0.5927-g sample was dissolved, and the Ca2+ and Ba2+ ions present were precipitated as BaC2O4

.H2O and

CaC2O4

.H2O. The oxalates were then heated in a thermogravimetric apparatus leaving a residue that weighed

0.5127 g in the range of 320°C–400°C and 0.4362 g in the range of 580°C–620°C. Calculate the percentage Ca

and percentage Ba in the sample.​

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.
