Bonding electrons are involved in chemical bonding these electrons have their valnce shell incomplete
We know because of DNA testing in general.
So we have Barium nitrate with a solubility of 8.7g in 100g water at 20°C.
using that relation
i.e.
8.7g (barium nitrate) =100g (water)
1g barium nitrate = 100/8.7 g water
27g barium nitrate = (100/ 8.7 ) × 27
= 310.34 g
therefore,
you need 310.34g of water is in the jar.
It gets hotter because the core is the outside of the eath and the mantel is the more inside/hope i helped
