Answer: Both are only physical changes. •
Explanation:
Answer:
.259 g
Explanation:
PV = nRT
n = PV / RT
= .986 x 0.144 / .082 x 293.6
= .005897 moles
= .005897 x 44 g
= .259 g
Answer:
A. Calorimeter
Explanation:
A calorimeter is an apparatus that can be used to measure the quantity oh heat in a chemical reaction or the amount of heat that accompanies a physical change and also determine the specific heat capacity of a substance.
It is used extensively in physics, chemistry and the study of thermodynamics. In its simplest form, a calorimeter contains a thermometer which is attached to a container filled with water and suspended above a combustion chamber.
Answer:
The key difference between rhombic and monoclinic sulphur is that the rhombic sulphur is the most stable allotropic form of sulphur that exists as rhombic octahedral crystals whereas the monoclinic sulphur exists as long, needle-shape prisms but, it is stable only at temperatures between 96◦C and 119◦C.
