Question

alex:
wait—why copper?
riley:
copper is a great conductor. it lets electricity flow easily.
thats why its used in almost every circuit board.
dr. sparks: (enters dramatically)
did someone say copper? ah, the unsung hero of
electronics! but beware—it has a dark side too!
alex:
uh-oh. whats that green stuff?
dr. sparks:
this, my young engineers, is copper chloride. it forms
when copper reacts with certain chemicals. its used in
etching circuit boards—but its also toxic!
riley:
toxic? like dangerous?
dr. sparks:
indeed! if copper chloride or copper from mines gets into
water, it can harm fish, plants—even people. too much
copper in drinking water can cause stomach problems and
liver damage.

1. what is copper used for in electronics?
2. what is copper chloride and why is it dangerous?

Explanation:

1. For the first question:

Copper is used in electronics because it is a great conductor. It allows electricity to flow easily, which is essential for the functioning of electronic circuits.

1. For the second question:

Copper chloride is formed when copper reacts with certain chemicals. It is dangerous because if it gets into water, it can harm fish, plants, and even people. Too much copper in drinking water can cause stomach problems and liver damage.

Answer:

1. Copper is used in electronics because it is a great conductor. It allows electricity to flow easily.
2. Copper chloride is formed when copper reacts with certain chemicals. It is dangerous because if it gets into water, it can harm fish, plants, and even people. Too much copper in drinking water can cause stomach problems and liver damage.
