Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

How do enzyme work in a chemical reaction?
It acts as a catalyst. Using less energy while producing similar amount of products at a shorter periodof time.
What is used in bioleaching?
bacteria
What is used in phytomining?
Plants
How are metals extracted through displacement method?
More reactive metals replace a less reactive one.
These compounds do not conduct electricity at solid state but can conduct electricity aqueous state.
Ionic compounds
What metal ion produces lilac color flame?
Potassium (K)
What are valence electrons?
electrons at the outermost shell.
It has similar number of protons and electrons but different atomic mass.
Isotopes
Who proposed the "Plum Pudding Theory" of atom?
Joseph John (J.J.) Thomson
Give two reasons why Kr is unreactive.
it has full outermost shell. It is already stable, does not need to react.
What is the electron configuration of Calcium (Ca)?
2,8,8,2
How many shells does Sodium (Na) has?
3
When metals are bonded with non-metals, what type of bond is formed?
ionic bond
What bond is in the molecule of water?
covalent bonds
It is the positive ion.
Cation
What does metallic bond have that other type of bonds doesn't have?
delocalized electrons
Give 3 reasons why Francium is the most reactive element?
bigger size more shells, weaker electrostatic force, easy to donate valence electron
Which is the most reactive non-mental element.
Fluorine
It is the 7th group of elements.
Halogens
The process by which particles move from an area of higher concentration to an area of lower cconcentration.
diffusion
The process by which gas changes into solid.
deposition
