Penny says that dust particles in space cannot be pulled together by the force of gravity because dust particles have very little mass. Ella says that as long as dust particles have mass at all, the force of gravity can pull dust particles toward each other. Which claim identifies who has the better argument and explains the reasoning? btw add me on discord FlickTC#8144

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
