Answer:
Becuase CH30 has weaker inter-molecular forces
Explanation:
Becuase its intermolecular forces are weaker the particals will seperate more easilyl.
Answer:
copper wire, metal nail, battery
Explanation:
To create an electromagnet, the material to be magnetized (such as a metal nail) is placed inside a solenoid, the ends of the coils are connected to a circuit that includes a battery.
Current is allowed to flow for a few seconds and then cut off. The polarity of the magnet depends on the direction of flow of current in the solenoid.
Answer:
Actual yield: 86.5 grams.
Explanation:
How many moles of formula units in 95 grams of calcium carbonate 
?
Refer to a modern periodic table for relative atomic mass data:
- Ca: 40.078;
- C: 12.011;
- O: 15.999.
Formula mass of :
.
.
How many moles of 
will be produced?
The coefficient in front of in the chemical equation is the same as that in front of . That is:
.
.
What's the theoretical yield of calcium chloride? In other words, what's the mass of 
of ?
Again, refer to a periodic table for relative atomic data:
.
.
What's the actual yield of calcium chloride?
.
.
Answer:
D)
Explanation:
because they have completely filled and stable electron shells. Using you periodic table, it can show you that the noble gases are furthest to the right and explain the way outer shells of electrons work.
have a good day :)
Answer:
In the explanation
Explanation:
Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.
Convergent: When two plates are moving towards each other.
If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.
If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.
Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.
Hope this helps!
