Answer:
Helium
Explanation:
The first ionization energy varies in a predictable way across the periodic table.
The correct answer is light...
The distance of the earth to the sun in Mm = 1.5 x 10⁵
<h3>Further explanation</h3>
Given
The distance of the earth to the sun : 1.50 x 10⁸ km
Required
The distance in Mm
Solution
In converting units we must pay attention to the conversion factor.
the conversion factor :
1 kilometer(km) = 10⁻³ megameter(Mm)
So the distance conversion :
1.5 x 10⁸ x 10⁻³ = 1.5 x 10⁵ Mm
A and d is physical, b and c is chemical
<span>(2.00 L) x (0.100 M HCl) / (1.50 M HCl) = 0.133 L</span>
