When in contact with the CARBON DIOXIDE, it constitutes a bright light

activity

Conclusion:

1 . Write a balanced equation for each reaction noticed in this research laboratory. (10 items total, 2 points each) Iron (III) and Birdwatcher (II) Sulfate Solution:

2Fe+3CuSO4=3Cu+Fe2 (SO3)3

Lead (II) Nitrate and Potassium Iodide Alternatives:

Pb (NO3)2+2KI=PbI2+2K (NO3)

Magnesium Metal Ribbon and Hydrochloric Acid Option:

Mg+2HCl=MgCl2+H2

Electrolysis of Water:

2H2O=2H2+O2

Burning up Magnesium:

2Mg+O2=2MgO

2 . If you were to measure the mass of magnesium and hydrochloric chemical p before incorporating them inside the test conduit, how will that mass compare to the mass of reactants kept in the evaluation tube after the reaction? Describe your response and how it corresponds to the law of conservation of mass. (5 points)

It would be the same mass, mainly because according to law of conservation of mass: Strength cannot be developed nor ruined, only improved. But , due to the fact that this happened in an open test tube having a gaseous item, the mass would almost certainly be much less after combining them than previously combining all of them.

3. One of many reactions you conducted can in fact be grouped as TWO different types of reactions. Which...
