<u>Answer:</u> The half life of the reaction is 593.8 seconds
<u>Explanation:</u>
We are given:
Rate constant =
The formula for determining the unit of 'k' is:
where, n = order of reaction
The unit of concentration is, M or mole/L
The unit of time is, second or 's'
Evaluating the value of 'n' from above equation:
The reaction is zero order reaction.
The equation used to calculate half life for zero order kinetics:
where,
k = Rate constant =
= initial concentration = 1.90 mol/L
Putting values in above equation, we get:
Hence, the half life of the reaction is 593.8 seconds
Answer:
False
Explanation:
A liquid has a definite shape and takes on the volume of its container. A gas has both the shape and the volume of its container. The particles in a gas cannot be compressed into a smaller volume. Liquids tend to contract when heated.

The molality of the solution is 0.0833 m
calculation
molality=mass of the solute/mass of the solvent
= 25g/300 =0.0833m
C funnel because the funnel would have a large enough entrance to put a solid through
Answer:
The answer to your question is: 28°C
Explanation:
Data
mass = 10 g
T1 = 23°C
T2 = ?
Q = 209 joules
Formula
Q = mC(T2 - T1)
T2 = Q/mC + T1
T2 = 209/(10 x 4.182) + 23
T2 = 4.99 + 23
T2 = 27.99 ≈ 28°C
