Answer:
11 is the coefficient for C to balance the equation
Explanation:
C₁₂H₂₂O₁₁(s) + H₂SO₄(aq) + 1/2 O₂(g) → 11C(s) + CO₂(g) + 12H₂O(g) + SO₂(g)
12 Carbons in left side → 12 Carbons in right side
12 in sucrose → 11 in solid C + 1 in the CO₂
24 Hydrogens in left side → 24 Hydrogens in right side
22 in sucrose + 2 in sulfuric → 24 in water vapor
1 S in left side → 1 S in right side
1 S in sulfuric → 1 S in sulfur dioxide
16 O in left side → 16 O in right side
11 O in sucrose + 4 in sulfuric + 1 O at ground state → 2 O in carbon dioxide + 12 in water vapor + 2 in sulfur dioxide
2.82 inches is are equivalent to 7.16 cm.
The volume of the cube ;
7.16 × 7.16 × 7.16 = 367.06 cm³
The density of titanium is 4.5 g/cm³
Therefore; mass will be 4.5 × 367.06 = 1651.77 g
1 mole of titanium has 47.867 g
thus, 1651.77 g is equivalent to 1651.77/ 47.867 = 34.507 moles
According to the Avagadro's constant 1 mole = 6.022 × 10∧23 atoms
Therefore, we get 6.022 × 10∧23 × 34.507 = 2.078 ×10∧25 atoms
The statement that describes the chemical reaction is D chlorine gas reacts with potassium bromide to form potassium chloride in solution and liquid bromide<span>. The symbol "Cl" represents chlorine. The symbols in the brackets show the physical state of the substance, (g) is gaseous, (s) is solid, (aq) is aqueous and (l) is liquid.</span>
