This organic chemistry video tutorial discusses shielding and deshielding as it relates to H-NMR spectroscopy. A hydrogen nucleus is said to be shielded from an external magnetic field if it is an electron rich environment. It will thus appear upfield in the NMR spectrum. Protons adjacent to electron withdrawing group are said to be deshielded and appear downfield in a NMR spectrum.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Animal adaptations for kids is a video that explores the different ways that animals can adapt to their environments. There is a number of ways that different animals do this, from Migration or Hibernation, to Body Structures and even changing their colors and in this video we will explore them all. There are different kind of animal adaptions Behavioral Adaptions, Physical Adaptions, and Life Cycle Adaptions each animal might use a different technique but ultimately they are adapting to survive in their environment.

After viewing this video we invite you to download and go through our free Animal Adaptations lesson plan with more activities, learning content, worksheets and more! When completed your students will be able to identify and describe various
animal adaptations used for survival in the environment.

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
