Answer:Do you think the climate change has only to do with human society or is it also occuring "naturally"?
I was in Germany on december of last year (2011) and I was surprised because it didn´t snow. I read about the melting of the principal glacier and it will raise the ocean water levels. There are people that blame only human being for the climate changes but I wish to know how much we are responsible for that.
Climate Change
Explanation:
PbCl2 and PbCl4
Empirical formula is when the molecular formula is reduced (each element) by the same number until you are unable to do so any further.
CH2O cannot be further reduced, but C3H6O3 can all be divided by 3 making it CH2O (same empirical formula)
I think these are the right answers sorry about 5...
1 are determined by the atomic structure and crystal chemistry of the minerals. or hardness
2 acid based reaction
3 rust
4 Examples of physical changes are boiling, melting, freezing, and shredding.
5 I don't know
Answer:
0.16 J/g℃
Explanation:
We have the following data:
heat = 1,200 J
mass of metal = m = 150 g
change in temperature = ΔT = 50.0℃
The heat absorbed is calculated by using the following equation:
heat = m x Cp x ΔT
So, we introduce the data in the equation to calculate the specific heat of the metal (Cp), as follows:
Cp = heat/(m x ΔT) = (1,200 J)/(150 g x 50.0℃) = 0.16 J/g℃
