Use the following equation for the decomposition of mercury(II) oxide.
2HgO(s) → 2Hg() + O2(g)
In a certain reaction 3.75 g of HgO is decomposed, producing 3.21 g
of Hg.
What is the theoretical yield of Hg?
a 3.21 g Hg
b 3.47 g Hg
C4.05 g Hg
d 1.74 g Hg

12. complete each of the following word equations for synthesis reactions. a. sodium + oxygen -> b. magnesium + fluorine -> 13. complete and balance the equations for the decomposition reactions. a. hgo -> [with the triangle heat symbol above the arrow] b. h2o(l) -> [with "electricity" written above the arrow]

Why doesn't heat added to water make the tempature rise above 100c

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
