Answer:
Mn= +3 charge
Explanation:
if you take what we know, and that would be the charge of oxygen, we know that oxygen has a 2- charge and there are 3 sets of O^2- so multiply the number of oxygen times the charge and you get 6-.
Next set up an equation as listed in the picture which will be 2(x)=6
and that is the charge of the Mn ion.
Answer:
C) surface tension
Explanation:
Surface tension is the stretching force on a liquid's surface film caused by bulk liquid particles attracting themselves in the surface layer, which minimises surface area of the liquid.
The surface tension water is high as the strong hydrogen bonds of the on the surface
pull the water molecules together. As such a water drop will tend to occupy the smallest area on the surface.
Water surface tension is 72 dynes/cm at 25°C . That means 72 dynes of force is required to break a water surface film of 1 cm long. Water surface tension varies inversely with temperature. Surface tension of water is as a result of water molecule's polar nature of the and hydrogen bonding.
It’s far away from us and there for that how the moons spin
Usually, the more something ionizes, the better it conducts electricity. NH3 is molecular. CH3OH is an alcohol and doesn't ionize well. I'd say MgCl2 was more ionizable than H2O2, just because it's less likely to cause metathesis.
