NEED THE ANSWER !!! NOW i have like an hour
ryzh [129]

Answer No 1:

The chemical model that is flawed is:

4 C2 + S8 → 4 CS2

In this reaction, there are more number of carbon atoms in the reactants but lesser number of cabon atoms in the products. For a reaction to be balanced, there should be the same number  of atoms in the reactants and products. Hence, option A does not represent a balanced equation.

<em>Answer No 2:</em>

The correct option is B) The model shows an unbalanced number of carbon atoms.

Consider the equation:

4 C2 + S8 → 4 CS2

In the reactants side of the equation, there are 8 atoms of carbon. In the products side there are only four carbon atoms. This shows that this equation in not balanced because of the carbon atoms.

The number of sulfur atoms remains same before the reaction and after the reaction. There are eight sulfur atoms in the reactants as well as products.

Which of the following equations represents Photosynthesis? 16CO2 + 6H2O -----&gt; C6H12O6 + 6O22C6H12O6 + 6O2 -----&gt; CO2 + 6
lidiya [134]

Answer:

  • 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Explanation:

<em>Photosynthesis</em> is the chemical process carried out by plants for the conversion of inorganic matter (carbon dioxide and water) into organic matter (glucose) with the release of oxygen, using light (sun energy).

So the chemical process may be represented by:

  • <u>Word equation: </u>

        carbon dioxide + water + sun energy → glucose + oxygen

  • <u>Skeleton equation:</u>

       CO₂ + H₂O + sun energy → C₆H₁₂O₆ + O₂

  • <u>Balanced chemical equation:</u>

       6CO₂ + 6H₂O + sun energy → C₆H₁₂O₆ + 6O₂

  • <u>Supressing the energy to show only the chemical compounds:</u>

        6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
