Syrian hamsters have 21 pairs and two sex chromosomes (44 in total).
Answer:
3.1 * 10^-14
Explanation:
Note that E°cell = 0.0592/n log K
We can obtain E°cell from the standard reduction potentials of cadmium and hydrogen
Anode reaction
H2(g) ----> 2H+ + 2e
Cathode reaction
Cd^2+(aq) + 2e -----> Cd(s)
E°cell = E°cathode - E°anode
E°cathode = –0.40 V
E°anode = 0 V
E°cell = –0.40 V - 0 V
E°cell = –0.40 V
E°cell = 0.0592/n log K
Where n=2 electrons transferred
–0.40 = 0.0592/2 log K
–0.40 = 0.0296 log K
log K = –0.40/0.0296
log K = -13.5135
K = Antilog ( -13.5135)
K = 3.1 * 10^-14
Answer:
The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate.
Explanation:
Water is a molecule composed of hydrogen and oxygen atoms that forms a covalent bond i.e. share electrons. However, due to the fact that the oxygen atom in a water molecule is more electronegative than the hydrogen molecule, it tends to draw electrons towards itself, leaving the hydrogen atom more positive. This causes the POLARITY of water.
To ionize means for the atoms of a compound to dissociate into electrically charged ions (positive and negative) in an aqeous solution. Water is able to ionize because the more electronegative oxygen atom draws the electron from one of its hydrogen atoms, leaving the proton (H+) to dissociate.
Answer:
this can be explained as a non optically active member of a set of stereoisomer, at least two of which are optically active
Explanation:
this means that despite containing two or sterogeonic center the molecules are not chiral
example:
the example above shows at least two choral center and internal mirror plane
