ENERGY TRANSFORMATION is when energy is changed from one type to another
Oxidation: a chemical change resulting form a reaction with oxygen
Endothermic:a reaction that takes in energy
Exothermic: a reaction that releases energy
Decomposition:chemical change whereby a molecule breaks down into simpler moles clues or elements
Subscript:written underneath or below
Answer:
B. The reactants will react to produce more H₂O
Explanation:
Given the reaction
2H₂+O₂→2H₂O
A decrease in the amount of H₂O will cause the reaction to produce more H₂O. When you change something, the reaction seeks to undo that change.
Answer: Option (B) is the correct answer.
Explanation:
Marble is also known as calcium carbonate and its chemical formula is 
.
When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.
The reaction is as follows.
Whereas vinegar being a weak acid will not react with glass, copper and steel.
Aspartame is an artificial sweetener that is added to food and beverages as a substitute to table sugar or sucrose. It is apparently 200 times sweet than sucrose. It is also more preferable especially in the food industry because its sweetness lasts longer than sucrose does. Aspartame is a methyl ester from two acidic amino acids, aspartic acid and phenylalanine. It also constitute a small portion of methanol. The composition is 40% aspartic acid, 50% phenylalanine and 10% methanol. This compound was accidentally discovered by James Schlatter when he was trying to test an anti-ulcer drug.
