HClO, perchloric acid is a weak acid. Unlike strong acids like HCl or H2SO4 it not dissociate completely but partially such that an equilibrium exists between the dissociated ions and the undissociated acid. The equilibrium is as shown below:
HClO + H2O ↔ H3O⁺ + ClO⁻
Since HClO is a weak acid, the reverse reaction is favored over the forward reaction. Thus apart from water, HClO will be present in large amounts.
The largest group of organisms that is capable of interbreeding is Species.
Answer:
a) 65.74 ± 0.01
b) 60.009 ± 0.001
c) 66 ± 1
d) 65.750 ± 0.001
Explanation:
When reporting results, scientist usually specify a range of values that they expect this "true value" to fall within. The most common way to show this range of values is: measurement = best estimate ± uncertainty
Uncertainties are almost always quoted to one significant digit (example: ±0.05 s).
Wrong: 34.3 cm ± 4.3 cm
Correct: 34 cm ± 4 cm
Always round the experimental measurement or result to the same decimal place as the uncertainty.
Wrong: 1.237 s ± 0.1 s
Correct: 1.2 s ± 0.1 s
Therefore for to answer the question:
a) 65.74 ± 0.01
b) 60.009 ± 0.001
c) 66 ± 1
d) 65.750 ± 0.001
I hope you find this information useful and interesting! Good luck!
D is the answer so now we can understand
Answer:
benefits: can help reduce waste in land fills, and promotes reusability (turned into different products)
drawbacks: can be much more expensive to salvage than to just throw it in a landfill, and most of the time products cannot be recycled effectively due to its material.
