the metal that produces the most hydrogen gas is considered the most reactive‚ in this experiment magnesium was most reactive. And‚ similarly‚ if the metal that produces the least hydrogen gas is considered the least reactive‚ in this experiment copper was the least reactive. While this does follow the trend of the Reactivity series roughly‚ it is not exact. As seen in the graph‚ the 2nd most reactive metal was calcium‚ as it produced on average 58.17mL of hydrogen gas (the 2nd largest volume of gas)

Remember that most bases do not dissolve in water. But if a base can dissolve in water‚ it is also called an alkali. Reactive metals Acids will react with reactive metals‚ such as magnesium and zinc‚ to make a salt and hydrogen: • acid + metal → salt + hydrogen The hydrogen causes bubbling during the reaction‚ and can be detected using a lighted

Catalysis Lab: Laboratory Write Up Problem/Question: What happens to the amounts of gas produced in a catalyzed reaction of Hydrogen Peroxide when the catalyst is mixed with an acid? Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating the

important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond so that the electrical charge is unevenly distributed. The area of the molecule containing oxygen has a slightly negative charge‚ and the areas containing hydrogen have slightly positive charges. Polar Compound: a compound with one side having a negative charge and the other side a positive charge Hydrogen bonds form between water molecules. • Six Unique Properties of Water 1.

Molar Volume of a Gas Objective: The objective is to determine the volume‚ of one mole of hydrogen gas at STP using experimental data‚ known mathematical relationships‚ and a balanced chemical equation. Theory: The goal of this lab is to find the volume of one mole of hydrogen at STP. The experimenters will be working with hydrochloric acid and magnesium to find the objective. The acid in this lab will react to the magnesium and cause the water in the eudiometer to rise because of the reaction

properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape‚ water is considered as a polar molecule. Because oxygen is very electronegative‚ it pulls hydrogen’s electrons towards it‚ causing oxygen to become partial negative. The hydrogen atoms then will have fewer electrons towards its own nucleus‚ therefore making it partial positive. Since positive charge and negative charge attracts each other‚ the molecular formation of H2O will result hydrogen bonding. Each water

Grades K-5 Pencil Electrolysis Introduction: The process by which we separate the elements hydrogen and oxygen from water is called electrolysis. The word "lysis" means to dissolve or break apart‚ so the word "electrolysis" literally means to break something apart (in this case water) using electricity. It is difficult to break up water into it’s elements lots of energy is needed to do that. Through a chemical means though‚ we can separate the compound of water into the elements that combine to
