Answer:
The volume of the neon gas is 17.07 L.
Explanation:
The ideal gas equation describes the relationship among the four variables P, V, T, and n. An ideal gas<u> is a hypothetical gas whose pressure-volume-temperature behavior can be completely accounted for by the ideal gas equation</u>.
In order to calculate the volume, first we need to convert the grams of neon to moles:
28.18 g Ne ------ 1 mol Ne
5.0 g Ne---------- <u>x= 0.25 mol Ne</u>
Now, using the ideal gas equation we calculate the volume:
V= 17.07 L
Answer:
When a liquid releases enough energy, the liquid will freeze and turn into a solid. Phase changes are what causes one state of matter to turn into another. ... Phase changes occur because of changes in the amount of kinetic energy obtained by the particles that make up a substance. Kinetic energy is the energy of movement.
Explanation:
<em><u>Answer:</u></em>
Potassium.
<u><em>Explanation:</em></u>
Therefore, the answer is Potassium. You might think, that because we were talking about Argon as well, the answer is both of them, but no. Everything starts with Potassium but it decays into Argon during the process.
In order to find the answer, use an ICE chart:
Ca(IO3)2...Ca2+......IO3-
<span>some.......0..........0 </span>
<span>less.......+x......+2x </span>
<span>less........x.........2x
</span>
<span>Ca(IO₃)₂ ⇄ Ca⁺² + 2 IO⁻³
</span>
K sp = [Ca⁺²][IO₃⁻]²
K sp = (x) (2 x)² = 4 x³
7.1 x 10⁻⁷ = 4 x³
<span>x = molar solubility = 5.6 x 10</span>⁻³ M
The answer is 5.6 x 10 ^ 3 M. (molar solubility)
