Can someone help me find the theoretical value of methane? It is chemistry
Answers
Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxideand water vapour; the flame is pale, slightly luminous, and very hot.The boiling point of methane is −162 °C (−259.6 °F) and the meltingpoint is −182.5 °C (−296.5 °F). Methane in general is very stable, butmixtures of methane and air, with the methane content between 5 and 14percent by volume, are explosive. Explosions of such mixtures have beenfrequent in coal mines and collieries and have been the cause of manymine disasters.

Answer : The correct option is, (2)
Explanation :
Arrhenius theory : It sates that an acid is a type of substance that ionizes in the water to give the hydronium ion or hydrogen ion and a bases is a type of substance that ionizes in the water to give hydroxide ion
.
Or we can say that,
Arrhenius acid are those which can easily gives the hydrogen ion in a solution and Arrhenius base are those which can easily gives the hydroxide ion in a solution.
In option 1, can easily gives the hydrogen ion but
can not gives the hydrogen ion due to stronger O-H bonding. So, these formulas does not represent Arrhenius acids.
In option 2, and
can easily gives the hydrogen ion. So, these formulas represent Arrhenius acids.
In option 3, and
can not gives the hydrogen ion because both are the salts. So, these formulas does not represent Arrhenius acids.
In option 4, and
can not gives the hydrogen ion because no hydrogen present in the compound. So, these formulas does not represent Arrhenius acids.
Hence, (2) represent Arrhenius acids.

Explanation:
The plasma membrane is a structure that has several distinct roles in the cell
The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic
*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:
when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids
*Protein Molecules play an important role in transport system such as Carrier Proteins
*Cholesterol Molecules help in balancing the Fluidity of the plasma membrane

Now, diseases and such can be passed along to the child if there's a defect on the sex chromosomes, the only chromosomes that are passed to the child. A cut on the dad of the child wouldn't cause the child to be born with a cut since the sex chromosomes weren't affected.
Color blindness, on the other hand, is sex chromosome related and can be passed down to the child. Since the sex chromosomes tell the DNA how to grow and operate, there's a possibility that the chromosomes could tell the DNA to have color blindness put within the genes of the child since the parent(s) sex chromosomes have that.

60 ml of a 0.40 m solution of h2so4 is used to neutralize 0.3 m magnesium hydroxide solution, the volume of NaOH required to neutralize the given amount of Mg(OH)2 is 160 ml.
To answer this question, we need to use the concept of stoichiometry. Stoichiometry is the calculation of the quantities of reactants and products in a chemical reaction. The balanced chemical equation for the neutralization reaction between sulfuricacid (H2SO4) and magnesium hydroxide (Mg(OH)2) is:
H2SO4 + Mg(OH)2 → MgSO4 + 2H2O
From the equation, we can see that one mole of H2SO4 reacts with one mole of Mg(OH)2. Therefore, the number of moles of Mg(OH)2 in 60 ml of 0.3 m solution is:
moles of Mg(OH)2 = concentration x volume = 0.3 x (60/1000) = 0.018 moles
Since one mole of Mg(OH)2 requires one mole of NaOH to neutralize it, we need 0.018 moles of NaOH. The concentration of the NaOH solution is not given, so we cannot directly calculate the volume of NaOH required. However, we can use the concentration and volume of the H2SO4 solution to find the number of moles of H2SO4 used in the neutralization reaction:
moles of H2SO4 = concentration x volume = 0.40 x (60/1000) = 0.024 moles
From the balanced equation, we know that one mole of H2SO4 reacts with two moles of H2O. Therefore, the number of moles of H2O produced in the reaction is:
moles of H2O = 2 x moles of H2SO4 = 0.048 moles
Since the reaction is neutralization, the same number of moles of H2O and H+ ions are produced. Therefore, the number of moles of H+ ions produced is also 0.048 moles. Each mole of NaOH can neutralize one mole of H+ ions. Therefore, the number of moles of NaOH required is:
moles of NaOH = 0.048 moles
If we assume that the concentration of the NaOH solution is also 0.3 m, then the volume of NaOH required is:
volume of NaOH = moles of NaOH / concentration = 0.048 / 0.3 = 0.16 L = 160 ml
