How To Balance Equations - Part 2 | Chemical Calculations | Chemistry | FuseSchool

Continue learning about balancing equations, as a part of chemical calculations.
The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms.
Chemical reactions can be represented by symbol equations so long as the number of atoms on each side of the equals sign remains the same. Equations need to be balanced to conserve atoms, by putting numbers in front. A good way to balance an equation is to use a table to keep track of everything.
You can only change the big number in front of the compounds, which says how many molecules you have.
Charges in a formula also need to be balanced.
So, both the atoms and the charges have to balance. Nothing can appear or disappear! This is the most important rule about balancing: no atoms or charges can be made or destroyed.

In this video we’re going to look at how to simplify algebraic expressions. Before we get started on simplifying, a few things to remember:
(1) we always use a use a curly x for the letter x in algebra.
(2) We don’t really use the mul

In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
