Suppose you carry out a titration involving 1.90 molar CsOH and an unknown concentration of HI. To bring the reaction to its end point, you add 9.9 millimeters of CsOH to 25.0 milliliters of HI. Now you know that you have a A.) 0.21 M, B.) 0.75 M, C.) 2.1 M, D.) 4.8 M solution of HI.

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic

The number at the end of an isotope’s name is the number.

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
