<span>When you squeeze an air-filled balloon, you are decreasing its volume. Imagine a ball going at a constant speed between two walls that are 10 feet apart vs. 1 feet apart. You can imagine that when the walls are only 1 feet apart, the ball will hit the walls more times. Therefore, the answer is A. You are correct.</span>
Answer:
Heat of solution= - 63KJ/mole
Heat evolved = - 18.82KJ
Explanation:Heat of solution = Heat of solute + Heat of hydration
◇Hsoln = - ( - 7.3 × 10 ^ 2) + ( - 793 ) KJ / mol
◇H soln= - 63 KJ
Use enthalpy of solution equation to determine the enthalpy of solution for LiI
LiI ---> Li^ + + I^-
Molecular mass of LiI=133.85g
The chemical equation for the dissociation will be:
40gLiI (1molLiI)/133.85g LiI - 63KJ/1 mol LiI
18.82KJ
The heat was evolved because the value of enthalpy was negative
Explanation:
“The basic principle of mass spectrometry (MS) is to generate ions from either inorganic or organic compounds by any suitable method, to separate these ions by their mass-to-charge ratio (m/z) and to detect them qualitatively and quantitatively by their respective m/z and abundance
Answer:
Explanation:
Hello,
In this case, for the given equilibrium, we write the law of mass action:
Next, in terms of the change due to the reaction extent (ICE procedure):
Clearly, the initial concentration phosphorous pentachloride is 1 M (one mole per litre), therefore, since the equilibrium concentration is 0.2 M (same volume) we can compute :
Thus, we compute the equilibrium constant:
