It’s carbon and it’s heat value
Sry,I only know the answer of q2
Chlorine is a non metal because it is bad conductor of heat and sodium is a metal because it is good conductor of heat.
The 3 ways in which metal is different from non metal are given below:
1)metal are good conductor of heat but nonmetal are bad conductor of heat.
2)metals are malleable but non metal aren't malleable.
3)metals are generally ductile but non metal aren't ductile.
Hope it will helpyou!
Answer:
80 J
Explanation:
PE = mgh
PE = (4 kg)(9.8 m/s^2)(2 m)
PE = 78.4 J and with sig figs, it would be 80 J
Answer:
Diffusing the gradient ensures that most of the molecules in high concentration zone will wind up in the previously low concentration by the spontaneous movement of small molecules.
Explanation:
A gradient of concentration is the difference between in concentration of one place / area substance to different area. Having a molecule flow down its concentration gradient means moving the molecules from hypotonic areas to the concentration hypertonic areas
Diffusing the gradient ensures that most of the molecules in high concentration zone will wind up in the previously low concentration by the spontaneous movement of small molecules.
