What are different states of matter?The matter is anything that has mass and occupies space.
Matter can exist in four different states: solid, liquid, gas, and plasma.
By examining the arrangement of molecules, it is possible to comprehend the characteristics of the many forms of matter.
The state of a solid turns to a liquid when it is heated past its melting point.
A liquid turns into a gas when it is heated past the point at which it vaporizes.
Solids have a distinct shape and dimension and are densely packed.
Liquids fill the container's space and are loosely packed.
Gas has a large intermolecular distance and is not stiff.
When energy is removed from the particles of a liquid, the speed gets slowed, and so the motion decreases, as the motion is limited they become packed and the distance between them decreases, and the intermolecular forces increases.

What do eukaryotic cells, prokaryotic cells and viruses all have in common?
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Once upon a time, Walter the water molecule was traveling around Linda's blood. He was enjoying moving around wherever he wanted. One day, Walter decided to visit some cells. He traveled in and out of the cells as he pleased. Walter decided that he liked the cells so much that he wanted to stay inside and rest in the vacuole. However, as the day went on, Walter felt a change happening around him. Linda had eaten some VERY salty popcorn. Walter LOVED Sally the salt molecule and felt a magnetic attraction to her. The closer the salt came to the cell, the quicker Walter's love for Sally pulled him out of the cell and towards the salt.
Answer:
This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.
Explanation:
The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.
For this to happen, a highly water-permeable barrier is needed.
What would happen to the rate of a reaction if the concentration of substrate was increased after the point of saturation?
a)The reaction rate would increase.
b)The reaction rate would decrease.
c)There would be no effect.
Answer:
there would be no effect
Explanation:
Identify the reactants and products, and describe the change in energy that occurs as bonds are broken and formed.
Answer:
Chemical reactions almost always have a change in energy between products and reactants. The total energy of a system must remain the same and sometimes a chemical reaction will absorb or release energy as light, heat or both. The energy change in a chemical reaction is caused by the amount of stored energy between the products and the reactants.

Calculate the molarity of a NaOH solution that is prepared by diluting 100mL of 0.20M NaOH with 150mL of H2O.
Molarity of solution = 0.08 M
Further explanationMolarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
[tex]\tt M=\dfrac{n}{V}[/tex]
Where
M = Molarity
n = number of moles of solute
V = Volume of solution
mol of NaOH[tex]\tt mol=0.2~M\times 100~ml=20~mlmol=0.02~mol[/tex]

Write a complete, balanced chemical equation where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas. Include states.
From the equation, which element is oxidized, and which element is reduced?
Answer:
1. The balanced equation is given below:
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
2a. H is oxidized.
2b. Sn is reduced.
Explanation:
1. Balanced equation for the reaction between tin (Sn) metal and aqueous hydrochloric acid (HCl) to produce tin(II) chloride (SnCl₂) and hydrogen gas (H₂).
This is illustrated below:
Sn (s) + HCl (aq) –> SnCl₂ (aq) + H₂ (g)
There are 2 atoms of Cl on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
Now, the equation is balanced
2. Determination of the element that is oxidize and reduced.
This can be obtained as follow:
We shall determine the change in oxidation number of each element.
NOTE:
a. The oxidation number of H is always +1 except in hydrides where it is –1.
b. The oxidation state of Cl is always –1.
Sn (s) + 2HCl (aq) –> SnCl₂ (aq) + H₂ (g)
For Tin (Sn):
Sn = 0
SnCl₂ = 0
Sn + 2Cl = 0
Cl = – 1
Sn + 2(–1) = 0
Sn – 2 = 0
Collect like terms
Sn = 0 + 2
Sn = +2
Therefore, the oxidation number of Tin (Sn) changes from 0 to +2
For H:
H = +1
H₂ = 0
The oxidation number of H changes from +1 to 0
For Cl:
Cl is always –1. Therefore no change.
Summary:
Element >>Change in oxidation number
Sn >>>>>>>From 0 to +2
H >>>>>>>>From +1 to 0
Cl >>>>>>>No change
Therefore,
Sn is reduced since its oxidation number increased from 0 to +2.
H is oxidized since it oxidation number reduced from +1 to 0
The balanced chemical equation for the reaction is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H)
The balanced chemical equation for the reaction where tin metal reacts with aqueous hydrochloric acid to produce tin(II) chloride and hydrogen gas is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
From the equation,
The element that is oxidized is tin (Sn), because the oxidation state of Sn increased from 0 to +2
The element that is reduced is hydrogen (H), because the oxidation state of H decreased from +1 to 0.
Hence,
The balanced chemical equation for the reaction is
Sn(s) + 2HCl(aq) → SnCl₂(aq) + H₂(g)
and the element that oxidized is tin (Sn) while the element that is reduced is hydrogen (H).

what is the standard form of 12,341 us?
Answer:
12341 in standard form = 1.2341 × 10⁴
Explanation:
When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.
As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.
As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:
12341 in scientific notation = 1.2341 × 10⁴.
This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.

A student drops a 95g object into a graduated cylindor that has 30ml of water in it. After the object is added to the cylinder the water level reads 63ml. What is the density of the object?
Answer:
The answer is 2.88 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 95g
volume = final volume of water - initial volume of water
volume = 63 - 30 = 33 mL
We have
[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]
