Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.
<h3>What is a double bond?</h3>
A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.
A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.
Therefore, hydrogen molecules cannot form a double bond.

That's your </span>answer!!
Hope I helped!! :)
9.05 E-22 g. ~ 10.0 E-22 g Cu
For C, they would be the same. At the equivalence, you have equal moles of both the acid and the base.
An original sample of K-40 has a mass of 25.00 grams.
After 3.9 m 109 years, 3.125 grams of the original sample remains unchanged.
What is the half-life of K-40?
First step is to determine the remaining decimal amount.
3.125 grams /25.00 grams = 0.125
Second step is to determine the number of half lives.
(1/2)^n = 0.125
N log (1/2) = log 0.125
N = 3 years
