The transfer of electrons forms strong bonds between ions I’m pretty sure
The density will become less, this is because thing with less density float to the top when things with more density float to the bottom. It also becomes colder.
Children should not be put into the situations such as the one depicted in this given item. They are still to young to weigh in as to which parent will they will be happier with. Also, they will be very much burdened with the idea of splitting parents disallowing them to focus on other things currently going on.
The correct name for the hydrate salt is calculated as follows
calculate the mass of water =mass of hydrated salt- mass of anhydrous salt
4.56-2.92=1.64g
mass of anhydrous salt (CuSo4)= 2.92g
calculate the mole of water and anhydrous salt
that is
moles =mass/molar mass
moles of water = 1.64g/18g/mol= 0.0911 moles
moles of CUSO4 =2.92g/ 159.5 g/mol=0.0183 moles
find the moles ratio by dividing with the smallest moles that is 0.0183 moles
for H20 = 0.0911/0.0183= 5
CuSO4 = 0.0183/0.0183=1
the formula hydrate salt = CuSO4.5H20 which is known as copper (ii) sulfate pentahydrate
