The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

Gloria is writing the chemical formula for a compound using its chemical name. She has just identified the names of the elements
disa [49]
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.

n‑methyl‑2‑pyrrolidone is an aprotic solvent used in many industrial processes. draw the structure of the product formed when it
kotegsom [21]

The structure of n‑methyl‑2‑pyrrolidone when it is heated with aqueous acid. product is given below

<h3 /><h3>What is  aprotic solvent?</h3>

A polar solvent without an acidic proton is known as a polar aprotic solvent. These solvents don't include hydroxyl or amine groups. These solvents can act as proton acceptors, but unlike protic solvents, they do not act as proton donors in hydrogen bonding.

After being exposed to a strong aqueous acidic media and being heated, N-methyl-2-pyrrolidone opens up, forming a molecule with a carboxylic group at one end and a protonated nitrogen atom with a methyl group connected to it at the other.

Alcohol, water, hydrogen fluoride, formic acid, acetic acid, ammonia, methanol, ethanol, and other well-known substances are a few examples of polar protic solvents. Polar aprotic solvents, on the other hand, lack acidic protons and do not function as donors during hydrogen bonding.

Barbara is conducting an experiment to observe heat flow. She places one piece of metal in a freezer at -18 degrees Celsius (°C)
yulyashka [42]

<u>Answer:</u> The correct answer is heat will flow from the boiling water into the frozen metal.

<u>Explanation:</u>

According to the law of conservation of energy, energy cannot be destroyed nor created but it can be transformed from 1 form to another form.

There are 3 processes of heat transfer:

  1. <u>Conduction:</u> This type of heat transfer occurs when there is direct contact between the two objects.
  2. <u>Convection:</u> This type of heat transfer occurs when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents.  
  3. <u>Radiation:</u> This type of heat transfer occurs when there is a direct transfer of energy through space.

The heat moves from a hot surface to a cold surface to maintain equilibrium.

We are given:

A metal is placed in a freezer (cold object) and another metal is placed in an oven (hot object) and then both the metals are placed in boiling water.

Initially, the heat will flow from the boiling water (hot object) into the frozen metal (cold object) to maintain equilibrium

Hence, the correct answer is heat will flow from the boiling water into the frozen metal.
