“If a certain metal is cooked, it will conduct electricity better”
- this is a hypothesis, since the statement is kind of vague...”certain metal”...and is written in an “if-then” format.
The amount of electric current that passes through a conductor is directly proportional to the voltage and is described as V = IR
- laws are usually scientific understanding that we’ve tested so much that we’ve come to a conclusion that can often be written out as a mathematical relationship. Hence, the “V = IR”
Electricity is the flow of electric charge in the form of electrons moving through a circuit
- this is a theory. I would give an explanation but I’m out of time.
1 mole of N2 produces 2 moles of NH3 OR... 14 x 2 grams of N2 produces 2(14 +3) grams of NH3 1 gram of N2 produces 34/28 grams of NH3 therefore, 56 grams produce (34/28 )x 56 =68 grams of NH3
Chlorine is a member of the halogen family. Halogens are the elements that make up Group 17 (VIIA) of the periodic table, a chart that shows how elements are related to one another. They include fluorine, bromine, iodine, and astatine.
