How To: Use & understand chemical equilibrium in chemistry

This is a video tutorial in the Education category where you are going to learn how to use and understand chemical equilibrium in Chemistry. This video answers a question about the contact process. This is a process by which sulphuric acid is made where they take sulphur, react it with oxygen to make sulphur dioxide and react it with more oxygen to make sulphur trioxide. The equation here is 2SO2 + O2 will give us 2SO3. This reaction is exothermic, that means it will give out energy in the fo...

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...

News: Scientists Turn Bacteria into Mini Cyborg Solar Panels

Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
