energy source
Explanation:
After wire and filament have been connected, for the conduction of electricity, an energy source is required.
In the energy source, electrical energy is produced.
- The energy source can be a simple electrochemical cell.
- It can be a generator.
- It can also be current from the national grid.
- The energy source produces current which is carried in wire and it powers the filament

Answer:
6M
Explanation:
(Molarity x Volume)concentrated soln = (Molarity x Volume)diluted doln
Molarity dilute soln = [(M x V)conc/V (dilute)] = 1.5L x 12M / 3.0L = 6M final dilute soln
Answer:
374°F
463.15K
Explanation:
This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.
The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;
(x°C × 9/5 ) + 32.
Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.
The conversion of degree celsius to kelvin is given below as;
x°C + 273.15 .
Therefore, x = 190°C = 190°C + 273.15 = 463.15K.
Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.
Answer:
carbon monoxide, CO, can be thought of as having two ordinary covalent bonds between the carbon and the oxygen plus a coordinate bond using a lone pair on the oxygen atom
