Answer:
Option D
Explanation:
Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)
Mathematically, it can be represented as
Substituting the given values, we get-
Hence, option D is correct
Answer:
Hope dat helps
Explanation:
All the data related to the potential energy diagram is shown in the attached image.
Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).
Enthalpy change (ΔH) is the difference in energy between reactants and products.
ΔH = E of products - E of reactants.
Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as
From the image, the points marked represents:
Point A represents the potential energy of the reactants.
Point B represents the intermediate state or transition state in a reaction.
Point C represents the potential energy of the products.
Arrow D represents the activation energy of the reaction.
Arrow E represents the enthalpy of the reaction.
Hence, arrow E represents the enthalpy of the reaction.
Balanced chemical reaction:
2NaCl(aq) + Hg₂(C₂H₃O₂)₂(aq) → Hg₂Cl₂(s) + 2NaC₂H₃O₂<span>(aq).
</span>NaCl - sodium chloride.
Hg₂(C₂H₃O₂)₂ - mercury(I) acetate.
NaC₂H₃O₂ - sodium acetate.
Hg₂Cl₂ - mercury(I) chloride or <span>mercurous chloride</span>, low solubility in water.
Oxidation number of sodium is +1 and for mercury is also +1.
Answer: the answer would be D
Explanation:In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. an example of this would be a green house in the winter the sun is still out but the windows keep out the cold air so the sun just heats up the air inside
