Answer:
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.

Answer:
0.47dm³
Explanation
Given parameters :
Molarity of NaCl = 6.67M
Number of moles = 3.12mol
Volume of NaCl =?
Volume of NaCl = number of moles/Molarity
Volume of NaCl = 3.12mol/6.67M
Volume of NaCl = 0.47dm³
Answer:
Water acutually has a higher boiling point because CO2 will turn into a gas form at a certain temp ( -78 C), so CO2 wouldn't really boil very long.
Hope this helps:)
The equation ΔHsoln = ΔH1+ΔH2+ΔH<span>3 means that either the solution is endothermic (</span>ΔH < 0, the resulting reaction is cold) or exothermic (ΔH>0, the resulting reaction is hot). The lattice energy can be solve through this equation,
<span>lattice energy = </span>ΔHsolvation - IMF - ΔHsoln<span>

Hello!
The anhydrous calcium chloride (CaCl₂) is a hygroscopic substance. That means that the substance has a very high affinity with water (H₂O).
Water vapor from the air reacts with CaCl₂ to form Hydrated complexes following this reaction:
CaCl₂ + nH₂O → CaCl₂*nH₂O
In this reaction, water vapor is consumed and removed from the air, lowering the humidity of the air inside the desiccator.
