I just googled the structures for each molecule cuz I don't have an image of them otherwise. They are all polar except for carbon tetrachloride.
Answer:
Chromatography is used to separate mixtures of substances into their components.They all have a stationary phase (a solid, or a liquid supported on a solid)
Explanation:
it's where the things stay still until the mobile phase moves through and takes the components
Answer:
3.46*10⁻²² kJ
Explanation:
By the Avogadro's number, 1 mole of electrons at 1 mole of atoms correspond to 6.02x10²³ electrons. So it's necessary 208.4 kJ to remove 6.02x10²³ electrons. To remove a single electron:
6.02*10²³ electrons ---------------- 208.4 kJ
1 electron ---------------- x
By a simple direct three rule:
6.02*10²³ x = 208.4
x = 3.46*10⁻²² kJ
The relation between T1 and T2 is T1= T2.
when 200 mL are mixed so, we will have twice the number of moles of water
and twice as much heat will be released this has to heat twice of the mass of the
water, so the temperature rises as the same
