The balanced chemical reaction is:
2HCl + Ca = CaCl2 + H2
We are given the amount of the reactants to be used for the reaction. These values will be the starting point of our calculations.
100 g HCl ( 1 mol HCl / 36.46 g HCl ) = 2.74 mol HCl
100 g Ca ( 1 mol Ca / 40.08 g ) = 2.08 mol Ca
From the reaction, the mole ratio of the reactants is 2:1 where every 2 moles of hydrochloric acid, 1 mole of calcium is required. Therefore, the limiting reactant for this case is calcium.
He will most likely find that the sand has sunken to the bottom because the molecules in sand are to powerful to break apart and disslove.

if both parents are heterozygous then the table will always look like this. the chances of the offspring being heterozygous are 50%. the offspring has a 25% chance of having two recessive traits and a 25% chance of having two dominant traits.
Answer:
Titanium
Explanation:
BCC i.e. body-centered cubic is a type of non-primitive unit cell.
In bcc type crystal structure the atoms are arranged in the corners of the unit cell and also on the center of the body of that unit cell.
Among the given options Titanium is the only metal which does not form bcc type crystal structure.
Titanium forms hcp (hexagonal close packing ) type of crystal structure.
The coordination number of hcp is 12 and it is ABAB type lattice.
