18. What is the theoretical yield of water when 133.435g of hydrazine reacts with 292.625g of hydrogen peroxide? N, H, 0 + 2 H10, 0 · N, (g) + 4H,0 (g)

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.

And a) oxygen i believe

A, it is falling action my have a good day

Product should she record in last row of the table

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
