Answer:
The ranking of matter from the LEAST amount of energy to MOST amount of energy is;
B. Solid, Liquid, Gas
Explanation:
The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating
Solid state (Least amount of energy)
In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer
Liquid state (Intermediate amount of energy)
As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state
Upon further heating the particles in the liquid acquire more energy and are and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form
Gaseous state (Most amount of energy)
From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed
Therefore, the correct option is Solid, Liquid, Gas.

gas > liquid > solid

Plot a graph of relative atomic mass against boiling point for the
elements in Group 0.
Answer:
I found this, hope it works
Explanation:
As the mass of the noble elements increases the boiling point gradually decreases and the graph of the two parameters is a straight line graph with downward slope.
What is an element?It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

how do you find out which molecule out of two is more polar
Answer:
Check the electronegativities of the atoms involved in each bond. The greatest difference in electronegativity will correspond to the most polar bond.
How many moles are in 43.5 g of sodium hydroxide (NaOH)?
Answer:
1.09 moles of NaOH
Explanation:
First of all, to calculate moles, you need to find the molar mass of NaOH.
Let us first find the molar mass of NaOH then.
Na = 23.0 amu
O = 16.0
H = 1.0
They are 1 nitrogen atom, 1 oxygen atom, and one hydrogen atom.
So do this.
23.0(1) + 16.0(1) + 1.0(1) = 40 g/mol.
Now use dimensional analysis to show your work
43.5 g of NaOH * 1 mol of NaOH / 40 g/mol of NaOH
The grams cancel out.
43.5 / 40.0 = 1.0875
Use sig figs and round the answer to the nearest hundredths place.
1.0875 = 1.09
So the final answer is 1.09 moles of NaOH

How many atoms of oxygen are in 566 g of glucose? * How many molecules are there in 43 grams of sodium hydroxide? * How many atoms of fluorine are in 5.5 x 10^24 molecules of sulfur hexafluoride? *
Answer:
See explanation
Explanation:
Number of moles of glucose in 566g = 566g/180g/mol = 3.14 moles
Number of moles of oxygen atoms in 1 mole of glucose= 6 * 16g/16g/mol = 6 moles.
There are 6 moles of oxygen in 1 mole of glucose
x moles of oxygen is therefore present in 3.14 moles of glucose
x = 6 * 3.14/ 1 = 18.84 moles of oxygen
1 mole of oxygen contains 6.02 * 10^23 atoms of oxygen
18.84 moles of oxygen contains 18.84 * 6.02 * 10^23 atoms = 1.14 * 10^25 atoms of oxygen.
Number of moles of sodium hydroxide in 43g of NaOH = 43g/40g/mol = 1.075 moles
1 mole of NaOH contains 6.02 * 10^23 molecules of NaOH
1.075 moles of NaOH contains 1.075 moles * 6.02 * 10^23 molecules / 1 mole of NaOH = 6.47 * 10^23 molecules of NaOH
Number of moles of atoms fluorine in SF6 = 6 * 19 g/19 g/mol = 6 mole of F atoms
1 mole of SF6 contains 6.02 * 10^23 molecules of SF6
x moles of SF6 contains 5.5 x 10^24 molecules of SF6
X = 5.5 x 10^24 molecules * 1/ 6.02 * 10^23 molecules
X = 9 moles of SF6
If 1 mole of SF6 contains 6 atoms of F
9 moles of SF6 will contain 9 * 6/1 = 54 atoms of F
23) What is the volume of 2.454 x 1024 atoms of nitrogen gas at STP?

[b] 6.595 x 1048 L
[c] 2.241 x 1026 L
[d] 91.31L
Answer:
d) V = 91.3 L
Explanation:
Given data:
Volume of nitrogen = ?
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Number of atoms of nitrogen = 2.454×10²⁴ atoms
Solution:
First of all we will calculate the number of moles of nitrogen by using Avogadro number.
1 mole = 6.022×10²³ atoms
2.454×10²⁴ atoms × 1 mol / 6.022×10²³ atoms
0.407×10¹ mol
4.07 mol
Volume of nitrogen:
PV = nRT
1 atm × V = 4.07 mol ×0.0821 atm.L /mol.K ×273.15 K
V = 91.3 atm.L /1 atm
V = 91.3 L

how many moles are represented by 3.01x10^23 helium atoms
a. 1 mole
b. 0.50 moles
c. 0.75 moles
d. 5 moles
Answer:
b. 0.50 moles
Explanation:
To solve this problem we use Avogadro's number (6.023x10²³ atoms/mol).
By dividing the number of atoms (or molecules) by that number, we can calculate how many moles they represent.
3.01x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.50 molesSo the answer is option b. 0.50 moles.

Applying a force for a longer time increases the change in
(select all that apply)
Weight
Gravity
Velocity
Mass
Momentum
Answer:
velocity and momentum
Explanation:
as you exert force, the object accelerates, hence, its velocity increases.
since momentum is mass times velocity, the momentum increases too
Please be reminded, this answer may not be 100% correct
When the force should be applied for a long time so it increases the change in velocity and momentum
What is velocity and momentum?The momentum of the object should be equivalent to the object mass times with the object velocity
Here
p = mv
Here p means momentum
m means mass
v means velocity
Here the momentum should be directly proportional to the mass of the object and for the velocity of the object also.

1) A chemist was deciding what chemical to use in a handwarmer. She studies 2 compounds. One is a nonpolar covalent compound that is safe and nontoxic. The other is an ionic compound. It is poisonous if ingested. What tests could she do to tell them apart? Give two possible observations or tests she can run to verify the substance. Which substance would you use to make the handwarmer and why?
Answer: Water dissolves nonpolar covalent substances.
The Nonpolar substance which is nontoxic is better material to be used in making the hand warmers.
A hand warmer is a little substance which can be put in between the hands in order to heat them up. This is particularly of necessity in the cold weather when the hands are cold.
The chemist can distinguish the polar substance from the nonpolar substance by dissolving each substance in water. The polar substance will dissolve in water while the non polar substance will not dissolve in water.
Secondly, the two substances can be heated and the melting temperatures are observed. The ionic substance will melt at a much higher temperature than the nonpolar substance. The Nonpolar substance which is nontoxic is a better material to be used in making the hand warmers.
