Answer:
SO has about 0.52 moles, while NO has about 0.83 moles
Explanation:
To calculate the number of moles of a certain molecule, you first need to figure out that molecule's molar mass. For SO, the molar mass is the mass of sulfur combined with the mass of oxygen. 16 + 32=48. For NO, you do a similar thing but with nitrogen. 16+14=30. From here, you can simply divide. 25 grams divided by SO's molar mass of 48 yields about 0.52 moles, while for NO there is about 0.83 moles. Hope this helps!

Answer:
Chemical energies
Explanation:
We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy - this is one way of making electricity, see Electricity for more information.
Answer:
c
Explanation:
you don't think of particles as dense and less dense
dust particles containvenergy but won't release it unless acted upon a force
gas molecules move freely and collide with dust particles which is correct
