Reaction a is extremely fast whereas reaction b is very slow. based on this information, which of the following statements must be true? a) reaction a must b catalyzed by an enzyme b) the equilibrium constant for reaction a is greater than 1 an the equilibrium constant for reaction b must be less than c) the equilibrium constant for reaction a is less than 1 and the equil ibrium constant for reaction b is greatr than d) reaction a has a lower activation energy barrier than reaction b e) reaction a has a higher activation energy barrier than reaction b 10. which of the following statements are true? a) covalent interactions are vital to the cell because they are reversible b) non-covalent interactions are vital to the cell because they are irreversible c) polyhydroxy aldehydes and ketones make up carbohydrate polymers d) the strength of an electrostatic interaction is highly dependent of its angle (i. e. directionality) e) all of the above are true

A6.10 m nacl can be made by adding [x]g of nacl to a container and making the volume of water up to the 1.00 l line

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
