RNAS C Practice Test Review 437 Questions with Verified Answers A capacitor and resisitor in parallel - CORRECT ANSWER will have same voltage across since in parallel. if in series, voltage drops would occur they can be treated together If the absolute pressure of a gas is increased from 3 atm to 4 atm at constant volume, then the absolute temperature of the gas will increase by: A. 25%. B. 33%. C. 67%. D. 75% - CORRECT ANSWER B. Assuming the validity of the Ideal-Gas law, PV = n...

Practicals Chemistry AQA A-level Rated A+ Required Practical 1 - titration and making a standard solution Making a standard solution 1. weigh the required mass of solid using a sample bottle on a 2 dp balance. 2. transfer the solid into a beaker using distilled water to wash it out- preventing any solid remaining in the sample bottle. 3. reweigh the sample bottle and work out the difference. 4. Add 100cm3 of distilled water to the beaker to dissolve the solid (small volume of water) using a...

A LEVEL CHEMISTRY WITH VERIFIED QUESTIONS AND ANSWERS Weak acid - an acid that is only slightly ionised/dissociated in aqueous solution Oxidation - loss of electrons Reduction - gain of electrons Ionic bonding - The electrostatic attraction between oppositely charged ions Covalent bonds - sharing of a pair of electrons Electronegativity - the ability of an atom to attract the electrons in a covalent bond Relative atomic mass - The weighted mean mass of an atom of an element ...

True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False...
