Lamar is testing several solutions to identify which ones are acids, which ones are bases, and which one is water. He hypothesizes that solution number 3 is water. For Lamar’s hypothesis to be supported by his data, which of the following pH values must solution number 3 be near? SC.8.N.1.3 A
1.0

B
9.0

C
7.0

D
12.0

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

Why is no-till farming more sustainable than many traditional methods of farming

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not
