For a first order reaction, the half life is inversely proportional to the rate constant.
The formula is
half life = ln(2)/k = 0.693/k
where k is the rate constant
t = 5.50 minutes
k = ln(2)/5.50 = 0.126 min^-1
Your rate constant is 0.126 min^-1.
Answer:
Brass
Explanation:
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties.
C.
Water is polar because one side of the molecule is positive and the other is negative.
