Answer:
The answer to your question is 1137.45 kJ
Explanation:
Data
mass = 424 g
T1 = 22.6°C
T2 = 149°C
Clw = 4.184 J/g°C
Cv = 2.078 j/g°C
Latent heat = 2257 J/g
Process
1.- Heat of liquid
Heat = (424)(4.184)(100 - 22.6)
Heat = 137308.8 J
2.- Calculate latent heat
Latent heat = (424)(2257)
Latent heat = 956968 J
3.- Heat of vapor
Heat = (424)(2.078)(149 - 100)
Heat = 43172.5 J
4.- Total heat
Heat = 137308.8 + 956968 + 43172.5
Heat = 1137449.3 J = 1137.45 kJ
Answer:
Chemical, electrical, thermal, & radiant
Explanation:
A battery is a device that stores chenical energy and converts it to electricity. The diagram portrays said electricity powering an incandescent light bulb, which work by using an electrical current to heat a filament until light is produced.
Answer:

Explanation:
0.062502343837894 grams in one mole of oxygen
Answer:
C. Yes, if each sample contains 6.02 x 10²³ atoms.
Explanation:
It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.
6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.
- If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance.
- If they contain lesser amount of atoms, then it is not up to one mole of substance.
- But if it is greater, then, we can have even more than one mole of substance.
A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.
They are all part of the same group on the periodic table hopw this helps
