So,
Formate has a resonating double bond.
In molecular orbital theory, the resonating electrons are actually delocalized and are shared between the two oxygens. So the carbon-oxygen bonds can be described as 1.5-bonds (option B). I'm not sure if option C is correct, however, because the likelihood of both delocalized electrons being in the area of one oxygen atom is less than 50%.<span />
Answer : Half reaction is defined as the reaction which will be <span>either the oxidation or reduction </span>reaction<span> of particular species in a given redox </span>reaction<span>.
So as per the definition in the reaction of,
</span>

<span>
</span>

<span>
here on left and right side </span>

will get cancelled.
and we will get,

Here,

...this is oxidation reaction as Ba is getting reduced to

by losing 2 electrons.
whereas,on the other hand,

...this is reduction reaction as

is getting reduced to Zn by gaining 2 electrons.
<span>One example of bacteria that live in an extreme environment are the thermophilic species that live in the hot springs of Yellowstone National Park. Thermophilic means heat-loving and the waters in which these bacteria live can rise above 70 degrees Celcius after being heated by lava below the surface. Most life would die at that temperature however some bacteria have evolved to survive the extreme heat.</span>
Answer:
Neutrons- 9 Electrons- 8
Explanation:
Protons equals electrons and since the atomic# of oxygen is 8, 8 is the proton and 8 will be the electrons a s well since it isn't an ion. You subtract 8 from the 17 to get 9 as the neutron.
