Answer:
An atom that has fewer neutrons than protons and more electrons than protons is a negative ion. The negatively charged particles in an atom are the electrons. The charge an atom carries depends on the balance between the number of protons and electrons in an atom.
Explanation:
The compound with a chemical formula of C₃H₈ is propane. The subscripts actually represent the number of the individual atoms in 1 particle of the compound. Since there are the same number of atoms per mole of any substance, the subscript can also represent the moles. Through stoichiometric calculations, the solution is as follows:
Moles of Carbon = 11.2 moles H * 3 mol C/8 mol H = <em>4.2 moles</em>
Answer:
(NH₄)₂CO₃ (aq) + MgSO₄(aq) → (NH₄)₂SO₄(aq) + MgCO₃ (s) ↓
Explanation:
We determine the reactants:
(NH₄)₂CO₃ → Ammonium carbonate
MgSO₄ → Magnesium sulfate
We determine the products:
(NH₄)₂SO₄ ; MgCO₃
All the salts from carbonates are precipitates:
(NH₄)₂CO₃ (aq) + MgSO₄(aq) → (NH₄)₂SO₄(aq) + MgCO₃ (s) ↓
Ratio is all 1:1. 1 mol of ammonium carbonate reacts to 1 mol of magnessium sulfate in order to produce 1 mol of ammonium sulfate and 1 mol of magnessium carbonate.
Answer:
atomic mass. You will have created an isotope.
Explanation:
Answer:
3) 2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)
Explanation:
KOH is a strong base and a H2SO4 is a strong acid. The two react in a neutralization reaction, producing a salt and water.
