always correlate. For example, gold is both malleable and malleable, and lead is only malleable.
Therefore, The properties of that element is Copper, Cu.
