Project: Modeling potential and kinetic energy
Assignment Summary
For this assignment, you will develop a model that shows a roller coaster cart in four different positions on a track. You will then use this model to discuss the changes in potential and kinetic energy of the cart as it moves along the track.
Background Information
The two most common forms of energy are potential energy and kinetic energy. Potential energy is the stored energy an object has due to its position. Kinetic energy is the energy an object has due to its motion. An object’s kinetic energy changes with its motion, while its potential energy changes with its position, but the total energy stays the same. If potential energy increases, then kinetic energy decreases. If potential energy decreases, then kinetic energy increases.
Potential energy related to the height of an object is called gravitational potential energy. Gravitational potential energy is directly related to an object’s mass, the acceleration due to gravity, and an object’s height.

Answers

Using the concept of Avogadro's number, the number of atoms present is 4.4 * 10^24 atoms.

What is Avogadro's number?

Professor Avogadro provided a nice way of calculating the number of atoms in a molecules by the use of the Avogardro's number. Now we know that 1 mole of a substance contains about 6.02 * 10^23 atoms, molecules ions etc.

Hence;

1 mole of sulfur dioxide contains 6.02 * 10^23 atoms

7.32 moles of sulfur dioxide contains 7.32 moles  * 6.02 * 10^23 atoms/1 mole

= 4.4 * 10^24 atoms.

Two grams of sodium chloride (table salt) were completely dissolved in a glass of water. How would you classify the resulting material?



Group of answer choices

As a mixture.

As a salt compound

As a pure substance

As an element

Answers

Answer:

This is a mixture.

Explanation:

While you can no longer see the salt when it's dissolved, it's still there! It's just in tiny, tiny, invisible to the eye molecules. It's now a mixture of H20 molecules and NaCl molecules in a solution :)

The water doesn't bond to the salt, so it's not a compound.

It's not just one element, it's a mixture of many!

It's not a pure substance since it's NaCl AND H2O.

How many grams are in 3.00 moles of carbon

Answers

Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams

This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

hope this helps have a awesome night/day❤️✨

Explanation:

There are 36 grams in 3.00 moles of carbon.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;

mass (g) = no. of moles (mol) × molar mass (g/mol)

According to this question, 3 moles of carbon was given. The mass can be calculated as follows:

atomic mass of Carbon = 12g/mol

Mass = 12g/mol × 3mol

Mass = 36g.

Therefore, there are 36 grams in 3.00 moles of carbon.

How many moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine

Answers

Answer:

Reaction:

[tex]2Mg + Br_{2} >> 2MgBr[/tex]

Explanation:

Hello there, I think this is a limiting agent question.

When 3 moles of Mg is reacted with 2 moles of Br2, because of ratio, we just need 1.5 moles of Br2, so Mg is a limiting agent.

So 3 moles of Mg will make 3 moles of MgBr

Taking into account the stoichiometry of the reaction, 2 moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine.

The balanced reaction is:

Mg + Br₂ ⇒ MgBr₂

Then, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Mg: 1 mole Br₂: 1 moleMgBr₂: 1 mole

On the other side, the limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to a simple rule of three as follows: if by stoichiometry 1 mole of bromine reacts with 1 moles of magnesium, how much moles of bromine will be needed if 3moles of magnesium react?

[tex]moles of bromine=\frac{1 moles of bromineX3 mole of magnesium}{1 mole of magnesium}[/tex]

moles of bromine=3 moles

But 3 moles of bromine are not available, 2 moles are available. Since you have less moles than you need to react with 3 moles of magnesium, bromine will be the limiting reagent.

Finally, the following rule of three can be applied: if by reaction stoichiometry, 1 mole of bromine forms 1 mole of magnesium bromide, 2 moles of bromine forms how many moles of magnesium bromide?

[tex]moles of magnesium bromide=\frac{2 moles of bromine*1 moles of magnesium bromide}{1 mole of bromine}[/tex]

moles of magnesium bromide= 2 moles

In summary, 2 moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine.

If ONE mole of rocket fuel, ammonium perchlorate, NH4ClO4, is allowed to react with excess Al so that all of the NH4ClO4 is consumed, how many molecules of water will be produced? (All reactants & products are present in a 1:1 ratio.)

Answers

Answer:

9.03×10²³ molecules of H₂O

Explanation:

To solve this, we need to propose the reaction

NH₄ClO₄  →  ammonium perchlorate

Al → Aluminum

Those are the reactants; the reaction is:

6NH₄ClO₄  +  10Al →  5Al₂O₃ + 3N₂ + 6HCl + 9H₂O

Then, water is one of the products. If we see the reaction, is a redox type.

Ratio is 6:9. In conclussion:

6 moles of ammonium perchlorate can produce 9 moles of H₂O

Then 1 mol of salt, may produce (1 . 9)/6 = 1.5 moles of water

Let's count the molecules:

1.5 mol . 6.02×10²³ molecules /mol = 9.03×10²³ molecules of H₂O

A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?

Answers

Answer:

Explanation:

Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.

MM H2O = 18.02 g/mol

MM CaCO3 = 100 g/mol

? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

how many grams of iorn reacts with 71 grams of chlorine to produce 117 grams of sodium chloride

Answers

Answer:

The answer to your question is: 71 g of Chlorine

Explanation:

Na = 46 g

Cl = ?

NaCl = 117 g

Equation

                     2 Na     +     Cl₂   ⇒   2 NaCl          

                     46g              X              117g

If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then

                   mass Na + mass Cl₂  = mass NaCl

                    46 g + X = 117

                    X = 117 - 46

                   x = 71 g of Chlorine

How many liters of bromine gas would 12.3 moles occupy at Standard Temperature and Pressure?

a.) 1 mole/22.4 L
b.) 22.4 mol/1 liter
c.) 22.4 L/1 mole
d.) 1 liter/22.4 mol

Answers

Answer:

c.) 22.4 L/1 mole

Explanation:

Using the general gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

The standard values for a gas are as follows:

Standard pressure of a gas = 1 atm

Standard temperature of a gas = 273K

According to the information in the question, n = 12.3 moles

Using PV = nRT

V = nRT/P

V = 12.3 × 0.0821 × 273/1

V = 275.68 L

Based on this value of volume in liters for 12.3moles of Br gas, the volume per mole at standard temperature and pressure will be 275.68/12.3 = 22.4 Litres per mole. Hence, the answer is 22.4 L/1 mole.

Lithium forms ions with a charge of lt Oxygen forms ions with a charge of 2- in the ionic compound lithium oxide, how many
atoms of lithium will there be if there is 1 atom of oxygen?
HELP ME

Answers

Answer:

There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O

Explanation:

The charge of ions formed by lithium = 1⁺

The charge of ions formed by oxygen = 2⁻

In the ionic compound lithium oxide having 1 atom of oxygen, we have;

For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero

The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the 'n' number of lithium atoms in the lithium oxide compound = 0

∴ 2⁻ + n × 1⁺ = 0

n × 1⁺ = 0 - 2⁻ = 2⁺

n = 2⁺/(1⁺) = 2

n = 2

The number of lithium atoms in the lithium oxide compound, n = 2

Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound
