Answer:
the pressure exerted in pascals is 0.5 Pa
Explanation:
The computation of the pressure exerted in pascals is shown below:
As we know that
Pressure = force ÷ area
= 25 ÷ 50
= 0.5 Pa
Hence, the pressure exerted in pascals is 0.5 Pa
We simply applied the above formula so that the correct pressure could come
The coefficient in a chemical formula represents the amount of each chemical present. The amount of a substance is measured in moles.
Answer:
k+
Ba2+

K+
S2-
you may think that if it has a + it would be bigger, but it is actually the opposite.
Answer:
Fe is just the shortened version of Iron whereas Fe2+ is a positive ion,cation to be more specific
The name and chemical symbol of the elements are
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
<h3>What are chemical symbols?</h3>
Chemical symbols are which are used to represent the elements in the periodic table.
The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.
The name and symbol of the given elements are as follows:
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.
