ABYC Corrosion exam with answers
GFCI stands for... - ....🔰VERIFIED ANSWERS.... ✔✔Ground Fault Circuit
Interrupter
T/F A galvanic isolator WILL block stray AC. - ....🔰VERIFIED ANSWERS....
✔✔False. A galvanic isolator WILL NOT block AC. It will only blocks stray DC
that is moving through the green grounding conductor.
T/F An isolation transformer makes a galvanic isolator unnecessary. - ....🔰
VERIFIED ANSWERS.... ✔✔True.
An isolation transformer works through electromagnetic _________. - ....🔰
VERIFIED ANSWERS.... ✔✔Induction
A reverse polarity indicator is placed between which two wires? Why? - ....🔰
VERIFIED ANSWERS.... ✔✔White neutral and green grounding.
If the black hot and white neutral are reversed, electricity will flow through the
white neutral illuminating the indicator light and leaving through the green
grounding conductor.
Bonding wires shall be at least #__ AWG - ....🔰VERIFIED ANSWERS....
✔✔#8 AWG
,Electrolytic corrosion is commonly known as: - ....🔰VERIFIED ANSWERS....
✔✔Stray-current corrosion
Stray-current corrosion is technically called: - ....🔰VERIFIED ANSWERS....
✔✔Electrolytic corrosion
Matter can exist as a - ....🔰VERIFIED ANSWERS.... ✔✔Solid, liquid, or gas
Matter is made from - ....🔰VERIFIED ANSWERS.... ✔✔Molecules
Molecules are made of - ....🔰VERIFIED ANSWERS.... ✔✔Atoms
Atoms are made of - ....🔰VERIFIED ANSWERS.... ✔✔protons, neutrons,
electrons
The atom is electrically - ....🔰VERIFIED ANSWERS.... ✔✔Neutral. That's
because the particles that comprise an atom balance each other.
the outer shell of an atom is called the - ....🔰VERIFIED ANSWERS....
✔✔Valence shell
When the valence shell of an atom is completely filled, the atom is in its most
______ state. - ....🔰VERIFIED ANSWERS.... ✔✔Stable.
Atoms that have gained or lost an electron are known as - ....🔰VERIFIED
ANSWERS.... ✔✔Ions
, T/F Ions can have positive or negative charges? - ....🔰VERIFIED
ANSWERS.... ✔✔True.
Define Ionization - ....🔰VERIFIED ANSWERS.... ✔✔The process by which an
atom or molecule acquires a charge.
What are the two types of chemical bonds? - ....🔰VERIFIED ANSWERS....
✔✔Covalent and ionic
In covalent bonds, atoms form chemical bonds by _______ electrons. - ....🔰
VERIFIED ANSWERS.... ✔✔Sharing.
E.g. water, H2O
In ionic bonds, atoms form chemical bonds by _______ electrons. - ....🔰
VERIFIED ANSWERS.... ✔✔Giving up or gaining electrons.
The atom giving an electron become a positive ion. The atom gaining an
electron becomes a negative ion. Oppositely charged bodies are attracted to
each other, bonding them together.
E.g. Sodium Chloride, NaCl, table salt.
