Inference
Explanation:
No 10.
in order to prove that Mary Mellon was in fact infected by typhoid proper experiments needs to be carried out.
No. 11
inference means an assumption due to the situation.
This is an incomplete question, here is a complete question.
A certain first-order reaction has a rate constant of 5.50 × 10⁻³ s⁻¹. How long will it take for the reactant concentration to drop to 1/8 of its initial value?
Answer : The time taken will be, 378.1 s
Explanation :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = ?
a = let initial amount of the reactant = x
a - x = amount left after decay process =
Now put all the given values in above equation, we get
Thus, the time taken will be, 378.1 s
it would be b hope i helped
Answer:
Higher pressure, is the right answer.
Explanation:
The A will have a higher pressure. Since we have given the volume and temperature is same in both containers A and B. Below is the calculation for proof that shows which container has the higher pressure while keeping the volume and temperature the same.
Therefore, the container “A” will have higher pressure.
