Balancing Equations in El Segundo

El Segundo High School students that need chemistry tutoring are in luck. Study Hut tutoring in El Segundo is going to get you going where you want to go. We are experts in every subject, with tutors who’s knowledge is and teaching style is tailored to each of the students who come in for subject help and test prep. Take a look at this breakdown from Andy, our UCLA bio/chem major who dominates science like nobodies business (but ours!):

Sometimes balancing chemical equations is easy….unfortunately it can also be
a nightmare! When all else fails there is one way to balance an equation that will
always work; with ALGEBRA! Who ever said learning math wasn’t useful?

To solve balance chemical equations using algebra start by assigning a variable
to each part of the reaction. For example if we had the unbalanced equation

NaHCO2 + C6H8O7 ——-> CO2 + H2O + Na3C6H5O7

First we assign a value of 1 as the coefficient of the first compound. We then give
letter designations to the other coefficients.

(1)NaHCO2 + (A)C6H8O7 ——-> (B)CO2 + (C)H2O + (D)Na3C6H5O7

Now we can establish relationships between the variables based on the different
atoms.

Sodium: 1=3D
Hydrogen: 1 + 8A = 2C + 5D
Carbon: 1 + 6A= B + 6D
Oxygen: 2 + 7A = 2B + C + 7D

Now we solve these equations starting with Sodium

1=3D ——–> D=1/3

We then plug D=1/3 into the Hydrogen and Oxygen equations and solve for C
and B respectively:

1 + 8A = 2C + 5D ———> C = 4A – 1/3

1 + 6A = B + 6D ———–> B = 6A -1

Finally if we put these into the Oxygen equation we can solve for A:

2 + 7A = 2B + C + 7D ———–> 2 + 7A = 2(6A-1) + (4A-1/3) + 7(1/3)

This give A = 2/9. Now we can go back to Hydrogen and Oxygen and solve for C
and D.

C = 4A – 1/3 —–> 4(2/9) – 1/3 = C
C = 5/9
B = 6A -1 ——–> 6(2/9) -1 = B
B= 3/9

This give us: (1)NaHCO2 + (2/9)C6H8O7 ——-> (3/9)CO2 + (5/9)H2O + (1/3)

Na3C6H5O7

To get whole numbers we multiply by 9 giving us the solution!

(9)NaHCO2 + (2)C6H8O7 ——-> (3)CO2 + (5)H2O + (3)Na3C6H5O7

This method may seem complex, but it is guaranteed to work for any chemical
equation!

The new tutor experience

I’ve only been a tutor at Study Hut for two weeks, but I am most impressed with my students who are well-organized. What does a well-organized student do? They fill out their agendas with all their homework and upcoming tests/quizzes. They fully take advantage of their planners. They bring in all their books and homework worksheets to the tutoring session (those that do not have the correct materials, just end up wasting time by having to call someone to bring the book or having the tutor waste time figuring what the student has to do). The well-organized students are able to get more from their tutoring session because they have a plan for what to do before they even show up to study hut. They know what classes they have homework in and are able to assess their weakest subjects so that we can spend the session working on that subject.

One of my most organized students is Tim, a junior, from Mira Costa High. Tim mainly comes for help in Geometry and Chemistry. While he may not know how to do the problems at first glance, after an explanation of the concept behind the problems, he is able to work out similar problems by himself. One of the main reasons why Tim is able to do this is because he writes down all his work on paper. I constantly stress to my students to show all their work because if they get the wrong answer, they can go back and pinpoint exactly where they made a mistake. This enables the student to make a mental note of the mistake they made and not make it again in the future. Tim also comes to each session with an attack plan on what to do during the session and he always knows whether he has an upcoming quiz or test.

In all, to stay ahead of the game that is school, one needs to be organized by making full use of the planner and to show all relevant work when doing homework!

Making Learning Fun!

Today’s students are expected to have a much more comprehensive understanding of their subject matter, especially in mathematics and science.

It’s not enough to know what the components of DNA are anymore. High school Biology students are expected to how the different building blocks fit together and why. For a lot of students, the sheer volume of information flying at them daily is more than overwhelming.

Study Hut helps students navigate these murky waters by providing the kind of thorough and interactive support that allows students to take control of their own learning.

“Give a man fish, and you’ll feed him for a day. Teach a man to fish, and you’ll feed him for a lifetime.” ~ Chinese Proverb

More than just providing what students need from day to day, our tutors teach their students both the skills to be self-sufficient and the confidence essential to managing those unavoidable high-stress situations.

We also help them develop study techniques that take advantage of their already sizeable knowledge base and learning strengths.
