Answer: oxygen
Explanations
The products of photosynthesis are glucose and oxygen.
<span>In crystallography, the terms crystal system, crystal family, and lattice system each refer to one ... In total there are seven crystal systems: triclinic, monoclinic, orthorhombic, ..... A polar crystal possess a "unique" axis (found in no other directions) such ... lattices in three dimensions; each can apply in one lattice system only.</span><span>

The balanced chemical equation is:
<h3>2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + 4H₂O</h3>
Chemical equation can be balance by simply doing a head count of the different elements in the reactants and products to verified they are equal.
The equation given in the question above can be balanced as follow:
H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + H₂O
There are 2 atoms of SO₄ on the right side and 1 atom on the left side. It can be balance by writing 2 before H₂SO₄ as shown below:
2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + H₂O
There are a total of 8 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 4 before H₂O as shown below:
2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + 4H₂O
Thus, the equation is balanced.

Reactants + Energy → Products. Note: ΔH represents the change in energy. In endothermic reactions, the temperature of the products is typically lower than the temperature of the reactants. ... The energy needed for the reaction to take place comes from the water, which gets colder as the reaction proceeds.
<span>Silver nitrate (AgNO3) is a colorless solution . when we add silver nitrate to dilute HCl we get a white precipitate of silver chloride
But here as you employed a concentrated hydrochloric acid initially the precipitate of silver chloride is formed but it immediately dissolves in HCl leaving a colour less solution
it all depends on the amount of HCl taken and amount of silver nitrate added to it
if we add equimolar quantities of both we will get a clear solution
if we add excess of silver nitrate we will get a small amount of white precipitate
AgNO3(solution) + Conc.HCl ----------> AgCl(Solution) + HNO3
AgNO3 (excess) + Conc.HCl --------> AgCl(Small white ppt) + HNO3</span>
