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.

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:

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.

Answer:

2.49 M

Explanation:

Step 1: Given data

Step 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

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 =

[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

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]

[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.

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.

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.

Thus,

Solar - sun's rays

Moving water - Hydropower

Plants - Biomass

Nuclear reactions - Geothermal
