1,2 I think it’s two tho I’m not sure
<span>An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture isused to achieve freezing-point depression for cold environments and also achieves boiling-point elevation to allow higher coolant temperature.</span>
The solution would be like this for this specific problem:
4 NaOCl + S2O3{2-} + 2
OH{-} → 2 SO4{2-} + H2O + 4 NaCl
<span>(0.00456 L) x (0.100 mol/L
S2O3{2-}) x (4 mol NaOCl / 1 mol S2O3{2-}) x (100.0 mL / 25 mL) x </span><span>
<span>(74.4422 g NaClO/mol) = 0.54313 g </span></span>
<span>(5.00 mL) x (1.08 g/mL) =
5.40 g solution </span>
(0.54313 g) / (5.40 g) =
0.101 = 10.1%
So, the average percent by mass of NaClO in the
commercial bleach is 10.1%.
Answer:

Explanation:
solve examole number 2 .....
B. Nuclear fission reactions are slowed down as well.
Neutron moderation is a substance which slows down neutron. In some reaction moderator is same as coolant.
This is also used to slow down nuclear fission reaction and continue chain reactions.
The collision between neutron and nuclei is more elastic and more neutrons will be slowed due to size of the neutron.
