Answer:
Ionic bonds are formed between metals and nonmetals. The compatability of the metals and nonmetals is what makes them have a neutral charge as they cancel each other.
Eg: Using sodium chloride.
Na+ + Cl- > a neutral compound of NaCl without charges.
The Star gets stretched and torn apart by the gravitational pull of the black whole, stellar material gets compressed as it is pulled in, this is called, stellar tidal disruption
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.

Explanation:
Due to the fact that the mentos are dense, they sink to the bottom of the bottle which gives the diet coke its explosion.
