Answer:2
Explanation:because the compound is CaI2, Ca needs to lose 2 electrons and I needs to gain 1 electron to reach an octet and so there will be 2 I atoms therefore 2 electron transfer
Answer:
The solubility of the salt is
46.75g salt/100g of H2O
Explanation:
If 7.70g of water can dissolve 3.60g at 21°C
That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g
The solubility of the salt is
46.75g salt/100g of H2O
Courtney’s in minerals can vary due to impurities but is usually diagnostic we determine the relative hardness of minerals using a scale diversity bye mineralogists Freidrich Mohs The scale assigned hardness Tuten common index minerals and is based up on the ability of one mineral to scratch another
