The coefficients that will balance the equation will be 2,3,2.

For a balanced equation, the number of atoms of each element on the reactant side must be equal to those of the product side.

Thus, the balanced equation of the reaction will be:

2Fe + 3Cl2 → 2FeCl3

Consequently, the coefficients of the balanced equation are 2,3,2.

Heat or light could make a decomposition reaction occur. Therefore, option (A) is correct.

The decomposition reactions can be described as in which one reactant breaks into one or more products during the reaction.

The decomposition reaction can be represented as the following equation:

AB     →    A    +   B

Where AB is the parent molecule that acts as a reactant and gives A and B as products.

A decomposition reaction can be possibly an exothermic reaction or endothermic reaction. Thermal decomposition reactions are those in which the energy is supplied to reactant molecules for the decomposition.

For example, the decomposition of calcium carbonate is a thermal decomposition reaction. In the products, carbon dioxide gas and calcium oxide are produced. The decomposition of ozone gas occurs in the presence of light.

Therefore, heat or light can make the decomposition reaction take place.

Answer:

B.  4-methylhex-1-ene

Explanation:

There are 6 carbons for the main molecule of 1-hexene.  They are counted from the first (1) on the terminal C with the double bond (ene).  A methyl group is hanging on carbon number 4, so it is the 4-methyl.

4-methylhex-1-ene.

Answer:

C

Explanation:

The reaction between carbon dioxide and lithium hydroxide can be represented by the equation:

[tex]\displaystyle \text{CO$_2$} + 2\text{LiOH} \longrightarrow \text{Li$_2$CO$_3$}+ \text{H$_2$O}[/tex]

We want to determine the amount of moles of LiOH needed to react completely with 25.5 g of CO₂.

Determine the number of moles of CO₂ in 25.5 g of CO₂:

[tex]\displaystyle 25.5\text{ g CO$_2$} \cdot \frac{1\text{ mol CO$_2$}}{44.01\text{ g CO$_2$}} = 0.579\text{ mol CO$_2$}[/tex]

Use stoichiometry to determine the amount of LiOH necessary. CO₂ and LiOH are in a 1:2 ratio. That is, for every one mole of CO₂ that reacts, two moles of LiOH must also react.

[tex]\displaystyle 0.579\text{ mol CO$_2$} \cdot \frac{2\text{ mol LiOH}}{1\text{ mol CO$_2$}} = 1.16\text{ mol LiOH}[/tex]

In conclusion, our answer is C.

Answer : Stays the same

Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)

There are two types of chemical reactions that may occur.

single-replacement reactions and double-replacement reactions.

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

A + BC ⇒ AC + B

Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.

This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.

The more left the position of a metal in the series, the more reactive metal (easy to release electrons)

Generally, the Volta series used is

Li K Ba Sr Ca Na Mg Al Mn Zn Cr Fe Cd Co Ni Sn Pb H Sb Bi Cu Hg Ag Pt Au

Solid zinc and aqueous lead (II) nitrate react to from aqueous zinc (II) nitrate and solid lead.

Can be expressed in chemical equations :

Zinc + aqueous lead (II) nitrate ⇒aqueous zinc  nitrate + lead metal

Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)

Reactants : Zn and Pb(NO₃)₂

Products : Zn(NO₃)₃ and Pb

The existing Zinc element can replace the Lead element, which is on the right side of Zn,  so the reaction will occur.

Answer:

elastic potential energy

Explanation:

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Answer:

C

Explanation:

The enthalpy of the reactants is greater than that of the products.

The statement is true about the exothermic reaction is the enthalpy of the reactants is greater than that of the products. Therefore, option C is correct.

A chemical reaction involves the movement of energy to or from the environment. An exothermic reaction occurs when energy is transmitted to the environment, raising the ambient temperature. Combustion reactions are an example of an exothermic reaction.

Chemical processes known as exothermic reactions generate heat. Therefore, the H of reaction is negative for exothermic processes. Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

Thus, option C is correct.

Answer: It can affect the shape of sediment because it is scraping very slowly against it causing it to change,

Explanation:

Answer:

Physical conditions like temperature and pressure affect state of matter. ... When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)

Answer:

Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

Answer:

yes.

Explanation:

the definition of a redox reaction is a chemical reaction in which electrons are transferred between two reactants participating in it, meaning, thermal decomposition is a chemical reaction where a substance is being broken down hence, electrons being transfered.

The main difference between both models is that the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.

Lewis Structure is a simplified representation of a molecule's valence shell electrons. It's used to depict how electrons in a molecule are distributed around specific atoms.

Hence the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.
