Answer:
Q = 1.5 kJ
Explanation:
It is given that,
The specific heat for aluminum is 0.900 J/g°C
Mass of sample, m = 3.8 g
Initial temperature,
Final temperature,
We need to find the heat released. The amount of heat released is given by the formula:
or
So, the correct option is (A) i.e. 1.5 kJ.
Answer:
B. chemical
Explanation:
Chemical change cannot go back to its original form
Answer:
Whenever you are doing calculations with gases and temperature, you must convert the temperature from C into Kelvin. Then, just plug in your values and do the calculation. So, for the first one,
32C + 273 = 305 K
63C + 273 = 336 K
Then, P1/T1 = P2/T2
575 torr / 305 K = P2 / 336 K
P2 = 633 torr
For the second one:
P1/T1 = P2/T2
575/305 = 5750 / T2
T2 = 3050 K
Answer:
Definition of Inert. An inert chemical is one that is stable and unreactive under specified conditions. ... However, most of the noble gases have now been observed to form compounds, although generally under unusual conditions. Helium and neon are highly inert; they form no compounds.
