Answer:

Atoms of every element are shown in a skeletal model of an organic molecule.

Explanation:

Skeletal model of an organic molecule consists of various skeletal atoms that are used in making up of the molecule. Various conventions of  hydrogen and  carbon  atoms are employed in it. The molecules bonding and certain representation of molecular geometry are shown in the structural formula.

Use of skeletal formula is ubiquitous in organic chemistry. Thus, in organic chemistry atoms of every element are shown in the skeletal model of an organic molecule

Here we have to point out the necessary character of the substance needed which are used as lightning conductor.  

The substance should have the following properties:

High electricity carrying capacity and less resistant.

High melting point

The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground  

The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.

Answer:The lightning rod should be constructed of a metal, which is an inorganic substance.

Metals are good conductors of electricity.

Explanation:

We are required to explain the meaning of volume and mention the instrument used to measure liquid volume.

• Volume refers to the unit of three-dimensional measure of space that comprises of a length, a width and a height. It is measured in units of cubic centimeters(cm³), cubic inches(in³) or cubic feet(ft³).

• An instrument used to measure liquid volume is called a graduated cylinder or a buret.

Since, volume comprises of length, width and height, then the formula used to calculate the volume of a solid object is length multiplied by width multiplied by height.

Therefore,

Volume of a solid object = Length × Width × Height

Answer:

Volume is the amount of space that a substance occupies. A graduated cylinder is used to measure liquid volume. The formula used to calculate the volume of a solid object is = L x W x H

Answer:

The number of atom is 3.67*10^24 atoms

Explanation:

Molar mass of methane CH4 is 16.0g/mol

Using this to divide the mass

24.4g/16.0 = 1.525mol

1 mol CH4 contains 1 mol of Carbon C and 4 mol of hydrogen H, so 1.525mol contains 4(1.525)=6.1 molH

Using avogadro number : (6.1mol)(6.02*10^23)

= 3.67*10^24 atoms

Final answer:

There are 3.66 × 10^24 hydrogen atoms in 24.4 g of methane (CH4). This is calculated by first finding the number of moles of CH4 and then using Avogadro's number to determine the total number of molecules, which is finally multiplied by 4 (the number of hydrogen atoms per CH4 molecule).

Explanation:

The question asks how many atoms of hydrogen are in 24.4 g of methane (CH4). Methane has a molecular formula of CH4, indicating that each molecule contains 4 hydrogen atoms. The molar mass of methane is 16.04 g/mol (12.01 g for carbon + 4 × 1.008 g for hydrogen).

First, calculate the number of moles of methane:

24.4 g CH4 × (1 mol CH4 / 16.04 g CH4) = 1.52 mol CH4

Then, multiply by Avogadro's number to find the total number of methane molecules:

1.52 mol CH4 × (6.022 × 1023 molecules/mol) = 9.15 × 1023 molecules of CH4

Since each molecule of methane has 4 hydrogen atoms, we get:

9.15 × 1023 molecules CH4 × (4 H atoms/molecule) = 3.66 × 1024 hydrogen atoms.
