Answer:
≈ 0.10M
Explanation:
[A]o = 0.27M
Rate constant, k = 0.75 s−1
[A] = ?
time, t = 1.3
Integrated formular for a first order reaction is given as;
ln[A] = ln[A]o − kt
ln[A] = ln(0.27) - 0.75(1.3)
ln[A] = -1.309 - 0.975
ln[A] = -2.284
[A] = 0.1019M ≈ 0.10M
Answer:
1×
Explanation:
To solve this, you will need to do multiple steps.
Firstly, you will have to convert to pOH from pH, which is done by simply subtracting 14-10 to get a pOH of 4.
Then, use the following formula to calculate the [OH-} concentration:
[OH-]= 
When converted to Scientific Notation<u>,</u> you get a resulting answer of
<u>1×</u><u>.</u>
Answer:
C) 8
Explanation:
Total number of carbon atoms = 3
Number of single bonds = 3
So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.
Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.
<u>Total - 8</u>
C. On the left side .. what the chemical uses is always on the left and what it produces is always on the right.
The reaction is missing the Zn(s) in the reactants. The stoichiometry of the copper/zinc is 1 mole to 1 mole
