Answer:750.550mL
Explanation:
V1/T1=v2/T2
V1=540mL
T1=-55°c to convert to Kelvin
273-55=218k
V2=?
T2=30°c to convert to Kelvin
273+30=303k
540/218=v2/303
Cross multiply
218v2=540×303
V2=540×303/218
V2=163620/218
V2=750.550mL
The answer is c. Calorimeter
A.) true
Because the rocks are formed near lava so the texture would be smooth
I think the answer is B, the metal loses valence electrons to the nonmetal.
Answer:
1056.8 kJ
Explanation:
A sample of gas in a cylinder is provided with 623.9 kJ of heat. By convention, when the gas absorbs heat, it takes a positive sign, so Q = 623.9 kJ.
A piston then compresses the gas by doing 432.9 kJ of work to the gas. We work is done on the gas, it takes a positive sign, so W = 432.9 kJ.
The change in the internal energy (ΔU) is:
ΔU = Q + W
ΔU = 623.9 kJ + 432.9 kJ = 1056.8 kJ
