Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
Answer:
Energy is lost at several levels from the body of an organism. Two of the phenomenons through which energy is lost are
Conduction:
When a body is in contact with another body, energy is lost in the form of heat. For example, if we sleep on a cold floor, energy from our body would be lost to the floor in the form of heat,
Decomposition:
Energy is lost when cells in a body die and energy is required for decomposition also.
Answer: True.
Explanation: Energy is being removed from the substance as it changes state. As energy is added to the liquid, particles throughout the liquid move faster. Boiling. When particles move fast enough to break away from other particles, they evaporate and become gas.
There are the answers for ur problems
You can make a table with each sun/star and plot them by color/heat. I hope this helps!
