Answer:
Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
The IUPAC names of the organic compounds would be as follows:
1. Methanol or 1-Methanol
2. Propan-2-ol or 2-Propanol
3. 2-MethylButane
4. 1-Hexanol
5. 1-Heptanol
<h3>Naming organic compounds</h3>
In the naming of organic compounds, some fundamental rules come into practice. Some of these rules include:
- The longest carbon chain, otherwise known as the parent chain, is considered.
- The substituents must be identified
- The parent chain should be named such that the substituents are located on the lowest-numbered carbons. Repeated substituents are named accordingly.
- Different substituents are named alphabetically and substituents with lower alphabets are considered for the lowest-numbered carbons.
Following these rules and more, the name of the organic compounds whose structures are shown in the image would be as follows:
- Methanol or 1-Methanol
- Propan-2-ol or 2-Propanol
- 2-MethylButane
- 1-Hexanol
- 1-Heptanol

The question in English is "<span>Determine the mass, in kg, of a material that is contained in a volume of 18L. It is known that the material density is 0.9 g/cm 3"
Answer:
</span>
We can use a simple
equation to solve this problem. <span>
d =
m/v</span><span>
<span>Where </span>d <span>is
the density, </span>m <span>is
the mass and </span>v is the volume.
d = </span>0.9<span> g/cm³
m = ?
v = </span>18 L = 18 x 10³ cm³<span>
By applying the equation,
<span> 0.9 g/cm³ = m / </span></span>18 x 10³ cm³<span>
m = 0.9 g/cm³ x </span>18 x 10³ cm³<span>
<span>
</span>m = 16200 g
m = 16.2 kg
Hence, the mass of
18 L of material is 16.2 kg.</span>
Answer:
The answer to your question is below.
Explanation:
1. Has 4 energy levels
<u>a. K </u><u>Potassium is in period 4 so it has four energy levels</u>
<u>b. Ga </u><u>Also Galium is located in period four, so it has four energy levels.</u>
c. Al Aluminum only has 3 energy levels.
<u>d. Ge </u><u>Germanium has four energy levels</u>
<u></u>
2. Tends to lose 3 electrons
a. K Potassium only lose one electron
<u>b. Ga </u><u>Gallium loses 3 electrons because is in group three.</u><u>
</u>
<u>c. Al </u><u>Aluminum loses 3 electrons</u>
d. Ge Germanium tends to gain or lose four electrons.
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
<h3>Determine hydronium ion concentration when pH = 7 </h3>
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
