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.

Answers

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.

If 6 moles of Al2O3 react, how many moles of O2 are produced?

Answer:

18 moles O₂

Explanation:

To convert moles of Al₂O₃ to moles O₂, you first need to determine the balanced reaction. Using the reaction coefficients, you can multiply the starting value by the mole-to-mole ratio of the desired substances.

1 Al₂O₃ ---> 3 O₂ + 2 Al

6 moles Al₂O₃            3 moles O₂

Identify the oxidizing and reducing agents in the following: H2S(aq) + Cl2(g) -> S(s) + 2HCI (aq)

Answers

The oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

What is an oxidizing and reducing agent?

An oxidizing agent is any substance that oxidizes, or receives electrons from another substance and as a result, becoming reduced.

On the other hand, a reducing agent is any substance that reduces or donates electrons to another and as a result becomes oxidized.

According to this reaction; H2S(aq) + Cl2(g) -> S(s) + 2HCI (aq)

H2S accepts electrons from Cl2 and becomes reduced to SCl2 donates electrons to H2S and becomes oxidized to HCl

Therefore, the oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

Explanation:

Alcohols are organic compounds that are composed of the hydroxyl function group ([tex]-\text{OH}[/tex]), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group ([tex]-\text{OH}[/tex]).

According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -e ending of the name of the parent alkane to the suffix -ol.

For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.

Why does the oil in this soup gather into drops instead of dissolving evenly throughout the surface of the water

Answers

The water molecules cannot share intermolecular forces with the oil molecules

The water molecules must do hydrogen, but cannot when they touch the oil molecules

Oil drops do not spread across hot water because the surface tension of hot water is lower than that of oil. The water molecules cannot share intermolecular forces with the oil molecules. Thus the correct option is C.

Oil has a higher surface tension than hot soup. It prevents an oil drop from spreading over the heated soup. The surface tension of oil is lower than that of soup when the soup's temperature drops. As a result, the oil drop begins to spread across the soup.

The cohesive force between oil molecules is less than the adhesive force between oil and water molecules. As a result, water molecules and oil molecules do not mix.

Thus the correct option is C.

Now;

Number of moles of glucose = 2.5g/180 g/mol = 0.014 moles

Since 1 mole of glucose produces 6 moles of water

0.014 moles of glucose produces 0.014 moles * 6 moles/ 1 mole

10.30 Indicate whether each of the following solutions is acidic,
basic, or neutral:
a. [H3O+] = 6.0 × 10-12 M

Answers

Answer:

Basic

Explanation:

The pH scale is measured from 0 to 14.

At the pH scale of 7, a solution is neutral.

Any solution above 7 is basic.

Any solution below 7 is acidic.

Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:

pH = -log[H₃O⁺]

pH = -log(6.0 x 10⁻¹²)

pH = 11.22

As you can see, the solution must be basic because the pH lies within the basic range.

Tin(IV) sulfide, SnS2, a yellow pigment, can be produced using the following reaction.

How is yield calculated?

From the equation of the reaction, the mole ratio of [tex]SnBr_4[/tex] to [tex]Na_2S[/tex] is 1:2.

Mole of 48.1 mL, 0.478 M  [tex]SnBr_4[/tex] = 0.478 x 48.1/100 = 0.023 mols

Mole of 48.8 mL, 0.160 M   [tex]Na_2S[/tex] = 0.160 x 48.8/1000 = 0.0078 moles

[tex]SnBr_4[/tex][tex]Na_2S[/tex] is the limiting reactant.

Mole ratio of  [tex]SnBr_4[/tex]  and [tex]SnS_2[/tex] = 1:1

Equivalent mole of  [tex]SnS_2[/tex] = 0.023 moles

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.

Answers

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.
