Answer:
[tex]m_{CO_2}=1.27gCO_2[/tex]
Explanation:
Hello!
In this case, since the combustion of butane is shown below:
[tex]C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O[/tex]
We can evidence the 1:4 and 13/2:4 mole ratio of butane to carbon dioxide and oxygen to carbon dioxide respectively. Thus, in order to compute the maximum amount of carbon dioxide produced in this reaction, we set up the following stoichiometric work:
[tex]m_{CO_2}^{by\ C_4H_{10}}=4.00gC_4H_{10}*\frac{1molC_4H_{10}}{58.12gC_4H_{10}}*\frac{4molCO_2}{1molC_4H_{10}}*\frac{44.01gCO_2}{1molCO_2}=12.11gCO_2\\\\ m_{CO_2}^{by\ O_2}=1.50gO_2*\frac{1molO_2}{32gO_2}*\frac{4molCO_2}{13/2molO_2}*\frac{44.01gCO_2}{1molCO_2}=1.27gCO_2[/tex]
Thus, since oxygen yields the fewest amount of carbon dioxide, we infer the former is the limiting reactant and therefore the maximum amount of carbon dioxide product is 1.27 g.
Best regards!

Glven 4.62 mol of sodium hydroxide, NaOH, how many grams are present?
According to the mole concept , there are 184.8 grams in 4.62 moles of sodium hydroxide.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Number of moles is given as, mass/ molar mass
∴mass=number of moles×molar mass
On substitution, mass= 4.62×40=184.8 g
Thus, there are 184.8 g in 4.62 mole of sodium hydroxide.

Explanation:
Electron affinity is the energy change that results from adding an electron to a gaseous atom(Khan Academy). It is also defined as "the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion" (Wikipedia).
Electron affinity increases from left to right in the periodic table. However, the noble gases possess a complete outermost electron shell.
Hence, electron affinity can be raked from the most negative to the least negative for the three atoms as follows; Br>Ge>Kr

8. A liquid boils when the vapor pressure of the liquid equals the atmospheric pressure on the surface
of the liquid. Using Reference Table H, determine the boiling point of water when the atmospheric
pressure is 90. kPa
Answer:
It is 98 degrees C.
Explanation:
Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the equation PV = C, where C is a constant. Suppose that at a certain instant the volume is 100 cm3, the pressure is 150 kPa, and the pressure is increasing at a rate of 30 kPa/min. At what rate is the volume decreasing at this instant?
Answer:
The volume is decreasing at a rate of 30 cm³/min.
Explanation:
From the question given above, pressure (P) and volume (V) are related by the following equation
PV = C
C => constant
If we make P the subject of the above, we shall have:
P = C/V
From the equation above (i.e P = C/V),
We can say that P is inversely proportional to V. This implies that as P is increasing, V will be decreasing and also, as P is decreasing, V will be increasing.
Considering the question given above, the pressure (P) is increasing at a rate of 30 kPa/min. Therefore, the volume will be decreasing at a rate of 30 cm³/min.

Which of the following molecules is the least polar?
A) H-H
B) H-CI
C) H-F
D) H-I
Answer: A) H-H is least polar
Explanation:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself. The more is the difference in electronegativity, the more polat the bond is.
1. H-H : Electronegativity difference = electronegativity of hydrogen - electronegativity of hydrogen =2.1 -2.1= 0
2. H-Cl : Electronegativity difference = electronegativity of chlorine - electronegativity of hydrogen = 3-2.1 = 0.9
3. H-F : Electronegativity difference = electronegativity of fluorine - electronegativity of hydrogen= 4-2.1= 1.9
4. H-I : Electronegativity difference = electronegativity of iodine - electronegativity of hydrogen= 2.5 -2.1= 0.4
Thus the least electronegativity difference between the bonded atoms is in H-H , this is least polar.

Explanation:
Aluminum sulfate reacts with barium chloride to form the insoluble compound, barium sulfate. The reaction proceeds according to the balanced equation below:
1Al2(SO4)3 + 3BaCl2 → 2AlCl3 + 3BaSO4
Marie reacts 150 g of aluminum sulfate with 200 g of barium chloride in order to produce insoluble barium sulfate for her crystallography studies. Determine the limiting and excess reactants for this reaction.
Molar mass aluminum sulfate: 342.15 g/mol
Molar mass barium chloride: 208.23 g/mol
Molar mass barium sulfate: 233.38 g/mol
Answer: [tex]BaCl_2[/tex] is the limiting reagent and [tex]Al_2(SO_4)_3[/tex] is the excess reagent.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of aluminium sulphate}=\frac{150g}{342.15g/mol}=0.438moles[/tex]
[tex]\text{Moles of barium chloride}=\frac{200g}{208.23g/mol}=0.960moles[/tex]
The balanced chemical reaction is:
[tex]Al_2(SO_4)_3+3BaCl_2\rightarrow 2AlCl_3+3BaSO_4[/tex]
According to stoichiometry :
3 moles of [tex]BaCl_2[/tex] require = 1 mole of [tex]Al_2(SO_4)_3[/tex]
Thus 0.960 moles of [tex]BaCl_2[/tex] will require=[tex]\frac{1}{3}\times 0.960=0.320moles[/tex] of [tex]Al_2(SO_4)_3[/tex]
Thus [tex]BaCl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al_2(SO_4)_3[/tex] is the excess reagent as it is left.

2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂First we convert 9.90 g of Pb(NO₃)₂ into moles, using its molar mass:
9.90 g ÷ 331.2 g/mol = 0.0299 mol Pb(NO₃)₂Then we convert moles of Pb(NO₃)₂ into moles of PbO, using the stoichiometric coefficients:
0.0299 mol Pb(NO₃)₂ * [tex]\frac{2molPbO}{2molPb(NO_3)_2}[/tex] = 0.0299 mol PbONow we convert 0.0299 mol PbO into grams, using its molar mass:
0.0299 mol PbO * 223.2 g/mol = 6.67 g PbOSo 6.67 g is the theoretical yield. With that in mind we calculate the percent yield:
% yield = 5.51 / 6.67 * 100 % = 82.6%So the correct answer is option B.
