Draw the qualitative results one would obtain from a hypothetical 2D SDS-PAGE electrophoresis of a mixture containing three protein samples: 80 kDa protein containing lysine residues (pI 8.4), a 100 kDa protein containing mostly alanine residues (pI 5.1), and a 30 kDa protein containing mostly aspartic acid residues (pI 3.7). Clearly label the axes (isoelectric focusing from low to high pI and SDS-PAGE from low to high MW) and which spots correspond to which protein. Do not use numbers.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?

Which type of intermolecular attractions holds ammonia molecules together with other ammonia molecules?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table?
