Answer:
false it's 24 hours long.
Galactic recycling is a natural phenomenon in which the stars expel some gas into the space so that it would mix with the interstellar medium. As a result, this would produce new younger stars. So, basically, the concept done here is the mass and energy conservation. In order to create new species, the energy must come from another source.
The half life for C14 is 5730 years.
We assume that Carbon 14/ Carbon 12 ratio was steady for living organisms over time, the problem is actually telling us that

= 0.0725 =

ˣ
Take the natural logarithm and In on both sides.
ln(0.725) = ln

ˣ
= - 0.3216 = xln (

= -0.6931x.
So x = (-.3216) / (-0.6931) = 0.464
or
t/t₁/₂ = 0.464
So t = 0.464 x t₁/₂ = 0.464 * 5730 yrs = 2660 years.
Answer:
Explanation:
H2SO4 let S be x
2(1) + x + 4(-2) = 0
2 + x - 8 = 0
x - 6 = 0
x = 6
For H2S7O8 let S be x
2(1) + 7(x) + 8(-2) = 0
2 + 7x - 16 = 0
7x - 14 = 0
7x = 14
x = 14/7
x = 2
:- H2SO4 as the larger percentage
i believe the answer is...
Atoms of isotopes of an element have different numbers of protons.
