Which observation would be evidence that heat was transferred by radiation?

a) a person feels colder when the wind is blowing.

b) a pan on a stove heats up the food placed in it.

c) warm air in the kitchen rises to the second floor of the house.

d) a car with the windows rolled up gets very hot on a summer day.

pls me

If I were to say by radiation it would most likely be the answer D because the sun has radiation which heats up anything on a summer day.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
