Answer:
The advantage of the compound light microscope over the dissecting microscope is the magnification power of the telescope. Compound light microscope magnifies from 40x up to 1,000x while dissecting microscope magnifies up to 40 x only. In this regard, more magnification power is advantageous to view smaller objects.
The electrical forces between the particles would decrease -q-q.
Hope this helps!!!:D
Answer:
Because you can see the stars everynight pretty much, but the planets you need a telescope for. Plus, the planets are moving everynight making night and day so they all move! :)

Answer:
Uranium can be isolated from its ores by dissolving it as UO 2(NO3)2, then separating it as solid UO2(C2O4)∙3H2O.
Answer:
292.5 g
Explanation:
<em>We know the formula:</em>
No of moles = Mass ÷ Mr of the Compound
<em>We need to find the mass, so make Mass as the subject of the formula.</em>
Mass = No. of moles × Mr of the Compound
<em>We know the no. of moles, as per given in question which is 5 moles.</em>
<em>Find the Mr of NaCl</em>
<em>Mass of Na = 23</em>
Mass of Cl =35.5
Mr of NaCl = 23 + 35.5 = 58.5
<em>Fill in the values in the formula.</em>
Mass = 5 moles × 58.5
Mass = <u>292.5 g</u>
