You're writing a letter to other stars (suns) in our neighboring galaxy. You'll tell them about the
fun and exciting trip you took through a plant
(photosynthesis). Make sure you include
everything you meet on the journey (reactants
and products) and places you've been (where is
the sun before it's absorbed in the plant and
where does it go once it's absorbed).

I need help please
It’s for science

he would use the colour black

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
