Chemical Equation for Alka Seltzer Tablet

# data[].attributes.body
3NaHCO3 + C6H8O7 → C6H5Na3O7 + 3CO2 + 3H2O.

This is the chemical equation for Alka Seltzer tablet. The fizz is carbon dioxide being released.

# data[].attributes.body
This is an alka seltzer tablet being dissolved in water. There is fizzing formed which shows that there is a chemical reaction being formed.

# data[].attributes.body

Iodine and Starch Experiment | Iodine Experiment | Starch Experiment | Science experiments for kids

# data[].attributes.body
This is a chemical reaction between iodine and starch. When the iodine is added to starch there will be a very intense black-blue color. "Iodine is not very soluble in water, therefore the iodine reagent is made by dissolving iodine in water in the presence of potassium iodide"

Dissolving Calcium Chloride: An Exothermic Process

# data[].attributes.body
Dissolving Calcium Chloride in water causes and exothermic reaction, this means that the temperature changed to be hotter and this is the evidence of a chemical change. You can measure this by using a thermometer to see the CaCl2 + H20.

Pb(NO3)2 + KI = Lead Nitrate. The reason that this happens is because... "A precipitation reaction occurs when an ionic substance comes out of solution and forms an insoluble (or slightly soluble) solid. The solid which comes out of solution is called a precipitate. This can occur when two soluble salts (ionic compounds) are mixed and form an insoluble one—the precipitate" (Wiki/General_Chemistry).

# data[].attributes.body
This is another example of a chemical reaction where a solid is formed, also known as the precipitant. It is silver nitrate being added to table salt and this forms the new solid.

Baking Powder and Water. "Using chemical change to identify and unknown baking powder was the only substance that reacted with water to produce a gas. ... It is a combination of substances that, when mixed withwater, react to release carbon dioxide gas. Baking powder can be made from baking soda, cream of tartar, and corn starch."

Think small when burning wood in your fireplace #ChimneySafetyWeek

# data[].attributes.body
This is an example of a chemical change because the wood is being burned by fire and ashes are formed and so is smoke, this smoke travels up through the chimney. The ashes cannot be turned back into the wood which proves even more thoroughly that this was a chemical change that took place.
