Answer:
3
Explanation:
Lt= Loe^(-kt)
Data:
Lo = 10 mg/mL
Assume k = 0.23/da
1. Calculate L5
L5 = 10e^(-5×0.23) = 10e^-1.15 = 10 × 0.317 = 3.17 mg/mL
2. Calculate the dilution factor
You expect to find L5 to be about 3
You want L5 to be about 1.
You should use a dilute your sample by a factor of 3.
P = 3
Answer:
a base
Explanation:
first convert the pOH to pH, that way it will
be easy to decide.
formula:pOH+pH=14
pH=14-4.3=9.7
high pH tells us it's a base
Answer:
12: This is decomposition because nitrogen triiodide is breaking apart.
13: This is double displacement because the elements in the compounds are "switching".
14: This is synthesis because the water and carbon dioxide are combining.
15: This is also synthesis because the hydrogen and oxygen are combining.
16: This is single displacement because the sodium is "switching" the element it's bonding with.
Explanation:
Micro - 1/1,000,000 of the base unit
Kilo - 1,000 times the base unit
Milli - 1/1000 of the base unit
Centi - 1/100 of the base unit
Mega - 1,000,000 times the base unit
Nano - 1/1,000,000,000 of the base unit
