Different Types Chemical Reaction Types and Equations
Purpose:
The purpose of this lab experiment is to examine different types of chemical reactions such as Decomposition reaction, Synthesis reactions, Combustion reactions, and different Chemical equations. The experiments were conducted online using Late Nite Labs.

Materials:
Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

Procedures:
The first experiment was the Synthesis lab.
1. Using the Scale weighing the crucible empty which weighted 88grams,

Which totaled 93.00 grams then decreased 1.673 grams them the reaction took place.
2. The color of the copper carbonate hydrate as it was heated can help identify the product?
The final color ended up being black which was CuO

3. Given that mass was lost from the copper carbonate hydrate during heating, in this decomposition reaction, how many moles of solid product were produced? The molecular weight of the solid product is 79.545 g/mol (moles = mass / molecular weight).
There were 4.183 x 10^-20 of solid product produced
4. Copper carbonate hydrate produces 1 mole of water (MW = 18.015 g/mol) was for every mole of solid product (MW = 79.545 g/mol) produced. Given that 3.327 g of product was produced during the reaction, how many grams of water were released as water vapor? (moles = mass/molecular weight).
From observation it appeared 1.673 grams of water were released as water vapor.
5. Write a balanced equation for the decomposition of copper carbonate hydroxide hydrate.
Zn(s) + 2 HCl (aq) which led to ZnCl2 (aq) + H2(g)

Experiment

The first experiment was a Synthesis reaction, this was done by burning the substance magnesium; the substances reacted to form one compound, which ended up being heavier than the first original mass of the magnesium, the final product was known as magnesium oxide. The second experiment that was conducted was the Decomposition reaction, which actually eliminated chemical elements by burning them off, therefore reducing the weight of the final product by 1.673 grams. The third experiment was known as single displacement, by adding the chemical hydrochloric acid to zinc it created a chemical reaction which actually increased the temperature, as well as the pressure within the flask. The last experiment that was conducted was known as double displacement, this experiment involved the exchange of bonds, between the two sodium hydroxide and nickel. The Nickel was forced to group together when it was placed into the sodium hydroxide, instead of mixing with the compound it would rather keep to
