Explain what happens in the reaction between sodium hydroxide and hydrochloric acid.Explain how protons are donated and accepted

Artyom0805 [142]

Answer:

Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release of heat. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water – compounds that are ultimately harmless, even beneficial, to human beings.

2) An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids. A reaction between an acid and base is called a neutralization reaction.

On the basis of the information below, the dissolution of FeF2(s) in acidic solution is A. thermodynamically favorable, because

antoniya [11.8K]

Since K3 is greater than 1, the reaction is thermodynamically favorable.

Data;

FeF2 is in an acidic solution
K2 > 1 is thermodynamically favorable
k3 > 1 is not thermodynamically favorable
K1<1 is not thermodynamically favorable

This states that the heat change in a given chemical reaction is the same irrespective of the number of process in which the reaction is effected.

Using Hess Law;

$rxn_3 = rxn_1 * 2rxn_2\\k_3 = k_1 * k_2^2\\k_3 = 2*10^-^6 * (1*10^3)^2\\k_3 = 2$

substituting this using Gibbs law,

$\delta G^0_3 = -RT\ln K_3\\\delta G^0_3 < 0$

Since K3 is greater than 1, the reaction is thermodynamically favorable.

What is described by the amount of energy required to change a gram of a liquid to a gas at the

ehidna [41]

Answer:

Heat of vaporization.

Explanation:

the amount of energy needed to change the specific amount or gram of liquid in to gas phase is called heat of vaporization.

In this liquid is converted into gas phase as because after the boiling point addition of more energy will cause breakage of bonds present in between the liquid molecules which results in the vaporization of liquid.

pentagon [3]

Maple syrup, which comes from the sap of maple trees, contains water and natural sugars. It's a clear, brown liquid and the sugars can’t be separated by filtration. It should be categorized as a homogeneous mixture since the sugar is homogeneously dispersed or mixed in water. It is completely dissolved resulting to uniform properties of the mixture.
