Hey there.
By adding up all the "exponents," you'll get a number of 19. By looking at a periodic table, the element of such an atomic number is potassium or K.
1) List the reactants: sodium bicarbonate (NaHCO₃) and citric acid (H₃C₆H₅O₇).
Reactants undergo change during a chemical reaction.
2) List the products: water (H₂O), carbon dioxide (CO₂) and sodium citrate (Na₃C₆H₅O₇).
Products are the substances formed from chemical reactions.
3) The balanced chemical equation:
3NaHCO₃ + H₃C₆H₅O₇ → 3H₂O + 3CO₂ + Na₃C₆H₅O₇.
Answer:
Empirical formula is CCl₄
Explanation:
Given data:
Percentage of carbon = 7.70%
Percentage of chlorine = 92.3%
Empirical formula = ?
Solution:
Number of gram atoms of Cl = 92.3 / 35.5 = 2.6
Number of gram atoms of C = 7.70 / 12 = 0.64
Atomic ratio:
C : Cl
0.64/0.64 : 2.6/0.64
1 : 4
C : Cl = 1 : 4
Empirical formula is CCl₄.
