Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

Observations of Chemical Changes Purpose/Hypothesis: To observe how acids react with bases and examine reactions of common household cleaners and the macroscopic changes these chemicals undergo. I expect for each solution to react differently when mixed with acids and bases. Procedure: I have a well-plate-96‚ a piece of white and black paper‚ and the chemicals from the Observation of Chemical Changes Experiment Bag. I used a different well for each combination of solutions. I placed two

Chemical equilibrium is a state of balance within a system of chemical reactions. Equilibrium in chemistry is achieved when substances are produced and broken down at the same rate and thus‚ the number of molecules of each substances becomes constant. Thermodynamics is a branch of physical science that involves the relationship between heat and other forms of energy (Energy‚ Enthalpy‚ and the First Law of Thermodynamics). There is a more specific area of thermodynamics that explicitly pertains to

However‚ this time‚ instead of being struck by a bomb‚ they were struck by a chemical warfare agent (CWA) known as sulfur mustard‚ which destroyed their home‚ murdered their newborn child‚ and resulted in weeks of intense medical care. The use of chemical weapons during World War One revolutionized chemical warfare. Since WW1‚ chemical weapons have grown in popularity. The experience with chemical weapons (CW) in WW1‚ the Northern Yemeni War‚ and Syria demonstrates why the production and
