Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.

Scientific Notation consists of 2 parts
1. the first part: the first digit followed by the decimal point
2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point
To add/subtract, the exponents must be the same and then add/subtract the coefficient
- convert the largest exponent
- subtract the coefficients
Isotopes are elements with the same number of protons but different number of neutrons
Answer:
Impurities will be trapped in the crystals of the benzoic acid crystallized in this manner.
Explanation:
After benzoic acid is dissolved in hot water, it should have been allowed to cool gradually before it is transferred into an ice bath.
This gradual cooling will aid the separation of impurities so that when the vessel is now submerged in an ice bath, only pure benzoic acid is recrystalized.
If the vessel is immediately submerged into an ice bath, impurities will be trapped in the crystals of the benzoic acid.
The chlorine usually forms a Chloride ion.
The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.
What do you mean by Chlorine forming an ion?
Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.
The chloride ion is the anion Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.
