Answer:
cation
Explanation:
An atom that has lost an election becomes a positively charged ion and it's called a<em> </em><em>cation</em>
Answer:
1.666
≈ 1.67 g/cm³
Explanation:
Mass = 200g
Length = 6cm
Width = 4cm
Height = 5cm
Density = Mass/ Volume
Volume = length×width×height
Density =
At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 39 mL.
<h3>What is Avogadro's law?</h3>
Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."
It is expressed as;
V₁/n₁ = V₂/n₂
Given the data in the question;
- Initial amount of gas n₁ = 5.4moles
- Initial volume v₁ = 34mL = 0.034L
- Final amount of gas n₁ = 6.2moles
We substitute our values into the expression above.
V₁/n₁ = V₂/n₂
V₁n₂ = V₂n₁
V₂ = V₁n₂ / n₁
V₂ = (0.034L × 6.2moles) / 5.4moles
V₂ = 0.2108molL / 5.4mol
V₂ = 0.039L
V₂ = 39 mL
Therefore, at constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 39 mL.

Answer:
The sample of lithium occupies the largest volume.
Explanation:
Given the densities for the four elements, we have the expression that shows the relationship between mass and Volume to express the density of an element.
For each element we have:
The problem says that all the samples have the same mass, so:
it means that m is a constant
Now, solving for the Volume in each element and with m as a constant, we have:
If we assume m = 1g, we find that:
So we can see that the sample of lithium occupies the largest volume with 1.88mL
Note that m only can take positive values, so if you change the value of m, always will be the lithium which occupies the largest volume.
