A mole of Big Macs stacked would reach from the earth to the moon and back how many times?
OLga [1]
A mol=6.02*10^23
so
distance from earth to moon is 230,100 miles
1 big mac is about 2 inches
1 mile=5280 feet=63360inches

230,100 times 63360=14,579,136,000 inches is distance
6.02 times 10^23 times 2=x times 14,579,136,000
divide both sides by 2
6.02 times 10^23=x times 7,289,568,000
divide both sides by 6.02
10^23=x times 1210891694.35159
divide both sides by  1210891694.35159

nata0808 [166]
Answer:
            Ethyl alcohol is soluble in water because <span>ethyl alcohol exhibits dipole-dipole and h-bonding interactions with water.

Explanation:
                   Ethyl alcohol and water are miscible in each other because both are polar in nature and "Like dissolves Like".
                   The bond between oxygen and hydrogen atoms, both in alcohol and water are polar in nature and results in intermolecular hydrogen bond interactions between them as hydrogen bonding results when hydrogen atom in one molecule directly attached to highly electronegative atoms like fluorine, oxygen and nitrogen forms interaction with higly electronegative atom of neighbor atom.</span>

A substance has a atomic number of 80.How many protons and electrons do atoms of the substance have ?what is the substance
Anarel [89]

Answer: Substance is Mercury (Hg)

              number of protons = 80

              number of electrons = 80

Explanation:

Atomic number which is symbolized by "Z" is the number of protons in nucleus of an atom.

Hence,

     number of protons = atomic number = 80

  • By knowing atomic number, we can find the element by using periodic table. Since the atomic number 80, the element is Mercury (Hg).

If the substance is in its neutral state, which means there is no charge on it, then the number of protons equals to the number of electrons of that element.

Hence,

   number of electrons = number of protons = 80
