Without using a calculator, decide which would give a significantly smaller value than 2.71 x 10^-2, which would give a significantly larger value, or which would give essentially the same value. A. 2.71 x 10^-2 + 1.00 x 10^-6
B. 2.71 x 10^-2 - 1.00 x 10^-6
C 2.71 x 10^-2 x 1.00 x 10^-6
D. 2.71 x 10^-2 / 1.00 x 10^-6

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

Why is the structure of molecule important to its function?

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
