D.The products will have at least 2 Na atoms and 1 O atom.
<h3>Further explanation
</h3>
Conservation of mass states that
<em>In a closed system, the masses before and after the reaction are the same
</em>
So it can be concluded
- mass of the reactants = mass of the products
- mass cannot be created or destroyed
- The number of atoms involved in a reaction remains the same⇒ number of moles also the same
- chemical equation in balanced form
So the number of atoms in reactants and products remains the same
Because one of the reactants in a reaction is Na₂O, so <em>The products will have at least 2 Na atoms and 1 O atom.</em>
The diameter of the model would be
63.1 m.
The diameter of a hydrogen atom is 1.06 × 10⁻¹⁰ m.
The diameter of a proton is 1.68 × 10⁻¹⁵ m.
The ratio of their diameters is
= 6.31 × 10⁴
So the diameter of your model would be 6.31 × 10⁴ mm
.
6.31 × 10⁴ mm ×
= 63.1 m
Answer:
La constante de equilibrio (K) se expresa como la relación entre las concentraciones molares (mol/l) de reactivos y productos. Su valor en una reacción química depende de la temperatura, por lo que ésta siempre debe especificarse.
