A cylinder at left with balls evenly spaced throughout the cylinder with an arrow leading to a cylinder at right with balls stacked near the bottom of the cylinder.
Which change of state is shown in the model?
condensation
deposition
boiling
freezing
Answer:
deposition
Explanation:
The model above shows a transition from a gas state to a solid state. This is known as "deposition."
The particles are widely-spaced on the left because they have a lot of energy; thus, they don't interact with each other. This is the reason why the gas doesn't have a definite shape and volume.
The particles on the right are stacked near the bottom because they don't have enough energy to move about; thus they interact with each other. This gives solid a definite shape and a definite volume. They can only move if the thermal energy increases.

How does the atomic radius increase?
Answer:
increases as you move down a group as the number of electrons increases. Therefore, the atomic radius increases as the group and energy levels increase
Explanation:
Question The compounds 2-butanol and 2-butene both contain (1) double bonds, only (3) carbon atoms (2) single bonds, only (4) oxygen atoms Answer · 6 votes The answer is (3) carbon atoms. For 2-butanol, it contains single bonds only and with C, O, ... Mor
Answer:
carbon atoms
Explanation:
Let us look at the molecular formulas of each compound;
Butanol= C4H10O
Butene= C4H8
We can clearly see that the both compounds contains four carbon atoms each. Hence the correct answer is that the both compounds contain the same number of carbon atoms
What determines the number of hydrogens in an acid?
Answer:
It's the same as the charge of the anion
Explanation:
What determines the number of hydrogens in an acid is the charge of the corresponding anion. This is otherwise termed the Basicity of the acid
According to the question;
We are required to identify what determines the number of hydrogens in an acid.An acid is typically made up of an Hydrogen ion(Cation) and another anion.
For instance:
HCl is made up of 1 H+ ion and 1 Cl- ion.While, H2SO4 is made up of 2 H+ and one SO4²- ion.Read more:

How many moles of oxygen are required for the combustion of 35.5 g of Magnesium Mg+O2-->MgO Please balance
Answer:
0.74 moles of oxygen are required for combustion
Explanation:
Given data:
Number of moles of oxygen required = ?
Mass of Mg = 35.5 g
Solution:
Chemical equation:
2Mg + O₂ → 2MgO
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 35.5 g/ 24 g/mol
Number of moles = 1.48 mol
Now we will compare the moles of Mg with oxygen.
Mg : O₂
2 : 1
1.48 : 1/2×1.48 = 0.74 mol
0.74 moles of oxygen are required for combustion.

How many moles of salt do you have, if you have 5.00 x 10^26 formula units of salt?
Answer:
830.56 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L}\\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{5.00 \times {10}^{26} }{6.02 \times {10}^{23} } \\ = 830.5647..[/tex]
We have the final answer as
830.56 molesHope this helps you

What is the significance of the Schrödinger wave equation to the quantum mechanical model of
the atom?
Answer:
Quantum Mechanical Model of Atom
The solution of the wave equation brings the idea of shells, sub-shells and orbitals. The probability of finding an electron at a point within an atom is proportional to the |ψ|2 at that point, where ψ represents the wave-function of that electron.

Answer: .03 M
Explanation:
you have to use m1v1 = m2v2
but the units should be in L so we need to convert the 32.20 and 26.60 into L by dividing them by 1000. So now we have .0322 and .2660
.0322(.25)=(.2660)(x)
x = .03
What is the atomic mass of bromine, given the atomic masses and percent abundance of the two isotopes are 78.92 amu (50.7%) and 80.92 amu (49.3%)?
Select one:
a. 79.9 amu
b. 78.9 amu
c. 80.9 amu
d. 35 amu
Answer:
79.9 amu
Explanation:
Given data:
Atomic mass of bromine = ?
Percent abundance of 1st isotope = 50.7%
Atomic mass of 1st isotope = 78.92 amu
Percent abundance of 2nd isotope = 49.3%
Atomic mass of 2nd isotope =80.92 amu
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (50.7×78.92)+(49.3×80.92) /100
Average atomic mass = 4001.24 + 3989.36 / 100
Average atomic mass = 7990.6 / 100
Average atomic mass = 79.9 amu.

Answer: 1 . Unsaturated Solution
2. Saturated Solution
Explanation:
1 ..tedsaturauntionsolu----------- Unsaturated Solution
2. ratedsatulutisoon--------------Saturated Solution
An Unsaturated solution is defined as a solution which contains an amount of solute that dissolves completely since the amount of solute is still less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.
example include. Addition of salt or sugar in water and it dissoves completely.
A saturated solution is defined as A solution which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.
Example- The addition of sugar to water till it no longer dissolves
Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles it gives offf in form of carbon.
