Answer:
Oxygen
Explanation:
Any Hydrocarbon + Oxygen ----> Carbon Dioxide + H2O (Water vapour, gas, water)
Hey there:
density = 11.3 g/cm³
mass = 15,1 g
Therefore:
D = m / V
11.3 = 15.1 / V
V = 15.1 / 11.3
V = 1.336 cm³
If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
AnswerD is the correct answer. for your information, A describes the neutrons and B describes the electrons. C is wrong.
I don't know how well known/accepted this is (it's in my textbook so I'm guessing it's right), but Sulphur has two forms - the alpha and beta forms ,apparently gamma sulphur exists as well.
The alpha form is rhombic, yellow in color and has a MP of 385.8 K. The beta form is colorless and has a MP of 393 K and is formed by melting rhombic sulphur and cooling it till a crust forms on top. Poke a hole and pour out the liquid inside and you get beta sulphur. The transition point is 369K - below it, alpha sulphur is stable and above it, beta sulphur is stable. Both have helped. I had to pull out an old textbook and that's something that I don't usually do.
