Which reaction occurs when hydrogen ions react with hydroxide ions to form water?A. substitution
B. saponification
C. ionization
D. neutralization
Answers
Answer: D. neutralization
Explanation:
1. Substitution reaction is defined as the reaction in which one atom replaces the other atom from the compound.
2. Saponification is a reaction in which fatty acids are made to react with alkalis to form sodium salt of fatty acids called as soaps.
3. Ionization is a type of chemical reaction in which a substance ionizes when dissolved in water.
4. Neutralization is a type of chemical reaction in which an acid reacts with base to produce salt and water.

Final answer:
The symbol for the compound dinitrogen trisulfide is N2S3. It is derived from the number of nitrogen and sulfur atoms present in the compound.
Explanation:
The chemical compound dinitrogen trisulfide is composed of two elements: nitrogen (N) and sulfur (S). When we name the compound according to IUPAC nomenclature rules, we consider the number of each type of atom present. Dinitrogen means there are two nitrogen atoms, represented by the subscript 2, and trisulfide implies that there are three sulfur atoms, signified by the subscript 3. Hence, the symbol or chemical formula for dinitrogen trisulfide is N2S3.

2. 2C(s)+3H2(g) -> C2H6(g)
3. N2(g) +3H2(g)->2NH3(g)

Answers
Answer:
3. N2(g) +3H2(g)->2NH3(g)
Explanation:
Reactions can be broadly classified as endothermic and exothermic reactions. In the former, energy or heat is absorbed by the reactants and the enthalpy change of the reaction is positive. In the later, heat is released ans the enthalpy change of the reaction is negative.
For the given reactions, the enthalpy change or ΔH values are:
1. 2C(s) + 2H2(g) -> C2H4(g) ΔH = +52.4 kJ
2. 2C(s)+3H2(g) -> C2H6(g) ΔH = -84 kj
3. N2(g) +3H2(g)->2NH3(g) ΔH = -91.8 kJ
4. N2(g)+O2(g) -> 2NO(g) ΔH = +182.6 kJ
Reactions 1 and 4 are endothermic while reactions 2 and 3 are exothermic in which heat is released.
More negative the ΔH value, greater is the amount of heat released.
Thus, reaction 3, represents a change resulting in the greatest quantity of energy released

Transfer of neutrons and protons never takes place in a chemical reaction (you have to talk about nuclear reactions instead), and the sharing of electrons takes place in a covalent bond.
Answer = Transfer of electrons.
The formation of an ionic bond involves .
Further Explanation:
Chemical bond is termed as the attractive force that is present between various atoms, ions or molecules. The existence of different chemical compounds is a result of chemical bonds. These bonds can be formed by electron transfer or electron sharing. Protons and neutrons never participate in the bond formation.
Covalent bond
The mutual sharing of electrons between the bonded atoms results in the formation of covalent bonds. Covalent compounds are formed due to presence of these bonds. This type of bonding usually takes place between two or more non-metals.
Ionic bond
The interaction between a metal and a non-metal is defined as an ionic bond. It occurs via the formation of ions by the respective neutral atoms. Here the electrons are completely transferred from metals to non-metals. Metals form cations by the loss of electrons while non-metals form anions by the gain of electrons.
Ionic compounds exist as a result of ionic bonds are called ionic compounds. These compounds are hard solids, good conductors of heat and electricity, have high heat of fusion and high boiling and melting points.
Therefore the formation of ionic bond involves the transfer of electrons.

The examples that represent potential energy are:
A. A candy bar
B. A stretched rubber band
D. A roller coaster at the top of a hill
What is Potential energy?
It is the stored energy in any object or system by virtue of its position or arrangement of parts. This energy depicts zero motion or movement unlike kinetic energy. For example : A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
Thus, correct options are A, B and D.

Answer:
A candy bar
A stretched rubber band
A roller coaster at the top of a hill
Explanation:
Potential energy is the energy present as a result of the position of an object. This energy depicts zero motion or movement unlike kinetic energy.
A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
The other option choices depicts a type of movement .This is why the three option choices are correct in this scenario.
