CCC Patterns As you move across a period in the periodic table from left to right, the number of electrons in the atoms’ shells increases. Based on the pattern you observed in Question 5, do you see a trend relating the melting point of a transition metal in Periods 4 and 5 to the number of electrons each atom has? Explain.

Isopropyl alcohol, (ch3)2choh, is a common solvent. determine the percent by mass of hydrogen in isopropyl alcohol. a) 6.71% h b) 13.4% h c) 25.0% h d) 53.3% h

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution

How many atomic mass units are equal to 1.672×10−24 g of protons?
