3)The rate of the forward reaction is equal to the rate of the reverse reaction
Answer:
H3PO4 is the formula for hydrophosphoric acid
The main formula is as follow is explained in the attached file (please look at the examples)
the 1,3- butadiene is h2c=ch-ch=ch2, so we have
sp² sp² sp² sp²
h2c = ch - ch = ch2
<span>the hybridization of the carbon atoms is </span>sp² : trigonal planar
Answer:
6.25%
Explanation:
Given data:
Half life of lutetium-117 = 6.75 days
Percentage remaining after 27 days = ?
Solution;
Number of half lives = Time elapsed / half life
Number of half lives = 27 days / 6.75 days
Number of half lives = 4
At time zero = 100%
At first half life = 100%/2 = 50%
At second half life = 50%/2 = 25%
At 3rd half life = 25%/2 = 12.5%
At 4th half life = 12.5%/2 = 6.25%
