Answer:
A piece of gold foil was hit with alpha particles, which have a positive charge. Most alpha particles went right through. This showed that the gold atoms were mostly empty space. Some particles had their paths bent at large angles. A few even bounced backward. The only way this would happen was if the atom had a small, heavy region of positive charge inside it.
c) positively charged and relatively small.

The right answer is the fat will become richer in energy (provides more ATPs) and more hydrophobic and less volatil.
The length of the carbon chain allows a classification of fatty acids in 4 categories: volatile fatty acids, with 2, 3 or 4 carbon atoms, short chain fatty acids which have between 6 and 10 carbon atoms, fatty acids medium chain, with 12 to 14 carbon atoms and long chain fatty acids, with 16 or more than 16 carbon atoms.
Answer:
a) 15.55
b) 0.55
Explanation:
you can use geram of I2 instead of geram of NI3 in (b)
it gives the same ans
In general when you heat up a liquid such as water its volume "increases" as the heat energy causes the water molecules to move leading to more space between molecules causing it to occupy a larger volume.
hope that helps
