Answer:
7 moles
Explanation:
The molecular formula of sodium sulfide is Na_2S
One molecule of Sodium sulfide has 2 atoms of sodium and one atom of sulfur
1 mole of Sodium sulfide has 2 moles of sodium and one mole of sulfur
so 3.5 moles of sodium sulfide will have 2× 3.5 moles of sodium atoms
i.e 2×3.5= 7 moles of sodium atom
Light Spectrum:
Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio
I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
Plants can adapt to their environment for example algae is soft and can survive being moved or broken this is perfect for living on top of water were animals often swim and shake the surface.
Answer : The mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.
Explanation :
As we are given that, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide. Now we have to determine the mass of nitrous oxide formed from 85.20 g of nitrogen.
As, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide
So, 85.20 g of nitrogen is present in
of nitrous oxide
Thus, the mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.
