They apply a cumulative force of 1080 N to push the car 21,800 cm to the nearest fuel station. Determine the work done on the car.
Answer:
2.35 × 10⁵ J
Explanation:
Renatta Gass is out with her friends. Misfortune occurs and Renatta and her friends find themselves getting a workout. They apply a cumulative force of 1080 N to push the car 21,800 cm to the nearest fuel station. Determine the work done on the car.
Step 1: Given data
Force applied on the car (F): 1080 NDistance traveled by the car (d): 21,800 cmStep 2: Convert "d" to meters
We will use the conversion factor 1 m = 100 cm.
21,800 cm × 1 m/100 cm = 218 m
Step 3: Calculate the work done (W)
We will use the following expression.
W = F × d
W = 1080 N × 218 m = 2.35 × 10⁵ J

Compare and contrast conventional and convectional oven
Answer:
The conventional oven and the convection oven are confused with each other due to their similar look and style, and a lot of their functioning is quite the same as well.
The conventional ovens have existed for over half a century, and have derived their functioning from traditional ovens that are over 4,000 years. They function with a bottom-up heat transfer from a fixed burner source.
The convection ovens were made recently as a way to get better heating results for all types of dishes and recipes, with the introduction of a fan system along with an exhaust which allows the circulation of hot air around the cavity of the oven.

A. 1 mole of any element contains 6.02 x 10^23
_______
B. 1 mole of any compound contains 6.02 x 10^23
_______
Answer:
A. 1 mole of any element contains 6.02 x 10^23 atoms.
B. 1 mole of any compound contains 6.02 x 10^23 molecules.
Explanation:
:)
Taking into account the definition of Avogadro's Number, the correct answers are:
1 mole of any element contains 6.023×10²³ atoms1 mole of any compound contains 6.023×10²³ moleculesYou have to know that Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.
Avogadro's number applies to any substance, because the number of elementary units in a mole of substance is, by definition, a constant that does not depend on the material or the type of particle considered.
So, in this case, the correct answers are:
1 mole of any element contains 6.023×10²³ atoms1 mole of any compound contains 6.023×10²³ moleculesLearn more about Avogadro's Number:

What is the chemical formula and net ionic equations for all three solutions.
Answer:
See answer below
Explanation:
As you are asking for chemical formula and ionic equation, then, I will assume that after the station #5 below, are the solutions you are requiring.
You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.
Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.
1. Solution 1 Barium Chloride:
In this case we have Barium on one side, and Chlorine on the other side, the symbol for those are Ba and Cl. As Barium have the +2 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Chlorine it will be -1, so, the formula will be:
BaCl₂
And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:
Ba²⁺ + 2Cl⁻ ------> BaCl₂
2. Solution 2 and 3, Copper (II) nitrate and Copper(II) sulfate:
In this case I will work with both, because both of the solution have copper and the only difference is the anion, which is nitrate in one, and sulfate on the other. In this cases, we have a tertiary salt, The copper's symbol is Cu, and is working with it oxydation state +2. Nitrate is an anion and have the formula NO₃ working with the oxydation state -1. Sulfate is SO₄ and works with oxydation state -2 instead.
The chemical formula and ionic equation for both will be:
Copper(II) nitrate: Cu(NO₃)₂
Copper(II) sulfate: CuSO₄
And the net equations:
Copper nitrate: Cu²⁺ + 2NO₃⁻ ------> Cu(NO₃)₂
Copper sulfate: Cu²⁺ + SO₄²⁻ -------> CuSO₄

How many moles of helium gas are present in 120 liters at STP
a. 10.5 moles
b. 5.00 moles
c. 6.5 moles
d. 5.4 moles
Answer:
d) n = 5.4 mol
Explanation:
Given data:
Number of moles of He = ?
Volume of He gas = 120 L
Temperature and pressure = standard
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × 120 L = n × 0.0821 atm.L/ mol.K × 273.15 K
120 atm.L = n × 22.43 atm.L/ mol
n = 120 atm.L / 22.43 atm.L/ mol
n = 5.4 mol

Examine why amusement park rides have
restraint bars to keep people safe. Apply
Newton's first law of motion to your
explanation.
Answer:
Newton's first law of motion states that an object in motion tends to stay in motion. This is what keeps the roller coaster rolling through the hills and turns after it accelerates down the initial ramp. Also, the riders inside the car will experience changes in accleration and apparent weight. The riders will keep going at the same speed in the same direction unless some other force (the seat) acts on them to change that speed or direction. At the bottom of hills, they try to continue downward, and are pressed into the seat. At the tops, the riders are lifted up in their seats as they try to continue upward even as the seat pulls them down into the next drop. The same thing occurs on turns, where riders are pushed into the side of the seat as the coaster turns. (This is the reason for harnesses, seat belts, and restraining bars.)
Explanation:
The chance of getting out moved from the seats is more in riders or on vehicles because, as stated by the first law of motion an object tends to stay in its state unless an external force acts on it. Thus, the ride will tend to move front even after stopped.
What is inertia?Inertia is the tendency an object to continue its state of motion or rest until an external force act on it. This concept is explained by Newton's first law of motion.
This effect can be in many situations. For example in moving bus, when it is suddenly breaked, the travelers will move up front just because of the inertia of the bus. Similarly a stationary bus, when started will initially move back once.
The riders in amusement park will experience the same. Hence, there is a possibility of people moving out from the seat when it is stopping or starting that's why they have restraint bars.

A compound contains oxygen and chlorine. Its molecular mass is 166.9g. What is the molecular formula if its empirical formula is CIO3?
The molecular formula : Cl₂O₆
Further explanationGiven
Molecular mass = 166.9 g
The empirical formula = ClO₃

The molecular formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
(ClO₃)n=166.9
(35.5+3.16)n=166.9
(83.5)n=166.9
n=2

An atom with one electron in its valence
shell will tend to:
An atom with one electron in its valence shell will tend to lose that electron to achieve the noble gas configuration and becomes a cation.
What is a cation?Cations are positively charged ions and are formed when an atom loses its electrons. They lose one or more electrons from their valence shell but do not lose any protons. Therefore, they get a net positive charge. Some examples of cations are Potassium (K⁺), Calcium (Ca²⁺), and hydrogen (H⁺).
Anions and cations are both ions and have opposite electrical charges. They feel attraction for each other. A cation repels another cation whereas an anion repels another anion.
An atom that has one electron in its valence shell will always tend to lose that electron to get completely filled electronic configuration. So the atom will convert into a cation to attain the more stable noble gas configuration.
For example, sodium has an electronic configuration 1s²2s²2p⁶3s¹. It has one electron in its valence shell, so it converts into Na⁺ by losing one electron and attains a configuration similar to Neon noble gas.

mass of Neon
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
so mass of Neon(MM=20,1797 g/mol) :
= mol x MM
