What problems might there be if oxygen was very soluble in water?
Water can dissolve oxygen gas. The oxygen that is dissolved in water is used for respiration by plants and animals that dwell in water. Therefore, oxygen gas that has been dissolved in water is crucial for the survival of aquatic creatures and plants.
What is respiration ?During respiration, carbon dioxide is expelled in the opposite direction, back into the environment, while oxygen is moved from the outside environment to the cells within tissues.
The oxygen molecules become trapped between the open spaces between the water molecules as a result of the creation of hydrogen bonds. Water is a polar solvent, as is well known.
Additionally, the oxygen molecules have pi-electrons, which give them a certain amount of polarity because they are sensitive to polar environments.
The majority of aquatic creatures need oxygen for respiration, and our aquatic ecosystems are at risk if there is an oxygen shortage in the water.
Thus, The oxygen that is dissolved in water is used for respiration by plants and animals that dwell in water.

A rigid container of O 2 has a pressure of 340 kPa at a temperature of 713 K. What is the pressure at 273°C ?
Answer:
260 kPa
Explanation:
To answer this problem we can use Gay-Lussac's law, which states that at a constant volume (such as is the case with a rigid container):
P₁T₂=P₂T₁Where in this case:
P₁ = 340 kPaT₂ = 273 °C ⇒ 273 + 273.16 = 546 KP₂ = ?T₁ = 713 KWe input the data:
340 kPa * 546 K = P₂ * 713 KAnd solve for P₂:
P₂ = 260 kPawhy does a mole of silicon weigh a different amount than a mole of carbon?
Answer:
[tex]\boxed {\boxed {\sf Different \ amount \ of \ protons, neutrons, \ and \ electrons}}[/tex]
Explanation:
Remember that a mole is equal to Avogadro's number: 6.022*10²³ atoms. Also, remember that an atom is made up of protons, neutrons, and electrons. Each element has a different amount of each.
If an element has more of these particles in 1 atom, then the atomic mass will be greater, ultimately making the molar mass (mass of 1 mole) greater.
Silicon has 14 protons, electrons, and neutrons, making its atomic mass 28.085 amu and its molar mass 28.085 grams. However, carbon only has 6 of each particle, so its atomic mass is smaller at 12.011 amu and molar mass is 12.011 grams.

2 moles KCl + 3 moles O2 → 2moles KCIO3
Calculate the number of particles of each substance based on the number of moles from the balanced equation
Answer:
KCl ⇒ 1.205x10²⁴ molecules
O₂ ⇒ 1.807x10²⁴ molecules
KClO₃ ⇒ 1.205x10²⁴ molecules
Explanation:
In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states the number of particles in one mol:
In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).So now we multiply the number of moles of each substance by Avogadro's number:
KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ moleculesO₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ moleculesKClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ moleculesgroup of adjacent nucleic acids are a. phosphodiester bond b. peptide bonds c. lnoic bond d. covalent bonds
Answer: A. Phosphodiester bond.
Explanation: "A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. Phosphodiester bonds are central to all life on Earth as they make up the backbone of the strands of nucleic acid."
"The nucleotides in DNA and RNA have three components: a sugar group, a nitrogenous base, and a phosphate group. Adjacent nucleotides in a nucleic acid are joined by a phosphodiester bond."

A net force of 66 newtons accelerates a child at 2.0 m/s? down a smooth playground slide. What is the mass of the
child?
A 130 kg
B68 kg
© 64 kg
D 33 kg
Answer:The answer is D 33
Explanation:
The mass of the child accelerating at 2 m/s² by a net force of 66 N is 33 Kg (Option D)
Relationship between force and accelerationForce is related to acceleration according to the following equation
Force (F) = mass (m) × acceleration (a)
F = ma
With the above formula, we can obtain the mass of the child
How to determine the mass of the child Acceleration (a) = 2 m/s²Force (F) = 66 NMass (m) =?F = ma
66 = m × 2
Divide both side by 2
m = 66 / 2
m = 33 Kg
Thus, the mass of the child is 33 Kg

When a nonmetal gains electrons, it becomes this type of ion.
Answer:
When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. A neutral chlorine atom has seven electrons in its outermost shell.

Which of the following is an example of a situation where work occurs?
A
a glass of water sitting on the counter
B
a leaf resting on a rock
с
a student sitting at a desk
D
a baseball soaring through the air
Answer:
a baseball soaring through the air
Explanation:
According to the passage, “Work occurs whenever something is moved and an object is put into motion.” A baseball soaring through the air is an object in motion.
An example of a situation where work occurs is a baseball soaring through the air. Therefore, option D is correct.
What is work ?Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. In its simplest form, it equals the product of the force's magnitude and the distance traveled for a constant force directed in the same direction as the motion.
Inertia law. Its name derives from an object's propensity to resist any change in motion up until an out-of-balance force acts on it.
A force that opposes motion is friction. Friction occurs when two moving objects come into touch and operates in the opposite direction.
The angle between force and displacement determines the kind of work that is done. Positive work occurs when a force is applied and an object is moved in that direction.
Thus, option D is correct.

What is the percent composition HCN?
Answer:

Explanation:
percent = part/total x 100%
part = ∑ atomic mass of element
hydrogen = 1.008 amu (atomic mass units)carbon = 12.011 amunitrogen = 14.007 amutotal = ∑ molecular mass of compound
= H amu + C amu + Namu
