The first task you are assigned in your summer laboratory job is to prepare a concentrated naoh stock solution. the molecular weight of naoh is 40. how many grams of solid naoh will you need to weigh out to obtain a 500 ml solution that has a concentration of 10 m? (a) 800 g (b) 200 g (c) 400 g (d) 160 g you have a concentrated stock solution of 10 m naoh and want to use it to produce a 150 ml solution of 3 m naoh. what volume of water and stock solutions will you measure out to make this new solution? (a) 135 ml of water, 15 ml of naoh stock (b) 115 ml of water, 35 ml of naoh stock (c) 100 ml of water, 50 ml of naoh stock (d) 105 ml of water, 45 ml of naoh stock 2-10 an ionic bond between two atoms is formed as a result of the (a) sharing of electrons (b) loss of a neutron from one atom (c) loss of electrons from both atoms loss of a proton from one atom (e) transfer of electrons from one atom to the other (d) for each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. not all words or phrases will be used; each word or phrase should be used only once. whereas ionic bonds form an) ..covalent bonds between atoms form an) _. these covalent bonds have a characteristic bond and become stronger and more rigid when two electrons are shared in an) equal sharing of electrons yields a(n) covalent bond. if one atom participating in the bond has a stronger affinity for the electron, this produces a partial negative charge on one atom and a partial positive charge on the other. these _covalent bonds should not be confused with the weaker bonds that are critical for the three- dimensional structure of biological molecules and for interactions between these molecules. charge covalent double bond ionic length molecule noncovalent nonpolar polar salt single bond weight
