Answer:
the terminator because i did this test
Explanation:
The charge of a helium atom is zero
It is neutral because
The number of unit negative charges = number of unit positive charges
One unit negative charge = -1.6 x 10^(-19) which is basically the charge of an electron
One unit positive charge = +1.6 x 10^(-19) which is basically the charge of a proton
A helium atom has 2 protons and 2 electrons, so it is neutral
NOTE: an alpha-particle (He2+) is a charged helium atom it has 2 protons and 0 electrons. Charge of an alpha particle = +3.2 x 10^(-19).
It would be atomic masses of the same atoms, and that atoms will be isotopes.
Answer:
Carbon and Hydrogen
Explanation:
So the C stands for Carbon and H is for Hydrogen. Methane (CH4) is made up of one atom of Carbon and 4 atoms of Hydrogen.
Hope this helps
<u>Answer:</u> The molality of 
solution is 4.013 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg.
The formula used to calculate molarity:
.....(1)
Given values:
Given mass of = 20.0 g
Molar mass of = 62.3 g/mol
Mass of solvent = 80.0 g
Putting values in equation 1, we get:
Hence, the molality of solution is 4.013 m
