How many double bonds are in an alkane?
Answers
Alkanes only have single bonds
Final answer:
Alkanes are hydrocarbons with only single bonds between the carbon atoms, therefore, they do not contain any double bonds.
Explanation:
In chemistry, an alkane is a type of hydrocarbon where all of the carbon-carbon bonds are single bonds, meaning they share just one pair of electrons. Double bonds share two pairs of electrons and are typically found in alkenes, a different type of hydrocarbon. Therefore, an alkane does not have any double bonds.

Suppose you are digging a hole in the ground. You notice that the soil is in two layers. Each layer has particles of different sizes. You observe the soil closely and find that the bottom layer is made up mostly of sand and the top layer is made up mostly of clay. What do you think caused the soil to have two different layers?

The pressure inside the flask on heating it is given as 1.21 atm.
Explanation:
As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.
So P ∝ T
To convert celsius to kelvin, add 273.15 to the temperature value in celsius
Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as
So, the pressure inside the flask on heating it is given as 1.21 atm.
Final answer:
Using Gay-Lussac's law, the final pressure of the gas in the flask after heating from 24°C to 104°C, under a constant volume, is approximately 1.2 atm.
Explanation:
The pressure inside the flask can be calculated by using Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its absolute temperature, as long as volume is constant. This is formally expressed as P1/T1 = P2/T2, where P is pressure, T is absolute temperature (in Kelvin), and the subscripts refer to initial and final states.
First, convert the Celsius temperatures to Kelvin by adding 273.15 to the Celsius temperature. T1 = 24°C + 273.15 = 297.15 K, and T2 = 104°C + 273.15 = 377.15 K. Next, rearrange the equation to solve for P2: P2 = P1 (T2 / T1).
So, P2 = 0.95 atm * (377.15 K / 297.15 K) ≈ 1.2 atm. Therefore, the pressure inside the glass laboratory flask after heating to 104°C would be approximately 1.2 atm.

Answer:
Viscosity of water decreases markedly with increasing temperature. When the viscosity decreases, the flow resistance decreases. So for the same driving force, that is the pressure drop per unit length, the water flow rate will be higher.

B. electrons than protons
C. neutrons than protons

Final answer:
A positive ion, also known as a cation, has more protons than electrons as a result of losing electrons. For example, a sodium atom becomes a +1 sodium ion when it loses an electron. The number of neutrons does not affect the charge of ions.
Explanation:
A positive ion, also known as a cation, is formed when an atom loses one or more electrons. This causes the atom to have more protons than electrons, thereby gaining a positive charge. So, the correct answer to your question is A. Protons than electrons.
For instance, when a sodium atom (which has 11 protons and 11 electrons) loses an electron, it becomes a sodium ion with a +1 charge, having 11 protons and only 10 electrons.
Neutrons are particles present in the nucleus of an atom that do not carry any charge. Hence, the number of neutrons doesn’t affect the charge of ions.

Final answer:
A positive ion, or a cation, has more protons than electrons because it forms by losing electrons. Therefore, it has a net positive charge. The number of protons and neutrons doesn't change during this process.
Explanation:
A positive ion, also known as a cation, is formed when an atom loses electrons. The loss of electrons results in the atom having more protons than electrons, and subsequently more positive charge than negative, hence the name positive ion. Therefore, the correct answer to your question is A. protons than electrons. However, it’s important to note that the number of protons and neutrons in an atom does not change during chemical reactions or during the formation of ions.
