Answer:
            Option-C (Carboxylic Acid)

Explanation:
                   Vinegar is a solution made up of 95 % water and 5 % Acetic Acid. The structure of Acetic Acid is shown below. Acetic acid belongs to a class of organic compounds called as Caboxylic Acids. The functional group of carboxylic acid contain a carbonyl group bonded to hydroxyl group and an alkyl group (highlighted red in structure).
                    Due to acid nature of this class it can donate the proton bonded to oxygen atom next to carbonyl group and resulting in the formation of resonance stabilized carboxylate ion.

Other examples of Carboxylic acids are,

HCOOH     Formic Acid

CH₃-COOH     Acetic Acid

CH₃-CH₂-COOH     Propionic Acid

CH₃-CH₂-CH₂-COOH     Butanoic Acid

CH₃-CH₂-CH₂-CH₂-COOH     Pentanoic Acid

Answer:

1.60x10⁶ billions of g of CO₂

Explanation:

Let's calculate the production of CO₂ by a single human in a day. The molar mass of glucose is 180.156 g/mol and CO₂ is 44.01 g/mol. By the stoichiometry of the reaction:

1 mol of C₆H₁₂O₆ -------------------------- 6 moles of CO₂

Transforming for mass multiplying the number of moles by the molar mass:

180.156 g of C₆H₁₂O₆ ----------------- 264.06 g of CO₂

4.59x10² g ---------------- x

By a simple direct three rule:

180.156x = 121203.54

x = 672.77 g of CO₂ per day per human

So, in a year, 6.50 billion of human produce:

672.77 * 365 * 6.50 billion = 1.60x10⁶ billions of g of CO₂

"in which direction does this reaction tend to proceed under standard conditions?"
Black_prince [1.1K]

Answer : Right

Explanation : The direction of reaction tends to proceed on right side under standard conditions; If the change in standard free energy ΔG for a particular reaction is negative. Also if the elements in their most stable forms as they exist under standard conditions. Then ΔG determines the direction and extent of chemical change. But under standard conditions the direction of the  reaction will be to right.

Drag each label to the correct location on the chart. Classify each reaction as endothermic or exothermic.
fomenos

A reaction is exothermic if Δ<em>H</em> (or \Delta H _\text{rxn} in some textbooks) is negative:

  • H₂ + Br → 2 HBr, ΔH < 0.
  • CH₄ + 2 O₂ → CO₂ + 2 H₂O, ΔH < 0.

A reaction is endothermic if Δ<em>H</em> is positive:

  • 2 NH₃ → N₂ + 3 H₂, ΔH > 0.
  • 2 HCl → H₂ + Cl₂ ΔH > 0.
<h3>Explanation</h3>

The enthalpy of a system is the sum of its internal energy. ΔH < 0 indicates that the reactants lose internal energy in the reaction. Energy conserves, and those internal energies must have converted to some other form of energy. They typically end up as thermal energy. The reaction will release heat since it is exothermic.

Similarly, ΔH > 0 indicates that the reactants gains internal energy in the reaction. Energy conserves. As a result, the reaction must have gained energy from its surroundings. The reaction will be endothermic since it absorbs heat.
