Your metabolism is the sum of all chemical reactions in your body.

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 math lesson, you will learn how to tell time on an analog clock. In this lesson, we will focus on reading the short or hour hand and the long minute hand.
We will learn three easy steps to tell time.
Start at the small hand
Write two dots
Read the large hand.

Learn how to solve problems involving Boyle's law. Boyle's law states that as pressure increases then volume decreases and pressure decreases volume increases.
I use the Boyle's law formula Pressure x Volume = K
Example problem:
3.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure?

A gas occupies 12.3 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg?

What are the factors that allow the Earth to sustain life?
Life has been around for a long time. How does the earth help life on earth keep going and going and going.
I would like to look at three processes and one force that work together to help sustain life.
First, life is sustained by the flow of energy from the sun through the biosphere.
The biosphere is any location on earth that has life.
Plants contain chloroplasts which have the ability to convert sunlight into sugar.
Plants combine carbon dioxide, water and sunlight into glucose.
Animals eat plants and the energy from the sun is transferred to the animal.
Other animals eat these animals and the energy from the sun is spread throughout the ecosystem
The next process is the cycling of nutrients within the biosphere.
The earth has several biochemical cycles that recycle important chemicals
These cycles move chemical substance from the biotic and abiotic compartments of Earth. There are biogeochemical cycles for carbon, oxygen, nitrogen, phosphorus, sulfur, and water;
These cycles keep recycling these important chemicals so that we don’t run out of these chemicals.
Life has the ability to duplicate itself. It can be the offspring of two adults or bacteria that uses binary fission to rapidly make copies of itself.
Finally, gravity is the force of attraction between objects.
Gravity hold life on earth and also holds our atmosphere close to the earth.
The atmosphere contains important gases like oxygen which are essential to life.
Without gravity, the earth would not have an atmosphere and life as we know it would go away.
So there you go,
How life keeps going and going and going
