Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.

Answer: 59 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of hydrogen = 6.6 g
mass of oxygen = 52.4 g
Mass of products = Mass of hydrogen + mass of oxygen = 6.6 +52.4 = 59 g grams
Thus mass or reactant = mass of water
Mass of reactants = mass of products = 59 g
Thus the mass of water initially present was 59 g.
Molarity is expressed as
the number of moles of solute per volume of the solution. The mass of oxalic acid dihydrate needed for the solution is calculated as follows:
Amount in moles: (0.357 mol H2C2O4•2H2O / L) (.250 L ) = 0.0893 mol H2C2O4•2H2O
Amount in mass : 0.0893 mol H2C2O4•2H2O (126.08 g / mol ) = 11.2589 g H2C2O4•2H2O
Hope this answers the question. Have a nice day.
Answer: Through extensive bonding
Explanation:
Oxidation of two cysteine gives disulphide bonds. They are covalent in nature. Given as;
R-CH2-SH + R'-CH2 +02 = R-CH2-S-S-CH2-R' + H202
They are the stabilizing force behind protein folding the endoplasmic reticulum. Proteins being the backbone of our genetic constitution require disulphide bonding to stabilize the peptide molecules and the extent and number of this bonding determines the Resistance of the protein molecule to extreme conditions e.g extreme heat which denatures proteins and elasticity as well.
There are 236 grams in 5.9 mole of NaOH.
