Calculate the volume of 3.0 mol HCl required to react completely with 10.0g of Na2CO3. Im confused about the "volume". What do they mean ? Do I have to find the mass of HCl then convert it into a volume?

then we have y = 0.5gt^2 and when i did it for both the Earth and the Moon, i got two really weird answers that aren't part of any of the choices..

so the initial velocity is 0m/s..

oh yeah whoops, wrong formula.. i tried using y = v0*t - 0.5gt^2 sorry my bad

The moon's gravity is about one sixth of the Earth's. (Basically, one sixth of 9.80m/s^2). If two objects were dropped at the same height on the Earth and on the Moon, the time it would take for the object to reach the surface of the moon compared to the Earth is... a) 6 b) 36 c) Square root...

Alright, I'll take that into consideration. Thanks a lot again! :) Really helped!

I have no idea. I believe it's displacement, if I'm not mistaken. My teacher and the textbook is really vague and not clear at all :(

Thanks for the help, but it's two problems in my book, and those are the exact words. So I don't know.
