energy to raise temperature is 590 J
Given:
mass of silver sample = 0.5 kg
initial temperature = 200 k
final temperature = 205 k
specific heat of silver = 236 j/kgk
To Find:
energy to raise temperature
Solution: The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.
Q = cmΔt
where c= constant of proportionality, called specific heat capacity of the body
Q = mass x specific heat x ∆t
= 0.5 x 236 x ( 205-200 )

In your reaction you started with a solution that was approximately 8 M acetic acid and 4 M isopentyl alcohol. Use the equilibrium expression for this reaction to calculate the final concentrations of water, isopentyl acetate, isopentyl alcohol, and acetic acid (you'll need to use the quadratic equation to solve this expression) assuming that the equilibrium constant is 4.2. Calculate the percent yield of isopentyl acetate to which this value would correspond.
The final concentrations of water, isopentyl acetate, isopentyl alcohol, and acetic acid obtained on using equilibrium expression are 3.4M, 3.4M, 0.6M , 4.6M
Using ICE table:-
Acetic acid + Isopentyl alcohol ------> Isopentyl acetate + water
I 8M 4M 0 0
C 8-x 4-x +x +x
E 8-x 4-x +x +x
Equilibrium constant (Keq) = 4.2
On using the equilibrium expression -
Keq = [Product] / [Reactant]
Keq = x^2 / (8-x) (4-x )
4.2 = x^2 / 32 - 8x - 4x + x^2
x = 3.4
Concentration of acetic acid = 8-x = 8-3.4 = 4.6M
Concentration of isopentyl alcohol = 4-x = 4-3.4 = 0.6M
Concentration of isopentyl acetate = x = 3.4M

How many grams of CO2 will be produced when 8.50 g of methane react with 15.9 g of O2, according to the following reaction? CH4(g) +2 O2(g) = CO2(g) +2 H2O(g)
Taking into account the reaction stoichiometry, 10.93 grams of CO₂ are formed when 8.50 g of methane react with 15.9 g of O₂.
Reaction stoichiometryIn first place, the balanced reaction is:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
CH₄: 1 mole O₂: 2 molesCO₂: 1 moleH₂O: 2 molesThe molar mass of the compounds is:
CH₄: 16 g/moleO₂: 32 g/moleCO₂: 44 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
CH₄: 1 mole ×16 g/mole= 16 gramsO₂: 2 moles ×32 g/mole= 64 gramsCO₂: 1 mole ×44 g/mole= 44 gramsH₂O: 2 moles ×18 g/mole=36 gramsLimiting reagentThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
Limiting reagent in this caseTo determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 16 grams of CH₄ reacts with 64 grams of O₂, 8.50 grams of CH₄ reacts with how much mass of O₂?
[tex]mass of O_{2} =\frac{8.50 grams of CH_{4}x64 grams of O_{2} }{16grams of CH_{4}}[/tex]
mass of O₂= 34 grams
But 34 grams of O₂ are not available, 15.9 grams are available. Since you have less mass than you need to react with 8.50 grams of CH₄, O₂ will be the limiting reagent.
Mass of CO₂ formedThe following rule of three can be applied: if by reaction stoichiometry 64 grams of O₂ form 44 grams of CO₂, 15.9 grams of O₂ form how much mass of CO₂?
[tex]mass of CO_{2} =\frac{15.9 grams of O_{2}x44 grams of CO_{2} }{64grams of O_{2}}[/tex]
mass of CO₂= 10.93 grams
Then, 10.93 grams of CO₂ are formed when 8.50 g of methane react with 15.9 g of O₂.

