The charge would be -2 because there are 2 more electrons than protons, and electrons have a negative charge.
Answer:
C) 3
Explanation:
Given data;
Number of moles of oxygen produced = ?
Moles of KClO₃ decomposed = 2 mol
Solution:
Chemical equation;
2KClO₃ → 2KCl + 3O₂
Now we will compare the moles of KClO₃ with O₂
KClO₃ : O₂
2 : 3
Thus, 3 moles of oxygen are produced.
Hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
