Answer:
41 inches
Explanation:
There is 12 inches in 1 foot so times 12 and 3. Thats 36 so now do 36 + 5 that =41.
Half life means is the amount of time only half the uranium is left. So after 68.9 years only 150/2 = 75 g is left. Another 68.9 years go by and then 75/2 = 37.5 g remains. See the pattern here?
then you can divide 250 by 68.9 to see how many times it's halved or just write the equation:
A = 150(0.5)^(t/68.9)
t is 250 years, A is amount left
A = 150(0.5)^(3.63)
A = 12.13 g
<u>Answer:</u> The net acid-base reaction of the anion formed and water is written below.
<u>Explanation:</u>
Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.
The chemical equation for the ionization of NaClO follows:
![NaClO(s)\rightarrow Na^+(aq.)+ClO^-(aq.)](https://tex.z-dn.net/?f=NaClO%28s%29%5Crightarrow%20Na%5E%2B%28aq.%29%2BClO%5E-%28aq.%29)
Now, the anion formed which is
reacts with water to form conjugate acid.
The chemical equation for the reaction of anion with water follows:
![ClO^-(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HClO(aq.)](https://tex.z-dn.net/?f=ClO%5E-%28aq.%29%2BH_2O%28l%29%5Crightarrow%20OH%5E-%28aq.%29%2BHClO%28aq.%29)
Hence, the net acid-base reaction of the anion formed and water is written above.
There are about 2.2 pounds per Kg. therefore, .25 lbs, or 1/4 lbs is about .113 kg. of butter
there are about 1000 g per kg, so .113×1000 = 113 grams of butter.
Finally, there are 1000 mg. in every gram, so 113 ×1000= 113,000 mg of butter.
The two most abundant are coal and forests
