Answer:
During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers.

The balanced equation is
4NO2(g)+O2(g)+2H2O(l) ==> 4HNO3(aq)
Determine the molar mass of NO2 and HNO3.
Atomic weight nitrogen = 14.0067
Atomic weight hydrogen = 1.00794
Atomic weight oxygen = 15.999
Molar mass NO2 = 14.0067 + 2 * 15.999 = 46.0047 g/mol
Molar mass HNO3 = 1.00794 + 14.0067 + 3 * 15.999 = 63.01164 g/mol
moles NO2 = 14000 g / 46.0047 = 304.3167329 mol
Looking at the balanced equation
4NO2(g)+O2(g)+2H2O(l) ==> 4HNO3(aq)
it's obvious that each mole of NO2 will produce one mole of HNO3. So we should have 304.3167329 moles worth. Just multiply by the molar mass.
304.3167329 mol * 63.01164 g/mol = 19175.49642 g = 19.17549642 kg
Since our data only has 2 significant figures, round to 2 figures, giving 19 kg.</span>
Paleobotany is the study of plant fossils and remains. This can help us understand how plants lived long ago and how they were like.
Hope this helps ya!