To calculate the moles, we use the equation:
4NH3(g) + 3 O2 (g) ---> 2 N2 (g) + 6 H2O (g) ....(1)
For ammonia:
Putting values in above equation, we get:
Moles of ammonia = 7.00 x 1022 / 6.023 * 10 ^23 = 0.116 mol
Moles of oxygen = 6.00 x 1022 / 6.023 * 10 ^23 = 0.099 mol
For the reaction:
4NH3(g) + 3 O2 (g) ---> 2 N2 (g) + 6 H2O (g)
By Stoichiometry of the reaction,
4 moles of ammonia combine with 3 moles of Oxygen
Thus 0.116 moles of ammonia will combine with= 3/4 * 0.116 = 0.087 of oxygen
Thus ammonia is the limiting reagent as it limits the formation of product.
4 moles of ammonia produces 2 moles of nitrogen
0.132 moles of ammonia will produce=2/4 * 0.116 = 0.058 of nitrogen

It takes 38. 6 kj of energy to vaporize 1. 00 mol of ethanol (mw: 46. 07 g/mol). What will be δssys for the vaporization of 11. 0 g of ethanol at 78. 4 °c?
Answer:
9.21 kJ is the enrgy required to vaporize 11.0 grams of ethanol.
Explanation:
Energy of vaporization can be stated as 38.6 kj/mole for ethanol. ["It takes 38. 6 kj of energy to vaporize 1. 00 mol of ethanol"]
11.0 grams of ethanol is not 1 mole. Calculate the moles of ethanol by dividing t=it's mass by its molar mass:
(11.0 grams)/(46.07 g/mole) = 0.2388 moles ethanol
(0.2388 moles ethanol)*(38.6 kj/mole) = 9.21 kJ is the enrgy required to vaporize 11.0 grams of ethanol.

What is the mass in grams of the excess Al remaining after the partial reaction of 18.3 g Al with 113 g I₂?
2 Al(s) + 3 I₂(g) → 2 AlI₃(g)
Answer:

Explanation:
To find the excess mass of Al, you need to (1) convert grams I₂ to moles I₂ (via molar mass), then (2) convert moles I₂ to moles AlI₃ (via mole-to-mole ratio from equation coefficients), then (3) convert moles AlI₃ to grams AlI₃ (via molar mass). Now that you have the actual amount of AlI₃ produced, you need to (4) convert grams AlI₃ to moles AlI₃ (via molar mass), then (5) convert moles AlI₃ to moles Al (via mole-to-mole ratio from equation coefficients), and then (6) convert moles Al to grams Al (via molar mass). Now that you know the amount of Al actually needed to produce the product, you need to (7) find the excess mass of Al.
Molar Mass (Al): 26.982 g/mol
Molar Mass (I₂): 2(126.90 g/mol)
Molar Mass (I₂): 253.8 g/mol
Molar Mass (AlI₃): 26.982 g/mol + 3(126.90 g/mol)
Molar Mass (AlI₃): 407.682 g/mol

Noble gases have __ values of ionization energy due to their complete outermost shells
Answer:
high
Explanation:
The energy needed to ionize a neutral atom is known as ionization energy. An atom must have one or more electrons removed from its valence shell in order to get ionized and become a cation. Alternately, you must produce an anion by adding one or more electrons to the valence shell. The energy needed for ionization will be lower the fewer electrons are supplied or withdrawn. As a result, atoms having an incomplete valence shell have a tendency to ionize more quickly and with less energy. However, entire valence shell atoms will require a large amount of ionization energy. As a result, noble gases need significant energy to ionize since they contain a full valence shell, are extremely stable, and do not tend to ionize easily.

4- The equilibrium constant for the reaction A (g) B (g) is 10. A reaction mixture initially contains [A]
The initial concentration in the reaction mixture will contain [A] = 0.1 M and [B] = 1.0 M
Below is the reaction
A(g) → B(g)
And the equilibium constant will be explained in terms of [A] and [B]:
Keq = 10 = [B]/[A]
If the first conditions are that [A] = 1.1 M and [B] = 0.0 M, the conditions at equilibrium is:
[A] = 1.1M - x
[B] = 0.0M + x
Now we rewrite Keq:
Keq = 10 = [0.0 +x] / [1.1 -x]
at the end we got it for x:
10 = [0.0 +x] / [1.1 -x]
10 * (1.1-x) = x
11 - 10x = x
11 = 11x
x = 1
equilibrium, the concentrations are:
[A] = 1.1 M - 1 = 0.1 M
[B] = 0.0 M + 1 = 1.0 M
Thus, the concentration of A is 0.1 M and the concentration of B is 1M.
