Answer:
iron (III) oxide is a gas
Answer:
mole
Explanation:
The mole in chemistry is used to represent the amount of any substance. Just like quantifying everyday things like a dozen, score, gross etc, it is a convenient unit of quantity of particles. A mole denotes 6.02 x 10²³particles of a susbstance.
Therefore, a mole is the standard unit(SI) for the amount of isopropyl alcohol in a beaker.
the fire spreading is what represents the form of heat transferring from one atom to another within an object and direct contact
Answer:
plaster is important because of the many uses you can make out of plaster
The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.
Density of a substance is
Density = Mass / Volume
= 5.34/5
= 1.07
Density of water = 1
Specific gravity = Density of substance/density of solvent
Specific gravity = 1.07 / 1
Specific gravity = 1.07
Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.
If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.
