Answer: I believe it is B
Explanation:
because it states that a chemical compound always contains exactly the same proportion of elements by mass
Answer:
9 atoms
Explanation:
Explanation: In 1 formula unit of Al(NO3)3 , there are (clearly!) 9 atoms of oxygen, 3 nitrogen atoms, and 1 aluminum atom. I have gone on before that the mole ( NA , Avogadro's number) is simply a much larger number, i.e. NA = 6.022×1023 .
Heat capacity
Explanation:
The heat capacity is the energy required to raise the temperature of a substance.
With the value of this amount of heat known, we can know the amount of heat that will cause a particular temperature change when added or removed from a substance .
- Heat capacity is a function of mass and specific heat capacity of a body
- The specific heat capacity measures the amount of heat required to the raise the temperature of 1g of a substance by 1°C or 1K
- Different substances have different specific heat capacities and hence will require various amount of heat to change their temperature.
- Metals usually have low heat capacity because they are good heat conductors and would require little amount of heat to change their temperature.
