<u>Answer</u>:
Final velocity: 1200 m/s
<u>Explanation</u>:
Formula:
<u>Where</u>:
a = average acceleration
v = final velocity
vo = starting velocity
t = elapsed time
<em>Here the final velocity is unknown which we have to find. The initial is 0 m/s</em>
<em>as it was at rest. The time taken: 150 seconds. Acceleration given 8.0 m/s²</em>
using the formula:
m/s
Answer:
B. 26.00 g Fe
Atomic mass of Fe (Iron) is 55.845g
Answer:
Explanation:
Hello,
In this case, since the pH defines the concentration of hydrogen:
And the percent ionization is:
We compute the concentration of the acid, HA:
Thus, the Ka is:
So the pKa is:
