AI Thread Summary
The discussion revolves around writing and balancing chemical equations, specifically for the reaction between calcium and sodium. The initial attempt at the word equation suggests "Calcium + Sodium -> Tricalcium disodium," but there is confusion regarding the correct naming and balancing of the equation. It is pointed out that the initial equation is unbalanced, with a discrepancy in the number of calcium atoms on each side. The conversation shifts to another reaction involving calcium and oxygen, where the user successfully balances the equation as 2Ca + O2 -> 2CaO. Overall, the thread highlights common challenges in understanding and balancing chemical equations.

Homework Statement


Ok I am absolutely terrible at chemistry and a friend asked me to help her with this and she has no one else so i figured I would come here.

Write the word equation and balanced equation:

Ca(s) + Na2(g) -> Ca3Na2(s)

The Attempt at a Solution



Would the word equation just be Calcium + Sodium -> Tricalcium disodium? what about the balanced equation?

6Ca + 2Na2 -> Ca3Na2(s)

I have a feeling I'm doing this completely wrong lol.

I'm not going to touch the "word equation." I wonder whether the compound is really called Tricalcium disodium...sounds funny.

You have 6 calcium atoms on the left hand side and only 3 on the right hand side. How is that balanced?
 
Perhaps something like "n moles of solid calcium plus ... yields ... " ?
 
You sure it is not nitrogen instead of sodium?

That balances it.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
