No. of moles of calcium chloride = molarity × volume of solution in L
No. of moles of calcium chloride = 2.5 ×0.5 = 1.25 mole
No. of moles of calcium chloride = mass of calcium chloride / molar mass of calcium chloride
1.25 mole = mass of calcium chloride / 110.98 g/mol
mass of calcium chloride = 1.25 ×110.98 = 139 g
Answer: 2.744 x 1025 molecules
False. Pb is lower than Al in the reactivity series. It cannot replace aluminium in AlCl3
Molecular crystals does iodine, dry ice (CO2) , ice and plastic form. It is becuase<span> is that all four are made of nonmetal elements.Which implies any compounds are made up of molecule.</span>
