Statement 1: Cellular respiration allows orn=ganisms to liberate the energy stored in the chemical bonds ofglucose.Statement 2: C6H12O6 + 6 026 CO2 + 6H2O + 36 ATP; In this reaction, glucose is reduced and oxygen isoxidized.28. Statement 1: The reaction of a metal with either an acid or a metal salt is called a displacement reactionbecause the ion in the solution is replaced through the reduction of an element.Statement 2: When metals undergo displacement reactions with acids, salts and hydrogen gas is produced.29. Statement 1: The oxidation number of Hydrogen is -1 when bonded to nonmetals and +1 when bonded tometals.Statement 2: The oxidation number of Fluorine is -1 in all compounds.30. Statement 1: Alkali and alkali earth metals are the least easily oxidized.Statement 2: Noble metals such as gold are most easily oxidized.31. Statement 1: As titrants, multidentate ligands generally react more completely with cations and thus providesharper end points.Statement 2: As titrants, multidentate ligands, they ordinarily react with metal ions in a single-step process,whereas complex formation with unidentate ligands usually involves two or more intermediate species.32. Statement 1: The selectivity of a ligand for one metal ion over another refers to the stability of the complexesformed.Statement 2: The higher the formation constant of the metal-ligand complex, the better the selectivity of theligand for the metal relative to similar complexes formed with other metals.33. Statement 1: A Bronsed acid is a proton donor and can be said to be a Lewis Acid.Statement 2: However, all Lewis acid cannot be called Bronsted base.34. Statement 1: The reactivity of an acid and a base is a function of their strength as chemical compounds.Statement 2: Relatively, the strength of an acid is a measure of the ease of protonation.

Which of the following given statements is false? 1. The electrical conductivity of water is dependent on the temperature of the water sample. Removal of suspended particles by sedimentation depends upon the size and specific gravity of those particles. Suspended solids retained on a filter may remain in suspension if their specific gravity is similar to water while very dense particles passing through the filter may settle. Sodium hydroxide and sodium chloride are both bases. 2. In a sedimentation process, the solid particles settled at the bottom of the container because they are heavier than water and are acted upon by gravity. In the process of distillation, the condenser helps in the conversion of the vapor that goes inside it into liquid. After filtering a mixture using a filter paper, there is more solute at the bottom of the container compared to the contents of the filter paper. In the reaction between dry ferrous sulfate and dry potassium ferricyanide, no change is observed.…

(If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that lead fluoride is more soluble than fill in the blank 1, and lead fluoride is less soluble than fill in the blank 2. It is not possible to determine whether lead fluoride is more or less soluble than fill in the blank 3 by simply comparing Ksp values.

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure. 2. The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC. 4. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…
