How would a flood be a limitation for synthetic polymers that rely on natural rubber in its production?

The limiting reagent is lead(II) nitrate, with a theoretical yield of 3.75435 g, resulting in a percent yield of 65.26%. The calculated moles involved in the reaction reflect that 1.20 M potassium chloride is present in 25.0 mL, which converts to 0.03 moles. In contrast, 0.900 M lead(II) nitrate in 15.0 mL results in 0.0135 moles. The limiting reagent, being the one present in smaller quantities, drives the reaction yielding 0.0135 moles of lead(II) chloride, correlating to a mass of 3.75435 g. Finally, given an experimental yield of 2.45 g, the percent yield calculation leads to 65.26%.

Answer:

During this process, energy is released as a bond is formed.

Explanation:

The elements present on the left side of the reaction equation are known as reactants, while those on the right are called the products.

In this case, N(g) and N(g) are the reactants, and N2(g) along with energy are the products.

Post-reaction, N(g) has vanished and has been replaced by N2(g). It confirms that a bond exists between the two N(g).

Moreover, energy has been released as part of the products (indicated on the right side)

The accurate statement is ''A bond is formed and energy is released''

The correct choice is C. It prohibits the exploitation of mineral resources. 

Explanation:

A mixture refers to a substance that contains two or more different kinds of substances that are combined physically.

For instance, air is a mixture that contains oxygen, nitrogen, and other gases.

A heterogeneous mixture is characterized by uneven distribution of solute particles in the solvent.

For example, sand suspended in water is a heterogeneous mixture.

Conversely, a homogeneous mixture is one where the solute particles are uniformly distributed in a solvent.

A homogeneous mixture appears as a clear solution.

For instance, when salt dissolves in water, it forms a homogeneous mixture.

A solution is defined as a mixture of two or more substances combined together.

A compound consists of two or more different elements chemically bonded together in a specific mass ratio.

An element is the simplest form of a substance that comprises only one type of atom.

For example, a piece of sodium is composed solely of sodium atoms.

Conversely, a pure substance refers to a material consisting of just one type of molecule or atom.

For example, , etc are considered pure substances.

Thus, it can be concluded that the air sample can be described using the terms:

• pure chemical substance.

• heterogeneous mixture.

• mixture.

<span>Using PV=nRT, which represents a universal constant for any state, we have: P1V1/n1T1=R and P2V2/n2T2=R; This implies that: P1V1/n1T1=P2V2/n2T2 Thus we can express it as V1/n1=V2/n2. Rearranging yields: V2=V1 x (n2/n1) = 750 mL x ((0.65+0.35)/(0.65)) = 1200 mL = 1.2 L... with 2 significant figures</span>
