Answer:
11.75 g H2O
Explanation:
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2
MM H2O = 18.02 g/mol
MM CaCO3 = 100 g/mol
? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O
Explanation:
According to https://oureverydaylife.com/lemon-juice-stop-apples-browning-21624.html it days that"
Chemical Reaction
Once added to sliced apples, the ascorbic acid, or vitamin C, in lemon juice creates a barrier between the oxygen and the polyphenol oxidase. Until the lemon juice has evaporated or been completely absorbed, the oxygen reacts with the ascorbic acid, preventing the apple from turning brown".
Most likely it’s crystalline structure, which makes it small granules that are soluble in water. Most, if not all, ionic compounds are salts. And salts dissolve in water.
Hope that’s correct
Cobalt is a metal thus the atoms are bonded together in giant atomic structures and metallic bonds. The atoms attract each other with very strong atomic forces this the resulting structure is giant atomic structures. This provides for the extra strong structure of cobalt.
