An engineer is designing a device to reduce the chance of collisions between cars. They have selected a solution and built a prototype. What is the next step? test the prototype on model cars in a lab

compare the performance of the device to that of similar devices

communicate the results by telling everyone about the prototype

research existing data on accidents involving cars

Melissa is interested in her family tree and how her family has changed over its many generations. melissa probably more closely resembles

Calculate the molarity of each of the following solutions. part a) 0.12 mol of lino3 in 5.5 l of solution part b) 60.7 g c2h6o in 2.48 l of solution part c) 14.2 mg ki in 100 ml of solution

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.
