Answer: Sulfur
Explanation: Sulfur has 16 protons, silicon has 14 protons, and gold has 79 protons.
Answer:
Explanation:
A solid, at a given temperature, has a definite volume
and shape which may be affected by changes in
temperature. Solids usually increase slightly in size
when heated (expansion) and usually
decrease in size if cooled (contraction).A liquid, at a given temperature, has a
fixed volume and will take up the shape of any
container into which it is poured. Like a solid, a
liquid’s volume is slightly affected by changes in
temperature.
A gas, at a given temperature, has neither a definite
shape nor a definite volume. It will take up the shape
of any container into which it is placed and will
spread out evenly within it. Unlike those of solids
and liquids, the volumes of gases are affected quite
markedly by changes in temperature.
Answer:
One mole of anything has 6.023 x 10^23 molecules.
That would mean 3.4moles of CO2 have 6.023x 10^23 times 3.0.
So that would be2.04782×10^24 molecules in 3.0 moles of C02.
Answer:
3.4moles
Explanation:
Given parameters:
Number of molecules = 2.04 x 10²⁴
Unknown: Number of moles
Solution
We use the concept of mole to solve this kind of problem.
A mole is the amount of substance that contains Avogadro's number of particle i.e 6.02 x 10²³ molecules
Solving
For elementary particles:
Number of moles = 
¹ molecules
Number of moles = 
Number of moles of H₂O = 0.34 x 10¹ = 3.4moles
