What dose buoyancy have to do with jumping?

1 answer:

8 0

Buoyancy is a condition in which a physical body's average density is equal to the density of the fluid in which it is immersed.

The buoyancy offsets the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it's less). An object that has neutral buoyancy will neither sink nor rise.

Hope this helps! xx

4Fe (s) + 3 O2 (g) → 2 Fe2O3 (s)

Novay_Z [31]

Explanation:

The number acquired by an element after the lose or gain of an electron is called oxidation number.

For example, $4Fe(s) + 3O_{2}(g) \rightarrow 2Fe_{2}O_{3}(s)$

Here, oxidation number of Fe(s) is 0 and Fe in $Fe_{2}O_{3}$ is +3.

Oxidation number of O in $O_{2}(g)$ is 0 as it is present in its elemental state.

The oxidation number of O in $Fe_{2}O_{3}$ is calculated as follows.

$2(3) + 3x = 0\\6 + 3x = 0\\x = \frac{-6}{3}\\= -2$

Hence, oxidation number of O in $Fe_{2}O_{3}$ is -2.

The loss of electrons by an element or substance is called oxidation. Here, electrons are being lost by Fe(s) as an increase in oxidation state is occurring. So, Fe(s) is oxidized.

The gain of electrons by an element or substance is called reduction. Here, electrons are being added to $O_{2}$ as a decrease in its oxidation state is occurring. So, $O_{2}$ is reduced.

An element or compound which is being reduced is called oxidizing agent. Here, $O_{2}$ is the oxidizing agent.

An element or compound which is being oxidized is called reducing agent. Here, Fe(s) is the reducing agent.

If an acid is combined with a base of equal strength, the result will most likely be. a. a neutral solution b. a stronger acid c

Lady_Fox [76]

If the strength of the base and acid is EXACTLY the same/equal, the result would be: A. a neutral solution
That is why we used a base based medicine to treat our acid reflux because it will bring back the condition of our stomach into its neutral state

hope this helps
