What does the diagram show about phases and
the phase of the substance as it is heated? check
all that apply
the substance is a gas at more than
2,000°c
the particles are close together but move in
different directions between 0°c and
2.200°c
the attractions between the particles
increase in region 2.
m. the speed of the particles increases in region
temperature (°c)
the substance does not exist as a solid

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
