Answer:
Chlorine gas is the limiting reactant
11.57 g
Explanation:
The equation of the reaction is;
2Al(s) + 3Cl2(g) -----> 2AlCl3(s)
The limiting reactant will produce the least number of moles of AlCl3.
For Al
Number of moles reacted = 2.43 g/27 g/mol = 0.09 moles
2 moles of Al yields 2 moles of AlCl3
0.09 moles of Al yields 0.09 * 2/2 = 0.09 moles of AlCl3
For Cl2
9.22g/71g/mol = 0.13 moles
3 moles of Cl2 yields 2 moles of AlCl3
0.13 moles of Cl2 yields 0.13 * 2/3 = 0.087 moles of AlCl3
Hence Cl2 is the limiting reactant
b) Mass of product produced = 0.087 moles of AlCl3 * 133g/mol = 11.57 g
Answer:
Uniformitarianism- A theory that geologic process that occur today are similar to those that have occurred in the past
Trace Fossil- A fossil of a foot or trail or other travel of an animal rather than of the animal itself
Solids are generally held together by ionic or strong covalent bonding, and the attractive forces between the atoms, ions, or molecules in solids are very strong. In fact, these forces are so strong that particles in a solid are held in fixed positions and have very little freedom of movement.
hope it helps...!!!
<span>1. B .......... it has less ioni. energy, less likely to form ion and react, therefore its a halogen under Cl on the periodic table, and has a wider radius due to more shells
2. B ...........ionic bond = cation + anion, Mg has charge 2+ and Cl has charge 1- forming MgCl2
also Mg is a metal and Cl is non metal
but H and Cl ions also bond to form hydrogenchloride. but both H and Cl are non-metals. so B is the best answer.</span>
