Answer: C
Explanation:
Indicators are organic weak acids or bases with complicated structures.
The rate of evaporation is equal to rate of condensation in equilibrium......It means the evaporation rate becomes constant.....And thus equilibrium attained !!!
I suppose there are answer choices you forgot to list but in general
They should think of a question
They should form a hypothesis
Do research and test
Have an independent and dependent variable
Have repetitions and replications
If there’s answer choices put them in the comments and I’ll answer it
Answer:
The loaded ship will weigh more. Thus it will sink down farther in the water in order to displace that much more water so that it continues to float.
Answer:
The minimum amount of such material that should be shipped is 63.9 mg≅ 64 mg.
Explanation:
Given Data:
Half life=1.8 hours
Formula:
Half life=0.693/k
Where:
k is rate constant
k=0.693/1.8
k=0.385 hr^-1
Formula to find initial concentration:
Where:
A is final concentration
A_o is initial concentration
t is time
Taking exponential on both sides:
The minimum amount of such material that should be shipped is 63.9 mg≅ 64 mg.
