Answer:
A solution of NaOH has concentration 1.2M. Calculate the mass of NaOH in g/dm3 in this solution. = 1.2x 40x 1 = 48 g 3.
Answer:
boundary interactions: areas where plates move away from each other forming mid-ocean ridges or rift valleys.
divergent boundaries: this happens when 2 tectonic plates move away from each other. along these boundaries earthquakes and magma are common as they are rise from the mantle to the sruface making new oceanic crust.
convergent boundaries: this is an area on earth where 2 or more lithospheric plates collide. they will slide under one another creating a subduction.
transform boundaries: transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.
Explanation:
lithosperic means the solid outer part of the earth.
hope this helps and good luck! :) <3
Answer: D
Explanation:
London forces become stronger as the atom in question becomes larger, and to a smaller degree for large molecules. [4] This is due to the increased polarizability of molecules with larger, more dispersed electron clouds. The polarizability is a measure of ease with which electrons can be redistributed; a large polarizability implies that the electrons are more easily redistributed. This trend is exemplified by the halogens (from smallest to largest: F 2 , Cl2 , Br 2 , I 2 ). The same increase of dispersive attraction occurs within and between organic molecules in the order RF<RCL<RBr<RI, or with other more polarizable heteroatoms. [5] Fluorine and chlorine are
gases at room temperature, bromine is a liquid, and iodine is a solid. The London forces are thought to be arise from the motion of electrons.
MgS2o3 weights (24.305) + 3(16) grams pre mole so if you divide 181 g by that number you will have the number of moles. Grams*(moles/grams)=moles
