The appropriate solutions to each question should be supplied separately to promote undistracted attention to fulfilling appropriate evaluation: they are provided below sequentially.Question 4# Answer A, B, C, D or E based upon faithful evaluation of given entries in the chart in responseQuestion 5# Again for this question, the answer should be filtered from Choices A-E, subject to control of stipulated treatments.Question 6# The problem requires calculations based on raw dataset to settle upon an answer between A-E. Question 7# Answers A-E envelope assimilated choices for balancing the given chemical equations sought from the enquiry.# The answers to items 4 through 7 entirely subject precepts defined in questions posted naturalistically influencing derivation of anticipated responses outlaid within pre-determined choices i.e. A-E.

Penjelasan

Four questions are found in the posted "Question". It includes multiple choice questions (MCQs) on chemical compounds, chemical properties, and chemical effects. Please understand that as the Question contains poor English, illegible sentences or complicated terminologies, this explanation solely focuses on providing a comprehensive breakdown of the queries posed. For example, Sol NiS is the name of water-solvable solution for the compound Nickel sulfide, also described as a gel or colloidal suspension.While fully interpreting some questions became challenging, other identifiable queries belonged to Chemistry. One request asked for the relative atomic mass (massa atom relatif) of an unidentified metal based on specific molecular proportions. Furthermore, it imposed asking about a reaction of several sets of chemical equations provided, including KMnO4 reacting with KNO2 in an acidic solution.Question 4This question highlights potential pairings from the given chart, including the Tyndall effect, absorption, electrophoresis, and coagulation.Question 5The question is based upon the options provided for the dispersion process and identification of specific colloidal solutions.Question 6The problemRequirements an unidentified metal's relative atomic mass based on experimental solute concentration derived freezing point (titik beku).Question 7The question deals with a redox reaction between KNO2, KMnO4, and H2SO4 within a solution and requests the user to fill in the missing reactant and product, communally by assessing missing oxidation numbers.
