How to Do Stoichiometry
In a chemical reaction, matter can neither be created nor destroyed according to the law of conservation of mass, so the products that come out of a reaction must equal the reactants that go into a reaction. This means the same amount of each atom that you put in must come back out. Stoichiometry is the measure of the elements within a reaction. It involves calculations that take into

How to Purchase Liquid Nitrogen
People use liquid nitrogen (LN2) for a variety of purposes, including freezing warts, performing science experiments, welding metals, preserving biochemical materials, and even home cooking. Yet since it’s potentially hazardous, you can’t just pick it up at the grocery store like you would a gallon of milk. By researching where to find a supplier, what container to get, and how to fill

How to Find Valence Electrons
In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element. Knowing how to find the number of valence electrons in a particular atom is an important skill for chemists because this information determines the kinds of chemical bonds that it can form and, therefore, the element's reactivity. Luckily, all you need to find an element's

How to Formulate White Phenyle
White phenyle (sometimes written as phenyl) is a disinfecting agent made from pine oil. It is made by using an emulsifier- a compound that allows an oil to stably make a solution with water. Without the addition of an emulsifier, the oil and water would continuously separate if the solution sits for too long. White phenyle is used as a cleaning product to remove odors and kill bacteria.

How to Calculate Anion Gap
The body naturally strives for balance and equilibrium. When extra H ions or acids are released, the body suffers from a condition referred to as metabolic acidosis. This increases the respiratory rate and decreases your plasma levels. Anion gap is used to determine the exact reason of this condition. It determines unmeasured anions which are the phosphates, sulfates, and proteins in

How to Calculate pH
In everyday life, pH is a scale generally used to describe the neutrality, or lack of neutrality, in a household item. In science, pH is a measure of ions within a solution. If you’re taking a science or chemistry class, you may need to know how to calculate pH based off concentration instead. Calculate pH by using the pH equation: pH = -log10[H3O].

How to Study the Chemistry of Explosives
From firecrackers to nuclear bombs, explosives have the ability to excite and terrify people. The first known use of explosives is credited to the Chinese who used them in celebrations. Later one they were adapted for use in wars, mining industries, construction and demolition, and countless other applications. In each case, you need the right explosive for the job or you will be

How to Collect Hydrogen
Hydrogen is the lightest element and has many industrial uses, including the creation of hydrogenated fats for use in the kitchen and the production of hydrocarbons from coal. It is an essential part of water molecules and can be separated out using a small amount of electricity. You can also produce hydrogen gas using some active metals and strong acids. Both methods are relatively

How to Buy Citric Acid
Citric acid is available for purchase through many different types of stores. Where you choose to buy citric acid depends on what you plan to use it for and how much you wish to purchase. Citric acid is a weak acid naturally found in citrus fruits that individuals and manufacturers often use because of its preservative and chelating properties and sour taste. Citric acid is important
