Answer:
0.0493 moles de Titanio
Explanation:
Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:
<em>Volumen de la esfera:</em>
<em>Volumen esfera = 4/3π * Radio³</em>
Volumen = 0.5236cm³
En m³ (1m³ = 1x10⁶cm³):
0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³
<em>Masa en gramos:</em>
5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio
<em>Moles -Masa molar Ti: 47.867g/mol-:</em>
2.36g de Titanio * (1mol / 47.867g) =
<h3>0.0493 moles de Titanio</h3>
Answer:a formula giving the number of atoms of each of the elements present in one molecule of a specific compound.
Explanation:
Answer:
Zn + 2 HCl → ZnCl₂ + H₂
Explanation:
We have to complete this single replacement reaction.
Zn(s) + HCl(aq) →
We need to decide if Zn will replace H⁺ or Cl⁻. Zn can form the cation Zn²⁺ but it does not have a negative oxidation number to form an anion. As a consequence, the cation Zn²⁺ will replace the cation H⁺ to form ZnCl₂. H₂ will be released as a gas.
Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)
Answer:
K = 0.167
Explanation:
The equilibrium constant, K of a reaction, is defined as the ratio of the concentrations of products and concentrations of reactants.
For the reactions:
A + B ⇄ C + D
For the definition, K is:
K = [C] [D] / [A] [B]
K = [4.0M] [4.0M] / [9.6M] [10.0M]
<h3>K = 0.167</h3>
