Front (Question)

Chemical Changes

Back (Answer)

New Color appears Heat/Light produced (hot) or absorbed (cold). Bubbles of gas are formed A solid material precipitate. (the solid substance that appears when specific two substances mix) Difficult to reverse

Front (Question)

reactants vs products

Back (Answer)

reactants r the elements that make the products

Back (Answer)

Lose electrons and have a positive net charge

Front (Question)

what’s a Anions

Back (Answer)

Gain electrons and have a negative net charge

Front (Question)

Reactivity of metals vs nonmetals in periods

Back (Answer)

Reactivity of metals increases from right to left. Reactivity of nonmetals increases from left to right.

Front (Question)

Reactivity of metals vs nonmetals in groups

Back (Answer)

#10

Front (Question)

what’s a Path

Back (Answer)

a complete trip to and from the cell(s) with no back or repeat step

#11

Front (Question)

Series Circuit vs Parallel

Back (Answer)

A Series Circuit is where charges have only 1 path to follow. A Parallel Circuit is where charges have more than 1 path to follow

#12

Front (Question)

What happens when a load goes out in a parallel vs series circuit?

Back (Answer)

Series– All loads in the circuit will go out Parallel circuits– All loads in the circuit will stay the same brightness

#13

Front (Question)

How are Ammeters connected

Back (Answer)

Series

#14

Front (Question)

How are Voltmeters connected

Back (Answer)

Parallel

#15

Front (Question)

If the Ammeter/Voltmeter shows a negative number what does that mean?

Back (Answer)

The wires were incorrectly connected and needed to be switched

#16

Front (Question)

If a circuit only has one load, how must it be wired

Back (Answer)

In series

#17

Front (Question)

what’s a Combination Circuit

Back (Answer)

Circuit in which it has both elements of series and parallel

#18

Front (Question)

Unsafe use of circuits can cause

Back (Answer)

Short circuiting

#19

Front (Question)

What safety device can be used when the current exceeds a safe limit

Back (Answer)

A fuse will heat up and melt (breaking the circuit)

#20

Front (Question)

Automatic fuses

Back (Answer)

Circuit breakers

#21
