Describe how the particle motion is different from state to state.
Answer:
The particles in a gas are moving very quickly in random directions.
The particles in a solid are tightly packed and locked in place, and they are vibrating in their place.

the number of protons will tell you what elements it is. T or F plzz help
Answer:
True
Explanation:
There are two ways to tell elements apart from each other: the atomic number or the number of protons. The atomic number tells the number of protons in the element.
For example:
There are two given elements. One has 3 protons and an atomic number of 3 while the other has 7 protons and an atomic number of 7. Which one is Lithium?
Lithium has an atomic number of 3, which means it has three protons, which means Lithium is the one with 3 protons.

What mass of ethanol will All
a 250.0 ml container if its
density is 0.789 g/ml?
Answer:
The answer is 197.25 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 250 mL
density = 0.789 g/ml
So we have
mass = 250 × 0.789
We have the final answer as
197.25 gHope this helps you
Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R
Answer:
Unit of resistance is Ω (Omega).
Explanation:
The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :
V = IR
R is resistance
Its unit is Omega and it is represented by Ω.
The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer
What is resistance?Resistance is simply the measure of the opposition to current flow in an electrical circuit.
Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.
V = I × R
Where;
V is the voltage or potential difference. I is the current.R is the resistance.The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps
The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂
Further explanationEqualization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc. 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product 3. Select the coefficient of the substance with the most complex chemical formula equal to 1Reaction
[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]
1. Coefficient
KClO₃ ⟶ aKCl + bO₂
2. Equation
K ⇒ left =1, right=a ⇒a=1
Cl⇒ left =1, right=a ⇒a=1
O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5
The equation turns into :
KClO₃ ⟶ KCl + 1.5O₂
multiplied by 2
2KClO₃ ⟶ 2KCl + 3O₂
organize the following elements in order of increasing atomic radius (Ge, He, Sr, O, Ba)
Answer:
He
O
Ge
Sr
Ba
Explanation:
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.
In general, the size of an atom will decrease as you move from left to the right of a certain period.
K+ Cl2 → КСІ balance equation
Which of the following is NOT a characteristic of a compound?
A. has different properties from the elements that formed it
B. pure substance made of two or more elements
C. can be represented by a chemical formula
D. different samples have different properties
Answer:
I think it's D
sorry if I'm wrong.
Explanation:
Options that are not characteristics of compound in the question is D. different samples have different properties.
A compound can be regarded as a substance which is formed by chemical combination of two or more elements.Examples of compound are water ( H2O), Sodium chloride ( NaCl)Some of the properties of a compound are;
A compound will always has a different properties which is different from the properties of each of the elements making up the compound.A compound are formed as a result of two or more elements that combined chemically.A compound can be identified with its chemical formula.Therefore, option D is correct because a compound will only has its own properties not that
