oxygen around the combustion will remain and we heat and light. By analyzing the gas ready to prove our hypothesis which is the chemical reaction between baking soda (a base) and vinegar (weak acid) is carbon dioxide. As is heavier than air‚ facing the match expels oxygen. Without oxygen the flame goes out. When you mix baking soda and vinegar becomes an effervescence that seems fun during this reaction shows carbon dioxide‚ carbon dioxide is formed by a molecule of carbon and two oxygen and is in our lungs expel air when breathe in all

Keeping the vehicle wet will leave ugly water spots.Using pure vinegar will do a great cleaning for the tires. Use a hand towel and pour vinegar into it‚ Wipe the tire and rims well. Dry and watch it shine!.My final step to great cleaning is‚ when cleaning your vehicle windows use Windex and news paper. Yes news paper. You will get a thorough and clear

Purpose: In this experiment‚ the purpose was to have found out how different chemical solutions help or harm radish plant growth when the seeds of the radish plant are soaked in said solutions prior to planting. Background: The IRP project I am doing is based off the subject of seed germination. The seeds I will be planting are cherry belle radish seeds‚ freshly bought. Instead of planting the seeds in soil like it is normally done‚ the plant seeds will be placed on paper towels to grow for better

Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited reactants. It is hypothesized that the limited reactant of this

INTRODUCTION Differences between acids and bases An acid-base reaction is based on the reaction involving the ionization of water H2O -> H+ + OH- This means that water can break apart into a hydrogen ion and a hydroxide ion. These two ions can also join together to form a water molecule. When a strong acid is placed in water‚ it will ionize completely‚ and break down into its constituent ions in which one of it a hydrogen ion. When a strong base is placed in water‚ it will ionize

Chapter I THE PROBLEM Introduction Rubber is an elastic hydrocarbon polymer which occurs as a milky emulsion (known as latex) in the sap of a number of plants but can also be produced synthetically. The major commercial source of the latex used to create rubber is the Para rubber tree‚ Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Other plants containing latex include figs‚ euphorbias and the common dandelion
