Chemical Equation Basics
Chemical Equation Basics Teacherflix 3 Views • 2 years ago

What does a chemical equation tell you?
A chemical equation is the written expression of a chemical reaction.Welcome to MooMooMath and Science
In this video I would like to talk about chemical equations.
Chemical reactions occur all around us.
They can be exciting like these fireworks, also helpful like these fires..
A chemical reaction can be represented using a chemical equation.
Let's breakdown this chemical equation and see what information it contains.
First,the reactants are on the left of the arrow and products are on the right of the arrow
This equation has methane which is ch4 combining with oxygen which is O2
The plus marks on the left of the arrow tells which elements or compounds are combining
The arrow tells you what it will produce or yield. The right side of the arrow are your products or what is produced
The products in this equation are co2 which is carbon dioxide and h2o or water.
Each capital letter represents a new element and each element has a symbol. The symbol for every element can be found on the periodic table.
A number behind a letter tells is a subscript and represents how many ions of the element are in the chemical equation
H20 tells you that the compound has two hydrogens and 1 oxygen
What do the numbers in front of a letter tell you?
Coefficients are the numbers in front of the formulas
the coefficients give the number of moles of each substance involved in the reaction. In the example reaction 2 H2 + O2 yields 2 H2O
two moles of hydrogen react with one mole of oxygen and produce two moles of water.
Atoms are neither created nor destroyed.
In other words it must be balanced.
If you count the atoms with this reaction you will notice that it is not balanced.
This new equation is balanced because you have equal numbers of elements on both sides.
I will leave a note in the show notes for a video I created on balancing equations.
You can also indicate the physical states of the reactants and products
Here are some symbols
S = solid
l = liquid
g = gas
and aq = dissolved in water
In this chemical equation you have a solid plus a liquid and it produces a hydrogen gas dissolved in water.
So there you go
chemical equations
Reactants on the left, products on the right

In this video, I would like to show some examples of diffusion.
Diffusion is when objects move from an area of high concentration to an area of low concentration.
Check out this example, of diffusion.
You can another simple example of diffusion when you watch the food coloring diffuse into the water.
If you take an egg and soak it in vinegar and then place it in water, the water will diffuse into the egg causing it to get larger.
If you place sugar into coffee it will diffuse out into the coffee.
Watering plants diffuses the water into the plants
When you go into Starbucks and smell the coffee smell the smell of the coffee has diffused through out the coffee shop.
You can soak a gummy bear in water and the water will diffuse into the gummy bear. and it will get larger.
Those are several examples of diffusion.
When objects move from high concentration to low concentration.
Thanks for watching and MooMooMath and Science uploads a new Math and Science video everyday.

Boiling point and Melting point-Physical Properties
Boiling point and Melting point-Physical Properties Teacherflix 3 Views • 2 years ago

Boiling point and Melting point--

The boiling point is the temperature at which a substance changes from a liquid into a gas.
The boiling point varies for different substances and can be used to help identify elements of the periodic table and other substances. For example, water and rubbing alcohol look similar but water has a boiling point of 212 f and 100 c and rubbing alcohol has a boiling point of 180.7 f and 82.6 c
The element found on the periodic table with the lowest boiling point is helium at -452.1 f and -269c
Tungsten has the highest boiling point at 10,030 f which is 5660 c

Boiling point varies with your elevation. It is higher at sea level and decreases as you gain elevation. As a result,

The standard boiling point has been defined by IUPAC since 1982 as the temperature at which boiling occurs under a pressure of 1 bar which is a fancy way of saying the standard boiling point is the boiling point at sea level

The melting point is the temperature at which a substance changes from a solid to a liquid.
This snow melting is an example of the water reaching it’s boiling point.
The melting point is also impacted by atmospheric pressure which changes with elevation but not as boiling point does.
The melting point is a physical property and can be used to identify substances.
The melting point of water is 32 f and 0 c
Helium has the lowest melting point at -272 c and carbon has the highest at 3500 c
Compare this to steel which has a melting point of 1510 degrees c

There are four main classifications of galaxies

Elliptical galaxies which are featureless and spiracle.

Spiral these have arms that spiral outward


Lenticular galaxies are given the symbol S0. These galaxies consist of a bright central bulge, similar in appearance to an elliptical galaxy, surrounded by an extended, disk-like structure.

Irregular galaxies are any other galaxy

What happens in prophase?
Cell Division Crossword Puzzle
http://www.moomoomath.com/cell....-division-crossword-

Prophase is the first stage of mitosis.
During prophase, the chromosomes first begin to appear.
Next, the nuclear membrane begins to break down, and the centrioles produce mitotic spindle fibers.
