Answer: carbonyl group C=O

Explanation:

Formaldehyde is an organic compound, it is the simplest form of Aldehydes. It formula is CH2O and has a carbonyl functional group, C=O. The general formula for adehydes is R-COH. The carbon atom is bonded to oxygen with a double bond and one of the two remaining bonds is occupied by hydrogen, and the other by an alkyl group.

One of the properties of adehydes is their solubility in water. The lower members (up to 4 carbons) of aldehydes are soluble in water due to H-bonding. Ofcourse the the higher members are not soluble in water because their hydrophobic long chains.

Aldehydes contain carbonyl group, therefore they undergo reactions like nucleophilic addition reactions, oxidation, reduction, halogenation.

What is the pH of a 3.5 x 10-5 M solution of HCl?

kolezko [41]

Answer:

4.46

Explanation:

Applying,

pH = -log(H⁺)....................... Equation 1

Where H⁺ = Hydrogen ion concentration of HCl solution

From the question,

Given: H⁺ = 3.5×10⁻⁵ M

Substitute these values into equation 1

pH = -log(3.5×10⁻⁵)

pH = 4.46

Hence the pH of HCl solution is 4.46

In the lab, you mix two solutions (each originally at the same temperature) and the temperature of the resulting solution decrea

Archy [21]

Answer:

The correct answer is option B.

Explanation:

Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.

The total enthalpy of the reaction $(\Delta H)$ comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.

The total enthalpy of the reaction $(\Delta H)$ comes out to be negative.

On mixing of both solution we had observed that temperature of the resulting solution was lowered this is because the energy was absorbed during the chemical reaction.

Karolina [17]

Answer: Energy is being absorbed as the reaction proceeds

Explanation:

Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and $\Delta H$ for the reaction comes out to be positive.

Exergonic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ for the reaction comes out to be negative.

Thus an endergonic reaction refers to a chemical reaction in which Energy is being absorbed as the reaction proceeds.
