Answer: Ions are an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. They are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
Explanation:
When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.

Specifically, what do we mean when we say that a scientific hypothesis must be testable? It must be able to be proven wrong. ... A scientific fact is something that observers can observe and agree to be true. A hypothesis is an educated guess that answers a question.
Answer:
R = 12 ohms
Explanation:
It is given that,
Supply voltage is 12 V
Current in the circuit is 1 A
We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :
V = IR

So, the resistance of the circuit R is 12 ohms.
Answer:2,204 pounds Ibuprofen must the factory use to fill this order
Explanation:
Amount of Ibuprofen in 1 tablet = 200 mg
Amount of Ibuprofen in 5,000,000 tablet = 
1 g = 1000 mg
Grams of Ibuprofen = 
1 g = 0.002204 pounds
Pounds of Ibuprofen required to fulfill the order:

2,204 pounds Ibuprofen must the factory use to fill this order
