or simply 2,8 it is isoelectronic with argon
Answer:
1. A circuit is a path that electricity flows along. It starts at a power source, like a battery, and flows through a wire to a light bulb or other object and back to other side of the power source.
2. A series circuit is one that has more than one resistor, but only one path through which the electricity (electrons) flows. All the components in a series circuit are connected end-to-end. A resistor in a circuit is anything that uses some of the power from the cell.
3. A parallel circuit is a circuit in which the electric current passes through two or more branches or connected parts at the same time before it combines again. Compare.
4. BOTH - 1. lightbulb 2. battery 3. switch
SERIES- 1. Ammeter 2. voltmeter
i'm not sure about the rest sorry :(
Answer:
I believe that it would be the third option down.
Explanation:
The thermal energy is in constant motion in the COOLER room, and when the desired temperature in the room is reached, it stops.
Answer:
The molarity of the solution is: 2 M
Explanation:
We calculate the weight of 1 mol of NaOH:
Weight 1 mol NaOH= Weight Na + Weight 0 + Weight H= 23 g+16g+ 1 g= 40g/mol
The molarity is the quantity of moles in 1000ml (1 liter) of solution:
0,5liter-----40 grams NaOH
1 liter----x=(1 liter x 40 grams NOH)/0,5 liter = 80 grams NaOH
40 grams----1 mol NaOH
80 grams----X=(80 grams x 1 mol NaOH)/40 grams= 2 mol NaOH--> 2M
Answer:
by burning the mixture in an electrical furnace to a temp. 640 degree C. to melt both Zinc & Aluminum leaving copper oxide as a powder.
