The complete balanced equation os Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
First, calculate the number of moles of both reactants as follows:
Moles of Fe2O3 = Amount of Fe2O3 / molar mass
Moles of Fe2O3 =22.00 g / 159.69 g/mol = 0.138 mol
Moles of CO = Amount of CO / molar mass
Moles of CO =14.42 g / 28.01 g/mol = 0.515 mol
Now determine the limiting agent as follows:
The limiting reagent is a substance that limits the amount of product in the reaction. This limiting agent is completely consumed in the reaction.
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
0.138 mol Fe2O3 x 3 mol CO / 1 mol Fe2O3 = 0.414 mol CO
Here Fe2O3 is a limiting agent and CO is present in excess. 0.414 mol CO used thus calculate the remaining mol of CO as follows:
0.515 mol CO - 0.414 mol CO = 0.101 mol CO.
Mass of CO = 0.101 mol CO x 28.01 g/mol = 2.83 g CO
2.83 g CO of the excess reactant is left.

What is the normality of a solution of sulfuric acid (H2SO4) that containing 86 g
per liter of solution?
Normality of a solution of sulfuric acid (H2SO4) that containing 86 g
per liter of solution is 1N
What is normality?The gram equivalent weight of a solute per liter of solution is what is known as a solution's normalcy. The comparable concentration is another name for it. The units of concentration are denoted by the symbols N, eq/L, or meq/L (= 0.001 N). A hydrochloric acid solution's concentration, for instance, could be stated as 0.1 N HCl. The reactive capacity of a specific chemical species is measured by gram equivalent weight or equivalent (ion, molecule, etc.). Utilizing the chemical species' molecular weight and valence, the equivalent value is calculated. The only concentration unit that is reaction-dependent is normality.
g equivalent mass of H2SO4 = 86g
Volume of solution in liter = 1 l
number of g equivalent of H2SO4 = 86/86 = 1
Normality = number of g equivalent/ volume of solution in liter
N = 1 / 1
Normality = 1 N

1. Outline a synthesis showing the necessary reagents and intermediate molecules for the following
transformation. For carbon sources, use alkyl halides with 4 or fewer carbons. You will need to use
more than one reaction.
A synthesis showing the necessary reagents and intermediate molecules for carbon sources, use alkyl halides with 4 or fewer carbons is zinc and copper pair in alcohol to reduced alkyl halide.
Which alkyl halide is more reactive ?The Zn/Cu pair in alcohol is used to reduce alkyl halides. In alcohol, the Zn/Cu pair substitutes hydrogen for the halide of an alkyl halide to generate hydrocarbons. The Zn/Cu combination produces methane in alcohol by taking the iodine out of methyl halide and adding hydrogen.
Thus, a synthesis showing the necessary reagents and intermediate molecules for carbon sources, use alkyl halides with 4 or fewer carbons is zinc and copper pair in alcohol to reduced alkyl halide. Alkyl iodide is more reactive.

One mole of an ideal gas is expanded from a volume of 1.00 liter to a volume of 8.93 liters against a constant external pressure of 1.00 atm. How mush work (in joules) is performed on the surroundings?
W = Pexternal(ΔV),W = (1 atm) 8.93 L - 1 L)(101.3 J/1 L·atm)= 803.309J. W. Work, pressure, and volume are directly correlated using a formula. W = Pexextr(V) Consequently, the environmental work is 803.309J. W
How do volume and value work?Market share comes in two flavors: value and volume. The business's overall shares of its total accumulated sector sales serve to define a value market share. On the other hand, a volume market share refers to the precise number of units that an entity markets relative to the total number of units that are sold in the market.
W = quantity of work completed =?
1.00 atm of pressure is P.
1.00 L is the initial volume.

Name the following alkyl halides
The IUPAC nomenclature of compound 1 is 5-bromo-2-methylchloridepent-2-ene and the name for structure 2 is 5-iodo-hex-2-ene
IUPAC nomenclature is the method of naming the organic chemical compounds by following certain rules and criteria given by IUPAC.
This nomenclature is based on naming a molecules longest chain of carbons connected by single bonds, whether in a continuous or in ring form. Everything else like multiple bonds or atoms are other than carbon and hydrogen are indicated by prefixes or suffixes according to a specific set of priorities.
In structure 1 we can see that we are number so that the double bond that is present gets the least priority and then the naming is done in the alphabetic order. so the name is 5-bromo-2-methylchloridepent-2-ene
In structure 2 the same thing is followed and the name of the structure is

What quantity in moles of chlorine gas at 120.0 °C and 33.3 atm would
occupy a vessel of 36.5 L?
The number of chlorine moles present in the vessel are 37.67 mol.
What are moles?
Moles are the number of substances present in a system which consists of entities like ions, atoms, or molecules as much as atoms in the weight of pure carbon which is 12 grams. It is the SI unit of amount of substance.
One mole of a substance is equal to the Avogadro Number which is equal to 6.022×10²³.
According to Ideal gas law,
PV=nRT where,
P= Pressure
V= Volume
n= number of moles
R= Ideal gas constant
T= temperature (in Kelvin)

The volume of the given ball is 21 L.
Pressure = 1.0 atm
no. of moles = 0.85 mol
Temperature = 25°C = (25+273) K = 298 K.
we will use the ideal gas equation,
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Let's substitute the values into the above formula,
1.0 x V = 0.85 x 0.0821 x 298
V = 20.7 [tex]\approx[/tex] 21 L.

What is reflex action?Reflex action is generated by our body by the sudden action to for sense of touch or other stimulants. For example, if touch a very hot body, we will take our hand within second and this is resulted by the action of neuron and is called the reflex action.
The movement of hands and legs are controlled by the motor neurons. If we touch any stimulant sensory neurons pass signals to the motor neuron and a signal containing the information of action is returned to the sensory neurons of our hand.
Here, the communication between sensory neuron and motor neuron is facilitated by interneurons. Thus, in this picture the motor neuron be the interneuron and interneuron be the motor neuron. Thus option A and D are correct.
