For all the reactions listed, the moles of products and limiting reactants are;

1. Molar cofficient - 6, oxygen is the limiting reactant

2. Molar coefficient - 8 chlorine is the limiting reactant

3. Molar coefficient - 4 and CO2 is the limiting reactant

<h3>What is a chemical reaction?</h3>

A chemical reaction is a combination of reactants that yields products. Recall that the limiting reactant is the reactant that nis present in the least amount.

Let us now complete each reaction;

1. The molar coefficient of the product in reaction 1 is 6 and oxygen is the limiting reactant

2. The molar For all the reactions listed coefficent of the product in reaction 2 is 8 and chlorine is the limiting reactant

3. The molar coefficient of the product in reaction 3 is 4 and the limiting reactant is CO2.

What best describes why hair gel is considered a noncrystalline solid?
ad-work [718]

Given what we know, we can confirm that hair gel is considered a noncrystalline solid due to Atoms in the hair gel having no particular order or pattern.

<h3>What is a noncrystalline solid?</h3>
  • This is a solid whose atoms are amorphous.
  • What this means is that the atoms lack a specific order like most solids.
  • The most common example of this is glass.

Therefore, given the definition of a noncrystalline solid as a solid whose atoms lack a specified order, we can confirm that the second option which states that "Atoms in the hair gel having no particular order or pattern" is correct.

A bag of fertilizer is labeled 10-20-20. What is the actual percentage of phosphorus in the fertilizer?
aleksandr82 [10.1K]

Answer:

20% of phosphorus

Explanation:

A fertilizer is used to improve the fertility of soils. Most fertilizers contains the element nitrogen, phosphorus and potassium.

They are often designated NPK fertilizers.

  Now we know that the numbers 10-20-20 depicts the nitrogen-phosphorus and potassium content of the fertilizer.

From the designation,

    The actual percentage is 20% of phosphorus.

                                               10%  of nitrogen

                                                20% of potassium

Using the following reaction:
Romashka-Z-Leto [24]

Answer:

Mn is the oxidizing agent.

N is the reducing agent.

Explanation:

Hello!

In this case, according to the undergoing chemical reaction, it is seen that the manganese in KMnO4 has an oxidation state of 7+, in MnSO4 of 2+ and nitrogen in KNO2 is 3+ and in KNO3 is 5+; thus we have the following half-reactions:

Mn^{7+}+5e^-\rightarrow Mn^{2+}\\\\N^{3+}\rightarrow N^{5+}+2e^-

Thus, since manganese is undergoing a decrease in the oxidation state, we infer it is the oxidizing agent whereas nitrogen, undergoing an increase in the oxidation state is the reducing agent.

Best regards!

Which statement best describes what happens when thermal energy of the
vitfil [10]

When the thermal energy of the air around a fire is transferred to the surrounding air  A. The thermal energy is spread out by the surrounding air.

Thermal energy transfers occur in 3 approaches conduction, convection, and radiation. whilst thermal power is transferred among neighboring molecules that are in touch with each other, which is referred to as conduction.

Thermal strength refers to the power contained inside a system that is liable for its temperature. heat is the go with the flow of thermal electricity. an entire department of physics, thermodynamics, offers how heat is transferred among exceptional systems and how work is accomplished in the manner.

Thermal strength also referred to as heat strength is produced when a rise in temperature reasons atoms and molecules to transport quicker and collide with each other. The energy that comes from the temperature of the heated substance is referred to as thermal strength.
