Answer:
The lithosphere is broken into separate sections called plates. The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion, driven by convection currents in the mantle is plate tectonics.
Answer:
x = 100 * 1.1897 = 118.97 %, which is > 100 meaning that all of the HClO2 dissociates
Explanation:
Recall that , depression present in freezing point is calculated with the formulae = solute particles Molarity x KF
0.3473 = m * 1.86
Solving, m = 0.187 m
Moles of HClO2 = mass / molar mass = 5.85 / 68.5 = 0.0854 mol
Molality = moles / mass of water in kg = 0.0854 / 1 = 0.0854 m
Initial molality
Assuming that a % x of the solute dissociates, we have the ICE table:
HClO2 H+ + ClO2-
initial concentration: 0.0854 0 0
final concentration: 0.0854(1-x/100) 0.0854x/100 0.0854x / 100
We see that sum of molality of equilibrium mixture = freezing point molality
0.0854( 1 - x/100 + x/100 + x/100) = 0.187
2.1897 = 1 + x / 100
x = 100 * 1.1897 = 118.97 %, which is > 100 meaning that all of the HClO2 dissociates
The answer is AlCl3, it’s 133.34g/mol
Answer:
I think that temperature will be cut in half.
When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!
CH4 and PH3 are both covalent since they are composed both of non-metals.
<span>
CH4 is non- polar because of </span> London forces and<span> has a geometry of tetrahedral PH3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (IMF) . Since PH3 is polar, it has a stronger IMF </span>
