When one atom of hydrogen (h) combines with one atom of chlorine (cl), a polar covalent bond forms between the h and the more electronegative cl, resulting in a molecule of hcl. which of the following describes the arrangement of valence electrons in a bond between h and cl?
a. the valence electrons are shared equally between h and cl.
b. the valence electrons spend more time around the atom of h.
c. the valence electrons spend more time around the atom of cl.
d. the valence electrons are given up by the h and gained by the cl.

At 300 mm hg, a gas has a volume of 380 l, what is the volume at standard pressure

What substance has a mass of 9.5g and volume of 2.1cm^3

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
