Synthesis & Friends 5th Period
Ricke 5th Period. MLCHS. 1/22/15
A: Synthesis Introduction
A reactant is the starting substance in a chemical reaction.
A product is the substance formed during a chemical reaction.
A coefficient is the number written in front of a reactant or product, in a chemical equation; in a balanced equation describes the lowest whole-number ratio of the amounts of all reactants and products.
Now what can you see that causes a chemical reaction? well first as you add all these things into a mixture of chemicals and a graduated tube, you will be able to see some crazy things, like color change, temperature change, gas(es) created, and formation of solid(s).
B: Analysis of Reactions
A: Color changed and heat/smoke was emitted. B: A solid compound containing water molecules combined in a definite ratio as an integral part of the crystal. Often used in combination. C: Double.
2. 2KI + Pb(NO3)2 -> 2KNO3 + PbI2
There is a color change in this reaction
It is an example of double replacement and when the term “reacts with” is seen as a plus sign in a balanced chemical equation.
3. A: Very bright light. B: you can tell that oxygen needs another oxygen to be able to help balance out if it is alone, and to fuel the flame. C: Synthesis D: 2Mg + 02 → 2MgO
4.A. A gas was produced when they were combined B.Cation is a positively charged ion. C. An anion is a negatively charged ion. D. This experiment would be an example of a single replacement E. The name for the outcome would be ZnCl2+H2 for it.
5.bubbles formed and the flame was reignited
A catalyst is something that is added to the reaction to speed up the process yet it has no effect on the outcome.
2H2O2 -> 2H2O + O2
dissolving salt: physical
