You drink part of your bottle of water, leaving 160 g in the bottle. When you purchased the water, it had a temperature of 10oC. After carrying the bottle around for awhile, you take a sip and find that the water is an unpleasantly warm 35oC. How much heat energy did the water left in the bottle absorb? Water has a specific heat capacity of 4.2 J/(g * oC).
The energy that the water in the bottle absorbed is obtained as 16800 J.
What is the specific heat capacity?The specific heat capacity of the water refers to the energy that is required to raise the temperature of 1Kg of the water by 1 degree.
Now we have the following;
mass (m) = 160 g
temperature change dT = ( 35oC - 10oC)
specific heat capacity (c)= 4.2 J/(g * oC).
Now;
H = mcdT
H = 160 g * 4.2 J/(g * oC) * ( 35oC - 10oC)
H = 16800 J

Skunks have scent glands that allow the animals to give off an unpleasant odor when they are frightened or uncomfortable.
What function do the scent glands have?
A.
They act as a propulsion system to propel the skunk away from predators.
B.
They attract other skunks to mate with.
C.
They protect skunks against predators.
D.
They kill insects and small animals for the skunks to eat.
Answer:
Some use them to mark their territory, while others use them as skunks do — as a defense mechanism to protect them from predators. Some animals are even named for their odor-producing ability.29 Mar 2021
Explanation:
Skunks have two glands, one on each side of the anus. These glands produce the skunk's spray, which is a mixture of sulfur-containing chemicals such as thiols (traditionally called mercaptans), which have an offensive odor. The thiols also make their spray highly flammable.

Sodium bicarbonate, NaHCO3 ( MW 84.007 g/mol), is commonly known as baking soda. Sodium bicarbonate is a solid crystalline and appears as a white powder. Sodium bicarbonate has a pH of 8.3 at 77 deg F. Sodium bicarbonate can be easily be converted to sodium carbonate, Na2CO3 ( MW 105.988 g/mol) by decomposition to produce H2O and CO2. This can be accomplished by placing the sample in the oven at 176 deg F.
Unbalanced chemical equation:
NaHCO3 (s) + Heat --> Na2CO3 (s) + H20 (g) + CO2 (g)
Write the balanced chemical equation. Calculate yield of the decomposition reaction. Make sure to show your work.
Based on the law of conservation of mass, the expected yield of the decomposition reaction is 100% which is equal to the mass of the reactant.
What mass of products are formed when 1 mole of sodium bicarbonate is decomposed by heat?According to the law of conservation of mass, the mass of products formed when 1 mole of sodium bicarbonate is decomposed by heat will be equal to the mass of one mole of sodium bicarbonate.
The balanced equation of the reaction is given below:
2 NaHCO₃ (s) + Heat --> Na₂CO₃ (s) + H₂0 (g) + CO₂ (g)Molar mass of NaHCO₃ = 84. 0 g/mol
Molar mass of Na₂CO₃ = 106 g/mol
Molar mass of H₂0 = 18 g/mol
Molar mass of CO₂ = 44 g/mol
Based on the mole ratio as given in the equation of reaction,
mass of Na₂CO₃ produced = 1/2 * 106 = 53 g
mass of H₂O produced = 1/2 * 18 = 9 g
Mass of CO₂ produced = 1/2 * 44 g/mol = 22 g
Total mass of products = 53 + 9 + 22 = 84.0 g
Therefore, the yield of the decomposition reaction is equal to the mass of the reactant.

O₂ in the following chemical reaction?
4 NH3(g) + O₂ (g) → 2 N₂H4 (g) + 2 H₂O(g)
AH = -286 kJ/mol
Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)

The empirical formula of a compound that has the following percent composition; 81.68% carbon and 18.32% hydrogen is C2H5.
How to calculate empirical formula?The empirical formula is a notation indicating the ratios of the various elements present in a compound, without regard to the actual numbers.
The empirical formula of a compound that has 81.68% carbon and 18.32% hydrogen can be calculated as follows:
81.68% C = 81.68g 18.32% H = 18.32gFirst, we convert mass to moles;
C = 81.68g ÷ 12g/mol = 6.81mol H = 18.32 ÷ 1g/mol = 18.3molNext, we divide each mole value by the smallest (6.81mol)
C = 6.81 ÷ 6.81 = 1H = 18.32 ÷ 6.81 = 2.7We multiply each ratio by 5 to make an whole number:
C = 1 × 2 = 2H = 2.7 × 2 = 5.4 = 5Therefore, the empirical formula of a compound that has the following percent composition; 81.68% carbon and 18.32% hydrogen is C2H5.

Do not type units with your answer
Answer:
776 L H₂O
Explanation:
To find the volume, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
To find the volume of water vapor, you need to (1) convert grams C₅H₁₂ to moles C₅H₁₂ (via molar mass), then (2) convert moles C₅H₁₂ to moles H₂O (via mole-to-mole ratio from reaction coefficients), then (3) calculate volume H₂O (via Ideal Gas Law). The final answer should have 3 sig figs.
(Step 1 & Step 2)
Molar Mass (C₅H₁₂): 5(12.011 g/mol) + 12(1.008 g/mol)
Molar Mass (C₅H₁₂): 72.151 g/mol
1 C₅H₁₂ (g) + 8 O₂ (g) -----> 5 CO₂ (g) + 6 H₂O (g)
273.36 g C₅H₁₂ 1 mole 6 moles H₂O
----------------------- x ---------------- x ----------------------- = 22.7 moles H₂O
72.151 g 1 mole C₅H₁₂
(Step 3)
P = 1.01 atm R = 0.0821 L*atm/mol*K
V = ? T = 420 K
n = 22.7 moles
PV = nRT
(1.01 atm)V = (22.7 moles)(0.0821 L*atm/mol*K)(420 K)
(1.01 atm)V = 783.856
V = 776 L
Without units, your answer would be 776.

Allyl sulfide, C6H10S, is a compound that has the odor of garlic. How many moles of Allyl sulfide are in 125 g?
Considering the definition of molar mass, 1.096 moles of Allyl sulfide are in 125 g.
Definition of molar massThe molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.
Molar mass of C₆H₁₀SIn this case, you know the molar mass of the elements is:
C= 12 g/moleH= 1 g/moleS= 32 g/moleSo, the molar mass of the compound C₆H₁₀S is calculated as:
C₆H₁₀S= 6× 12 g/mole + 10× 1 g/mole + 32 g/mole
Solving:
C₆H₁₀S= 114 g/mole
Moles in 125 g CH₂Cl₂Next, you can apply the following rule of three: If by definition of molar mass 114 grams of the compound are contained in 1 mole, 125 grams of the compound are contained in how many moles?
[tex]amount of moles=\frac{125 grams x 1 mole}{114 grams}[/tex]
amount of moles= 1.096 moles
Finally, 1.096 moles of Allyl sulfide are in 125 g.
