Answer:
The final volume of NaOH solution is 30ml
Explanation:
We all know that
V1S1 = V2S2
or V1= V2S2÷S1
or V1= V2×S2×1/S1
or V1=100×0.15×1/0.50
V1= 30
∴30 ml NaOH solution is required to prepare 0.15 M from 100ml 0.50 M NaOH solution.
Explanation:
If you take the ideal gas law of PV = nRT and modify it to
P*molar mass = density*RT
(745/760)*M = 1.2*0.08206*293
Solve for M = molar mass.
For reaction
2 A + B ------------> 2 C
Rate = K [ A ]² [ B ]
<span> the order with respect to A is 2 and the order overall is 3.

If bubbles aren't a for sure way of knowing a chemical reaction I don't know what is. But being for real, it is a chemical change because the bubbles are releasing carbon dioxide meaning it turned into a product from a reaction with outside forces.
