Explanation:
La reacción de descomposición del CaCO₃ es:
CaCO₃ → CO₂ + CaO
<em>Donde 1 mol de CaCO₃ al descomponerse produce 1 mol de CO₂ y 1 mol de CaO.</em>
Usando la ley general de los gases, las moles de dioxido de carbono son:
PV = nRT.
<em>Donde P es presión (1atm), V es volumen (20L), n son moles de gas, R es la constante de los gases (0.082atmL/molK) y T es temperatura absoluta (15 + 273.15 = 288.15K). </em>Reemplazando los valores en la ecuación:
PV / RT = n
1atmₓ20L / 0.082atmL/molKₓ288.15K = 0.846 moles
Como 1 mol de CO₂ es producido desde 1 mol de CaCO₃, las moles iniciales de CaCO₃ son 0.846moles.
La masa molar de CaCO₃ es 100.087g/mol. Así, la masa de 0.846moles de CaCO₃ es:
0.846moles ₓ (100.087g / mol) = <em>84.7g de CaCO₃</em>
Así, la pureza del marmol es:
(84.7g de CaCO₃ / 125g) ₓ 100<em> = </em>

The number of electrons it take to fill the mos formed from the combination of the 3s orbitals of two atoms simply is 14 electrons.
<h3>How electrons are distributed in the 3s orbitals.</h3>
The 3s orbital possess two different spherical nodes which is highly connected with the principal quantum number. In order words, it has 2 radial nodes. Also the shape of the 3s orbital is spherical in shape.
That being said, from the context of the above given task, the number of electrons which fill the mos formed from the combination of the 3s orbitals of two atoms is fourteen electrons.
However, the electron configuration of an atom simply is the arrangement of electrons in the electron shell or orbit of the atom of that element.
In conclusion, it can be deduced from above s orbital has a maximum of two electrons and this energy increases as the orbitals increases.

I believe the answer is Chlorophyll. During photosynthesis light energy from the sun is trapped by chlorophyll, it is then used to break down water molecules to hydrogen ions and oxygen gas. This represent the first stage of photosynthesis called light dependent stage. The hydrogen ions formed in this stage then joins the light independent stage (dark stage) and oxygen is released to the atmosphere or released to the atmosphere.
Answer:
Reactants: 6 molecules of carbon (iv) oxide and 6 molecules of water
Products: 1 molecule of glucose with 6 molecules of oxygen
Explanation:
Reactants: the left-hand side; and
Products: Right hand side
The compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.
A chromatogram is an output that shows the extent of separation of the components of a mixture. If the Rf is high, then it means that the substance traveled a large distance through the plate and vice versa.
Similarly, the molecular mass of the substances correlate with the Rf value observed for each component. The components with high molecular mass always show a low Rf value.
This implies that the lowest Rf value corresponds to the largest relative molecular mass. Thus, the compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.
