1st half-life: 100%/2 = 50%
2nd half-life: 50%/2 = 25% + 50% (from first half-life)
3rd half-life: 25%/2 = 12.5% + 75% (from first and second half-lives

<h2>YES</h2>
Explanation:
Coyotes and oak trees are multicellular organisms and multicellular organisms reproduce asexually and sexually.
Many multicellular lower plants give off asexual spores, either aerial or motile and aquatic (zoospores), which may be uninucleate or multinucleate.
The pH of the solution is 4.38.
<h3>What is the pH?</h3>
The first thing that we must do is to set up the ICE table for the reaction as shown;
Given that;
HA = 1.8 M
HA(aq) + H2O(l) ⇔ H3O^+(aq) + A^-(aq)
I 1.8 0 0
C - x +x +x
E 1.8 - x x x
K = [H3O^+] [A^-]/[HA]
9.55 × 10^−10 = x^2/0.0158 - x
9.55 × 10^−10(1.8 - x ) = x^2
1.719 * 10^-9 - 9.55 * 10^-10x = x^2
x^2 + 9.55 * 10^-10x - 1.719 * 10^-9 = 0
x=0.000041 M
pH = -log(0.000041 M)
pH = 4.38

12.0g x 1 mol / 63.546g = 0.188839581mol
<span>So, for every 1 mole, we have 6.022 x 10^23 of whatever we're measuring. This gives us a conversion factor of (1 mole / 6.022 x 10^23 atoms) or (6.022 x 10^23 atoms / 1 mole).
</span>
0.188839581 mol x (6.022 x 10^23 atoms) / 1 mol = 1.137191955 x 10^23
<span>Remember from before that we are limited to 3 significant figures. Since our calculations are complete, we can now round down to: 1.14 x 10^23 </span>
<span>That should be your answer!
Hope it helps!

Answer:
Living organisms need water to survive. Many scientists even believe that if any extra-terrestrial exists, water must be present in their environments. All oxygen-dependent organisms need water to aid in the respiration process. Some organisms, such as fish, can only breathe in water. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.
