Answer:

Heating of the liquid water in a microwave.

Explanation:

Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed.  Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.

Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.

From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.

Step 1: Define

[RxN - Balanced] C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

[Given] 150 g O₂

Step 2: Identify Conversions

[RxN] 5 mol O₂ → 3 mol CO₂

[PT] Molar Mass of O - 16.00 g/mol

[PT] Molar Mass of C - 12.01 g/mol

Molar Mass of O₂ - 2(16.00) = 32.00 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

In first place, the balanced reaction is:

4 NH₃ + 3 O₂  → 2 N₂+ 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?

[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]

mass of N₂= 56.42 grams

Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

The molecular formula for Neon is Ne. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Neon, or 20.1797 grams.

Answer: 8 Moles of Oxygen

Explanation: The formula shows that there are (exactly) 4 oxygen atoms in each mole or formula unit. Therefore 4 * 2.00 = 8.

Answer:

13.25 ×10²³ atoms

Explanation:

Given data:

Mass of NaCl = 128 g

Number of atoms = ?

Solution:

First of all we will calculate the number of moles of NaCl.

Number of moles = mass/molar mass

Number of moles = 128 g/ 58.4 g/mol

Number of moles = 2.2 mol

Number of atoms:

1 mole of any substance contain 6.022×10²³ atoms.

2.2 mol × 6.022×10²³ atoms / 1mol

13.25 ×10²³ atoms

The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

1 mole is equal to 6.023 × 10 ²³ molecules.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.

Thus, option A is correct.
