Yes, Benzylamine is miscible, meaning it is soluble at all amounts.
Now, balance the equation:
in gaseous state exist as a diatomic molecule.
Answer:
It's D. On the surface of the solid.
Explanation:
If the reactant is a solid, the surface area of the solid will impact how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the faster the reaction will be.
Answer:
Likely 
(indium.)
Explanation:
Number of atoms: 
.
Dividing, 
, the number of atoms by the Avogadro constant, 
, would give the number of moles of atoms in this sample:
.
The mass of that many atom is 
. Estimate the average mass of one mole of atoms in this sample:
.
The average mass of one mole of atoms of an element (
in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass 
. Indium, , is the closest match.
Balanced chemical equation: 2H2 + O2 → 2H2O
The limiting reagent will be H2
All 10.39 mol of H2 will be used up produce 10.39 mol of H20
The excess reagent will be O2 and there will be 5.78 mols left over
