Answer:
Plasma
Explanation:
Plasma is a state of matter that in some cases is a synonym of ionized gas. It consists of groups of ions (particles with a net charge) with some of their outer electrons removed.
How many electrons have been removed depends on the type of plasma, since the most energetic plasmas are completely free of orbiting electrons. This is the case of the interiors of the sun and other stars.
Volume decreases. The smaller it gets the higher the density
Answer:
An amide may be produced by reacting an acid chloride with ammonia.
<span>No, the battery does not need to be recharged.
The balanced reaction is:
NaOH + H2SO4 ==> Na2SO4 + H2O
So for each mole of H2SO4, one mole of NaOH is needed. So let's determine the number of moles of NaOH we used:
0.03126 L * 0.621 mol/L = 0.01941246 mol
So we now know that 0.01941246 moles of H2SO4 was present in the sample. And since molarity is defined as moles per liter, we can divide the number of moles we had by the number of liters to get molarity. So:
0.01941246 / 0.002 = 9.706 M.
This molarity is way too high to be reasonable. So let's do a sanity check on the original measured quantities. Our original sample is 2.00 ml and we titrated with 31.26 ml or 31.26/2 = 15.63 times as much base. So the molarity should be that value times the molarity of the base, which is 15.63 * 0.621 = 9.706 which matches the original calculated figure.
The conclusion is that the battery does not need to be recharged. If anything, it's over charged. Also, it's highly likely that this problem has a typo and that the figures given are incorrect. Please check your original problem before using this as your answer.</span>
<span> It showed that the atom contains a small dense nucleus. The reason why this can be concluded is that the experiment showed that alpha particles can for the most part pass right through the foil. This showed that the nucleus of the atom is very small and takes up a very small portion of the size of an atom since the nucleus is what would reflect the alpha particle. If atoms were not mostly empty space, the alpha particles would have been bounced back and the opposite of what was observed would have happened (all or at least the majority would be bounced back instead the majority getting through with only a small portion being reflected back).
I hope this helps. Let me know in the comments if anything is unclear.</span>
