how many atp are produced by lactic acid fermentation?
Two atp are produced by the fermentation of lactic acid. One glucose molecule undergoes fermentation, producing one ATP molecule. Actually, fermentation does not produce ATP.
NAD+ is refilled for glycolysis by converting pyruvate to lactic acid or ethyl alcohol during fermentation. Keep in mind that during glycolysis, a glucose molecule is broken down into two pyruvate molecules, resulting in the production of two ATP and two NADH molecules. When you work out your muscles quickly and furiously, your own muscle cells start lactic acid fermentation, an anaerobic respiration process akin to what yoghurt bacteria do (Lactobacillus and others). Lactic acid is frequently fermented by anaerobic bacteria and yeast. The recipes for fermentation of lactic acid.

How many atoms are in 3.05 moles of CH4?
There are 18.3 x 10^23 atoms in 3.05 moles of CH4. Methane (CH4) is a hydrocarbon and the simplest and most common member of the alkane family of organic compounds.
Moles are a unit of measurement used in chemistry to express the amount of a substance. The Avogadro constant, which is the number of atoms or molecules per mole, is 6.022 x 10^23.
To find the number of atoms in a given number of moles, you can use the formula:
n = N x N_A
where n is the number of atoms, N is the number of moles, and N_A is the Avogadro constant.
In the case of CH4, it is composed of 1 carbon atom and 4 hydrogen atoms per molecule.
So, to find the number of atoms in 3.05 moles of CH4, you can plug in the values into the formula:
n = 3.05 x 6.022 x 10^23
n = 18.3 x 10^23 atoms
Therefore, there are 18.3 x 10^23 atoms in 3.05 moles of CH4.

Use the electron-transfer method to balance the equation involving the reaction of lithium with water to produce lithium hydroxide and hydrogen gas.
Answer:
Explanation:
The equation for the reaction of lithium with water to produce lithium hydroxide and hydrogen gas is:
Li + H2O -> LiOH + H2
To balance this equation using the electron-transfer method, we first need to determine the oxidation states of each element in the reactants and products.
In Li, the oxidation state of lithium is +1. In H2O, the oxidation state of hydrogen is +1 and oxygen is -2.
In LiOH, the oxidation state of lithium is +1, oxygen is -2 and hydrogen is +1.
In H2, the oxidation state of hydrogen is +1.
It's clear that lithium loses 1 electron to become Li+ and hydrogen gains 1 electron to become H-.
So, we have to add an electron on the right side of the equation to balance the electrons.
Li + H2O -> LiOH + H2 + e-
Now, the number of electrons on both sides of the equation is the same and the equation is balanced.
Alternatively, we can use the oxidation number method, where we balance the charge of the reactant and product side of the equation. The sum of the oxidation numbers of all atoms on the reactant side must equal the sum of the oxidation numbers of all atoms on the products side. In this case, the oxidation state of lithium is +1, hydrogen is +1 and oxygen is -2.
Li + H2O -> LiOH + H2
+1 +1 -2 = +1 +1 +1 -2
The equation is already balanced with respect to oxidation numbers

Hydrogen is the element with the lowest density in the periodic table and exists as a gas and osmium is the element with the highest density.
Define lowest density?
If the particles are loosely packed together with plenty of space between them, it will have a low density and will be able to float. And if the particles are tightly packed together with no or very little space between the particles, it will have higher density. This is so because if we divide each object's mass by its volume, and since all three objects have the same volume, the object with the larger mass will have the greatest density. And the object with the smaller mass, will have the lowest density.Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity. When water freezes at 0°C, a rigid open lattice (like a web) of hydrogen-bonded molecules is formed.

The carbonyl peak wavenumber shifts to the left by 30 in a conjugated system compared to a non-conjugated one.
In an IR spectroscopy, the carbonyl peak is characterized by a strong absorption band between 1710-1730 cm-1. The carbonyl peak is due to the stretching of the C=O bond. In non-conjugated systems, the carbonyl peak has a wavenumber of 1710-1730 cm-1, but in conjugated systems, the peak shifts to the left by 30 cm-1 to a wavenumber of 1680-1700 cm-1. The reason for this shift is that in conjugated systems, the carbonyl group is delocalized, meaning that the electrons in the carbonyl double bond are spread out over a larger area. This delocalization reduces the strength of the C=O bond and causes the peak to shift to the left. This shift allows to distinguish between a non-conjugated and conjugated carbonyl compound.
