Answer:
D) she is confident and has already made plans
Answer:
0.933 L
Explanation:
Since the pressure is the same, we use the equation ![\frac{V_{1}}{T_{1} } = \frac{V_{2} }{T_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7B1%7D%7D%7BT_%7B1%7D%20%7D%20%3D%20%5Cfrac%7BV_%7B2%7D%20%7D%7BT_%7B2%7D%20%7D)
V = Volume
T = Temperature
Since we are given the temperature in Celsius, we need to convert it to Kelvin by adding 273:
-55.0 + 273 = 218
40.0 + 273 = 313
![\frac{0.650}{218} = \frac{x}{313}](https://tex.z-dn.net/?f=%5Cfrac%7B0.650%7D%7B218%7D%20%3D%20%5Cfrac%7Bx%7D%7B313%7D)
![0.933 = x](https://tex.z-dn.net/?f=0.933%20%3D%20x)
The gas will occupy a volume of 0.933 L.
(Side note - If the temperature increases, the gas will want to expand, leading to a higher volume.)
Answer: Part 1: The reaction is considered as replacement reaction and produce preciptate.
Part 2: Due to Mg is more active than Al.
Explanation:
Part 1: the reaction is replacement reaction due to the ions is replaced with each other as this equation shows:
MgCl2 + Na2CO3 → MgCO3 + 2NaCl
and MgCO3 is a white precipitate.
Part 2:
Al reacts with CuCl2 because Al is more active than Cu.
Al can not react with MgCl2 because Mg is more active than Al.
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.

Explanation:
They will eventually reach equilibrium. But, before that, the thermal energy particles of the COLD milk will slow down the hot cocoa.
