How does a bannana flaot

2 answers:

6 0

A banana floats when put in water because bananas are less dense than water, meaning that things with a higher density naturally push it to the surface.
Root beer floats are a different matter, though ;-)
Hope that helped =)

1) 7.15 * 10^6

since the exponent of the scientific notation is positive, move 6 places to the right.

so, 7.15 * 10^6 = 7150000

2) 3.03 * 10^-8

Since the exponent of the scientific notation is negative, move the decimal point 8 places to the left.

so, 3.03 * 10^-8 = 0.0000000303

3) 4.9 * 10^-1

since the exponent of the scientific notation is negative, move 1 decimal place to the left.

so, 4.9 * 10^-1 = 0.49

4) 2.886 * 10^5

since the exponent of the scientific notation is positive, move 5 decimal places to the right.

so, 2.886 * 10^5 = 288600

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:

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