Henry law:
P = KC
P = solvent vapour pressure
K = Henry constant
C = conc of solute
So, 0.2 = 773 C
so, C = 0.2 / 773 = 2.5 x 10^{-4} molal
Answer: oxygen
Explanation: as you go across period on the periodic table, the elements get larger. Their atomic masses also increase meaning it gets heavier and thus larger.
No. When water first begins to cool down, it contracts. However, as it gets colder and eventually freezes, it begins to expand.
You can test this by freezing water in a water bottle: when you take it out of the freezer, the cap might have popped off or cracks may have formed in the sides of the bottle.
Answer: Water expands when frozen, not contracts.
<h2>Decomposition</h2>
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.
Since there is only one reactant and it is broken into smaller components,
it is not a synthesis reaction.
A decomposition reaction is a type of chemical reaction in which one reactant yields two or more products.
Since in our question,there is one reactant and it is broken to yield two products,it is a decomposition reaction.
A) <span>he smallest dipole–dipole forces have xenon (Xe), because xenon is a noble gas and have stable electron configuration and do not form dipole.
b) t</span><span>he largest hydrogen bond forces have HF because hydrogen bonds are formed between hydrogen and F, O and N.
</span>c) the largest dispersion forces have CH₃Cl because he has strongest <span>induced temporary dipoles.</span>
