What change did the iv cause
<span>The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together and the uniformity of their composition. Ahomogeneous mixture is a mixture where the components that make up the mixtureare uniformly distributed throughout the mixture.</span>
Answer:
Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.
Explanation:
The name of noble or inert gas is due to the lack of reactivity with other elements. This is due to its electronic configuration, because its outermost shell or valence shell is always complete, without the need to share, give or receive electrons forming bonds. That is, its outer layer is so stable that the element tends not to react with others except in very specific cases.
These exceptions generally involve the heavier noble gases, such as xenon or radon, capable of forming compounds with fluorine and oxygen. This is because the heavier noble gases have more electron shells than the lighter ones. This characteristic causes the outermost electrons to experience a "shielding" effect due to the action of the inner electrons, and they can then be ionized more easily, since the attraction they receive from the positive charges of the nucleus is weaker. That makes the ionization energy low enough to form stable compounds with more electronegative elements, such as fluorine and oxygen.

Answer:
2000 mL
Explanation:
We have the following data:
Initial volume: V₁ = 1000 mL
Initial temperature: T₁ = -86°C + 273 = 187 K
Final temperature: T₂= 101°C + 273 = 374 K
According to Charles' law, as the temperature of a gas is increased at constant pressure, the volume is increased. That is expressed mathematically as:
V₁/T₁ = V₂/T₂
Thus, we calculate the final volume V₂ as follows:
V₂ = V₁/T₁ x T₂ = (1000 mL)/187 K x 374 K = 2000 mL
Therefore, the final volume is 2000 mL.
