There are 3.2664292991356043 moles of MgCl2
C - concentration: 3.0M
n - number of moles: 1.50 moles
V - volume: ???
____________
C = n/V
V = n/C
V = 1.5/3
V = 0,5 L = 500 mL

This is true because the water would have gravitational potential energy that is caused by the water being held back by the dam and the water wanting to flow down.
This can be converted into kinetic energy when given the chance to, such as having a turbine on the dam.
Hope this helps! :)
Answer:
. B. The boxes must minimize thermal energy transfer to prevent thermal energy from transferring into the boxes.
Explanation:
If a box is to remain cool, energy transfer into the box must be minimized and energy transfer out of the box must be maximized.
This implies that only a minimal amount of thermal energy can transfer into the box while the box looses heat rapidly. If a box is this designed, it is likely to remain cool.
Answer:
E
Explanation:
A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap
