Methods
2.- Add 10 drops of hydrochloric acid to the test tube. Using a spatula to take a small
amount of zinc and placed in the test tube.
3.-Using tweezers to hold the end of the strip of magnesium, magnesium ignite a burner.
when the magnesium strip lights magnesium remove the burner.
4.- Add 10 drops of silver nitrate test tube. Take a small piece of copper wire and add it to
the test tube.
5.- Add 10 drops of barium chloride to the test tube, then add 10 drops of sodium sulfate
in the same test tube.
6.- Add 10 drops of lead nitrate to the test tube, now adding 10 drops of potassium iodide
in the same test tube.

Analysis
My hypothesis was correct because it was shown that the 5 different reactions by reactingthe reactants themselves produce different products and different evidence of reaction
Conclusions
The practice in the laboratory showed that my hypothesis was correct at the evidence and
produce different products for each reaction. This practice also helped us understand
different terms as it is a chemical reaction and the different types of reaction.

Cement manufacturing process Cement is produced
in two steps: first,
clinker is produced
from raw materials.
In the second step
cement is producedfrom cement clinker. Ca3SiO5 Combination

Final Reflection
Chemical reactions are important in our daily life because thanks to them have been
consolidated medicines and other things like food. habeces ourselves inadvertently
perform chemical reactions as to make lemon water or cooking and even defecate time or
consume food and why it is important to know and conocewr which is a chemical reaction
that also involves knowing how to balance it and others.
