D.
The products will have at least 2 Na atoms and 1 O atom.
<h3>Further explanation</h3>
If we refer to the law of mass conservation, which states that
<em>In a closed system, the masses before and after the reaction are the same
</em>
then the number of atoms in the reactance will be the same as the number of atoms in the product
In this problem it is known that Na₂O is one of the reactants so that the product of Na atoms and O atoms will at least equal the number of atoms in the bond, namely 2 Na and 1 O
Like an example of this Na₂O reaction:
Na₂O + H₂O ⇒ 2 NaOH
Na : left =2, right = 2
O : left=2, right = 2
Answer:
P₂ = 130.18 kPa
Explanation:
In this case, we need to apply the Gay-Lussack's law assuming that the volume of the container remains constant. If that's the case, then:
P₁/T₁ = P₂/T₂ (1)
From here, we can solve for the Pressure at 273 K:
P₂ = P₁ * T₂ / T₁ (2)
Now, all we need to do is replace the given data and solve for P₂:
P₂ = 340 * 273 / 713
<h2>
P₂ = 130.18 kPa</h2>
Hope this helps
Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond). They are considered "simple" because they do not have reactive groups like −OH or −Cl attached directly to the carbon atom in the carbonyl group, as in carboxylic acids containing −COOH<span>.
So your answer would be D.).
I hope that this helps. :)</span>
Oxygen and glucose and energy. <span />
When gases dissolve in gases or when liquids and gases dissolve in liquids, particles movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.
Explanation:
When gases dissolve in gases or when liquids and gases dissolve in liquids, particle movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.
Solid particles do not dissolve easily like liquids and gases dissolve. Solid particles when dissolved in solid the particles moves very little. After getting heated and becomes molten then they get mixed.
But in the liquids and gases atoms moves and the particles get eventually spread and also get mixed after cooled.
