Answer:
15.4: Lewis Structures: Counting Valence Electrons
Explanation:
Answer:
C. A Spring Scale
Explanation:
Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!
Answer:
When a reduction reaction and an Oxidation reaction takes place due to passing of current through water the molecules of water split into the compounds. Where it is made up of hydrogen in its state of gas and also Oxygen in its state of gas this method is most vastly is known as electrolysis.
In this process a certain direct current is passed from inside water. This direct current value can be near about 1.23 voltages the reaction that happens inside is given below.
2 Water---> Oxygen + 4 hydrogen ions + 4 Electrons
2 Hydrogen ions + 2 electrons ----> hydrogen gas
Must be C because the liquid fuel is Codium nitrate to be used in rocket engines
