Shanika is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (orange and green) that start on opposite sides of a large magnet located at the center of a station. Shanika wants to get the largest increase in potential energy she can by moving one car one space to the left or the right. Shanika can move the orange car to point A or point B, or she can move the green car to point C or point D. Which movement should she make? Why will that movement result in the largest increase in potential energy? Describe the magnetic force that will act on the roller coaster car she moves. What should I do for the Green cart?

Answer: hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force.

Explanation:

An atom of ordinary hydrogen consists of one electron and one proton and zero neutrons.

Hydrogen is a chemical element placed at the top of group 1 in the periodic table and is represented by the chemical symbol H and atomic number 1.

A hydrogen atom is the lightest atom of the element in the whole periodic table. Hydrogen exists as a gas of diatomic molecules having the formula H₂ at standard conditions. Hydrogen gas is tasteless, colorless, odorless, non-toxic, and highly combustible.

Hydrogen is constituting roughly 75% of all normal matter and is the most abundant chemical substance in the universe. Most of the hydrogen element on Earth exists in forms like water and organic compounds.  Each atom of hydrogen (¹H) has one proton, one electron, and no neutrons.

Hydrogen element is nonmetallic and easily forms a single covalent bond with most nonmetallic elements, forming compounds like water.

A metal electrode composed of  strong reducing agent will have a greater

electrical potential to push electrons toward the electrode composed of a

weak reducing agent.

Strong reducing agents are compounds which donates or loses electrons

with a corresponding increase in the oxidation state. Weak reducing agents

can also be referred to as oxidizing agents and they accept the electrons

from the strong reducing agents which results in a reduction in the oxidation

state.

The strong reducing agent has a greater electric potential which aids the

electrons being pushed towards the electrodes with a weak reducing agent.

Explanation:

Patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.

Hyperparathyroidism occurs when there is over secretion of parathyroid hormone by the parathyroid glands.

The parathyroid hormone is responsible for the following in the body:

Renal calculi are strong masses of stones deposited in the kidneys or urinary bladder.

When there is excess calcium in the blood due to hyperparathyroidism, the kidneys would be over burdened with the excretion of excess calcium.

That extra calcium in the kidney & the urine leads to kidney stone development ( renal calculi).

Therefore, patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.

Answer:(8.5d) A compound has a formula Mg:(PO.). Which best describes the atoms that make up this compound? A. B. Atom Magnesium (Mg) phosphorus (0) Oxygen (0)

Explanation:

Answer: 82.0 g/mole

Explanation:

Use the units to see that if we divide 1.64 grams by 0.0200 moles, we'll get a number that is grams/mole, the definition of formula mass.

1.64/0.0200 = 82.0 g/mole (3 sig figs)

We can't tell from this alone what the molecular formula might be, but C6H10 (cyclohexene) comes close (82.1 grams/mole).

The formula mass of the compound will be approximately 82.0 g/mol

The formula mass of the compound is the sum of atomic masses of all the atoms in its chemical formula. It is calculated by adding up the atomic masses of the individual elements in the compound, each multiplied by the subscript indicating the number of atoms of that element in the formula.

To find the formula mass of the compound, we'll use the relationship between moles, mass, and molar mass.

Molar mass (in g/mol) = Mass (in g)/Moles

Given:

Mass = 1.64 g

Moles = 0.0200 moles

Let's plug the values and calculate molar mass:

Molar mass = 1.64 g / 0.0200 moles

Molar mass ≈ 82.0 g/mol

The formula mass of the compound is approximately 82.0 g/mol, rounded to three significant figures.

Mr. garcia uses magnets to hold a poster on a steel filing cabinet because a main component of steel is iron.

The chemical element iron has the atomic number 26 and the symbol Fe. It is a metal that is found in group 8 of a periodic table and the first transition series. It makes up a large portion of the planet's outer or inner core and is the most prevalent element on Earth by mass, just ahead of oxygen.

It is the fourth most prevalent element in the crust of the Earth, having been mostly deposited by meteorites inside its metallic state, along with its ores. Iron ores must be processed in kilns or furnaces that may reach 5000 °C (2,730 °F) and higher, which is approximately 500 °C (932 °F) greater than the temperature needed to smelt copper.

The theoretical yield of sodium chloride when 8.3 g of sodium react with 4.5 g of chlorine is 3.30 g

We'll begin calculating the masses of Na and Cl that reacted and the mass of NaCl produced from the balanced equation.

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 g

Molar mass of Cl₂ = 2 × 35.5 = 71 g/mol

Mass of Cl₂ from the balanced equation = 1 × 71 = 71 g

Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol

Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g

SUMMARY

From the balanced equation above,

46 g of Na reacted with 71 g of Cl₂ to produce 117 g of NaCl

From the balanced equation above,

46 g of Na reacted with 71 g of Cl₂

Therefore,

8.3 g of Na will react with = (8.3 × 71)/46 = 12.81 g of Cl₂

From the calculation made above, we can see that a higher amount (i.e 12.81 g) of Cl₂ than what was given (i.e 4.5 g) is needed to react completely with 8.3 g of Na.

Therefore, Cl₂ is the limiting reactant and Na is the excess reactant

From the balanced equation above,

71 g of Cl₂ reacted to produce 117 g of NaCl.

Therefore,

4.5 g of Cl₂ will react to produce = (4.5 × 117)/71 = 3.30 g of NaCl

Thus, the theoretical yield of NaCl produced is 3.30 g

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.
