A

B

с

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.

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."

What is the ionic charge for the lead ion in PbS2?
Answer:
[tex]\boxed {\boxed {\sf +4}}[/tex]
Explanation:
Lead (Pb) has 2 positive oxidation states, +4 and +2.
Sulfur (S) has 3 oxidation states: +6, +4, and -2. Since lead creates a positive ion, sulfur must be a negative ion to balance the charges.
There are 2 atoms of sulfur, each with a charge of -2. Therefore, their overall charge is -4, because 2* -2= -4.
A compound has a net charge of 0. To achieve this, lead must have a charge of +4 to balance out the -4 charge of sulfur.
Lead has a +4 ionic charge in PbS₂
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.

To determine the concentration of a sodium thiosulfate solution as in this experiment, a student pipetted 25.0 mL of 0.0100 M potassium iodate (KIO3) solution into a 125 mL Erlernmeyer flask. Potassium iodide and sulfuric acid were added as in this experiment. The titration needed 15.21 mL of the sodium thiosulfate to reach the end point. What is the concentration of the sodium thiosulfate solution
Answer:
0.0986M is the concentration of the Na₂S₂O₃ solution
Explanation:
Potassium iodate, KIO₃, reacts with sodium thiosulfate, Na₂S₂O₃, as follows:
KIO₃ + 6Na₂S₂O₃ +5KI + 3H₂SO₄ → 3H₂O + 3K₂SO₄ + 3Na₂S₄O₆ + 6NaI
To solve this question we must find the moles of sodium thiosulfate that reacts as follows:
Moles KIO₃:
0.0250L * (0.0100mol / L) = 2.5x10⁻⁴moles KIO₃
Moles Na₂S₂O₃:
2.5x10⁻⁴moles KIO₃ * (6mol Na₂S₂O₃ / 1mol KIO₃) = 1.5x10⁻³ moles Na₂S₂O₃
Molar concentration:
1.5x10⁻³ moles Na₂S₂O₃ / 0.01521L =

The energy exists in many different forms. Each form of energy can be converted or changed into the other forms. The geothermal energy denotes the thermal energy.
What is solar energy?The energy produced from the sun is called the solar energy. The heat and light which come from the sun is the solar energy. The solar energy play an important role in reducing the emissions of green house gases and also control the climate change.
The biomass is known as the fuel obtained from the organic matter waste of the living organisms such as plant waste, animal waste and municipal wastes. It is the fuel developed from plants.
The hydropower is the largest source of renewable energy which uses the moving water to produce electricity. The energy which is generated from the heat within the earth is called the Geothermal energy.

150. g of aluminum chloride in 0.450 liters of solution, what is the concentration? (any examples are helpful, thank you)
Answer:
2.49 M
Explanation:
Step 1: Given data
Mass of AlCl₃: 150. gVolume of solution: 0.450 LStep 2: Calculate the moles AlCl₃ (solute)
The molar mass of AlCl₃ is 133.34 g/mol.
150. g × 1 mol/133.34 g = 1.12 mol
Step 3: Calculate the molar concentration of AlCl₃
Molarity is equal to the moles of solute divided by the liters of solution.
M = 1.12 mol/0.450 L = 2.49 M

The Kb for hydroxylamine, HONH2, is 1.1 x 10 -8
. What would be the pH of a solution
prepared by placing 1.34 g of HONH2 in 0.500 L of water?
Answer:
pH = 9.475
Explanation:
Hello there!
In this case, according to the basic ionization of the hydroxylamine:
[tex]HONH_2+H_2O\rightarrow HONH_3^++OH^-[/tex]
The resulting equilibrium expression would be:
[tex]Kb=\frac{[HONH_3^+][OH^-]}{[HONH_2]} =1.1x10^{-8}[/tex]
Thus, we first need to compute the initial concentration of this base by considering its molar mass (33.03 g/mol):
[tex][HONH_2]_0=\frac{1.34g/(33.03g/mol)}{0.500L} =0.0811M[/tex]
Now, we introduce [tex]x[/tex] as the reaction extent which provides the concentration of the hydroxyl ions to subsequently compute the pOH:
[tex]1.1x10^{-8}=\frac{x^2}{0.0811-x}[/tex]
However, since Kb<<<<1, it is possible to solve for [tex]x[/tex] by easily neglecting it on the bottom to obtain:
[tex]x=[OH^-]=\sqrt{1.1x10^{-8}*0.0811}= 2.99x10^{-5}[/tex]
Thus, the pOH is:
[tex]pOH=-log(2.99x10^{-5})=4.525[/tex]
And the pH:
[tex]pH=14-4.525\\\\pH=9.475[/tex]
