Good conductor of electricity
Answer:
The answer to your question is 3.5 moles of H₂
Explanation:
Data
moles of H₂ = ?
moles of Zn = 3.5 moles
moles of HCl = excess
Process
1.- Write the balanced chemical reaction
Zn + 2HCl ⇒ ZnCl₂ + H₂
Reactants Elements Products
1 Zn 1
2 Cl 2
2 H 2
2.- Use the coefficients of the balanced reaction to calculate the moles of H₂
1 mol of Zn ----------------- 1 mol of H₂
3.5 moles of Zn ------------- x
x = (3.5 x 1)/1
x = 3.5 moles of H₂
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
The answer is Metalloids!
The answer is the most probable location of electrons in an atom
