How To: Follow three rules to balance chemical equations

In this video, we learn how to follow three rules to balance chemical equations. The first rule is that you need to start by balancing elements that appear in only one reactant and one product. The second rule is that you need to multiply through by common factors. You must retain equal numbers of atoms of each element on both sides of the equation. The third rule is: if an atom appear in elemental form on one side of the equation, save it for last. Going over the rules of how the balance the...

How To: Understand chemistry & chemical change

This video tutorial is in the Education category which will show you how to understand chemistry and chemical change. The question here is 10g of Mg ribbon reacts with 0.15 mol decimeter cubed of hydrochloric acid at 25 degree Celsius. What is the balanced equation for this reaction? When magnesium reacts with hydrochloric acid, you will get magnesium chloride and hydrogen. So, the equation will be Mg + 2HCl = MgCl2 + H2. Mg is in group 2 of periodic table and has a valance of 2, whereas Cl i...

How To: Find percent by mass & percent composition

In chemistry you come across problems which ask you to find the percent by mass and percent composition of each element in a chemical compound. To do this the first step is to compute the molar mass. Use the periodic table to look up the mass of individual atoms and multiply it by the number of atoms to find the mass of that element. Now add up all the masses to arrive at the molar mass of the compound. Now to find the percent composition of an element divide the total mass of each element by...

How To: Balance a chemical equation with ease

Learn how to balance the three different types of chemical equations in simple steps. First take an equation, write down its reactants and products and write down the names of all elements. Now write down how many of each element are present in the equation. Now check which element does not match, in this case the Oxygen doesn't match. Now multiply the element or compound starting at two but now hydrogen doesn't match. Try to match them by multiplying the coefficients but now sulfur doesn't m...
