Answer:
Explanation:
mass of the reactant = mass of the product
15.31 + 1.50 = 16.81g
Answer:
metre measures length
kilogram measures mass
time is seconds
Explanation:
I have matched correctly. Just check SI units and there measures.
Answer:
-0.129V
Explanation:
The change in free energy is obtained from the given parameters after which the value is now applied to obtain the cell potential in volts from the formukar shown in the solution below.
Radioactive material obeys 1st order decay kinetics,
For 1st order reaction, we have
k =

where, k = rate constant of reaction
Given: Initial conc. 100, Final conc. = 6.25, t = 18.9 hours
∴ k =

= 0.1467 hours^(-1)
Now, for 1st order reactions: half life =

= 4.723 hours.
