25 x 10.5 = 262.5
So the approx. is 260 g which is answer D.

Explanation:
it fast go to the atmosphere
Answer: Imidogen
Explanation: I just looked it up.
Answer:
Explanation:
Heat can transfer between objects in two different ways. Generally, heat will travel from places of higher heat to places of lower heat.
The first is conduction. This is when the object being heated and releasing heat are in direct contact. Not as much heat is lost in this process, since the thermal energy has nowhere else to go except for the object it is touching. An example would be putting a kettle on a hot stove, but it could also be grabbing a cold pole with your relatively warm hands.
The second is convection. This is where heat is radiated into the air, and thus, transferred by the air, to another object. The actual heat that you feel is actually electromagnetic waves, and its transfer from an object is called electromagnetic radiation. Convection is the heat you feel from a near fire or a space heater. This is also why wind is present in our atmosphere.
There is also radiation. This is caused from the burning or breaking down of a substance. This might come from the sun.
I hope I did enough to deserve the 45 points!
Answer:
(4) option is correct
Explanation:
Given that,
The conformation of 2-methyl-3-pentanol, as viewed along the C₂-C₃ bond.
We need to find the Newman structures
Using given structures
The structure of 2- methyl-3- pentanol is shown in figure.
Through C₂-C₃ carbon shown the structure of Newman projection in figure.
Here, carbon 2 is in front side and carbon 3 is in back side in the figure.
Hence, (4) option is correct.
