In is a lot easier because it uses 10s.

The metric system is broken down into smaller measurements it's also based on 10. It's easier for us humans and scientists.

Hope I helped! :)

Answer:

$SO_{3}^{2-}(aq.)+2OH^{-}(aq.)\rightarrow SO_{4}^{2-}(aq.)+H_{2}O(l)+2e^{-}$

Explanation:

The given reaction is an example of oxidation reaction. The step-by-step balancing procedure has been shown below:

Chemical equation: $SO_{3}^{2-}(aq.)\rightarrow SO_{4}^{2-}(aq.)$

Balance H and O in basic medium: $SO_{3}^{2-}(aq.)+2OH^{-}(aq.)\rightarrow SO_{4}^{2-}(aq.)+H_{2}O(l)$

Balance charge: $SO_{3}^{2-}(aq.)+2OH^{-}(aq.)\rightarrow SO_{4}^{2-}(aq.)+H_{2}O(l)+2e^{-}$

Balanced chemical equation:

$SO_{3}^{2-}(aq.)+2OH^{-}(aq.)\rightarrow SO_{4}^{2-}(aq.)+H_{2}O(l)+2e^{-}$

Which of the following is the best definition of a scientific theory? A predicted experimental outcome A mathematical model (an

Mkey [24]

Answer:

A well tested explanation of a natural phenomenon

Explanation:

A scientific theory is an explanation of a natural phenomenon which has been drawn from a well tested observation.

Theories are products of repeated scientific experiments. When a hypothesis otherwise known as a "scientific guess" survives a lot of scrutiny, we can elevate it to the status of a theory. Most theories starts off from simple observations. These observations can further spark series of experiments in such a field and a scientific guess proposed. Further testing and experimenting would now lead to a theory.

Find ∆G for a cell whose potential is +0.24 V with 4 moles of electrons exchanged.

Setler [38]

We need to use the following formula
Δ $G= -nF E_{cell}$

$E_{cell}= 0.24V$
n= 4 moles
F= constant= 96500C/mol

let's plug in the values.

ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ

For average speed, we divide the total distance covered by the total time taken.

After doing that, you will see that Jane has the lowest average speed.
