I found this information:
Anaerobic respiration begins the same way as fermentation. The first step is still glycolysis, and it still creates 2 ATP from one carbohydrate molecule. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration.
After making a molecule called acetyl coenzyme A, it continues to the citric acid cycle. More electron carriers are made and then everything ends up at the electron transport chain. The electron carriers deposit the electrons at the beginning of the chain and then, through a process called chemiosmosis, produce many ATP. For the electron transport chain to continue working, there must be a final electron acceptor. If that acceptor is oxygen, the process is considered aerobic respiration.
Scientists believe that fermentation and anaerobic respiration are older processes than aerobic respiration.
I hope this help. :)
have a good day!
Answer:
calcium hydroxide
lithium phosphate
ammonium sulfide
AgNO3
Explanation:
A polyatomic ion refers to an ion composed of two or more atoms in the ion. In the compounds mentioned, each contains at least one poly atomic ion.
AgNO3 contains NO3^- as its polyatomic ion
calcium hydroxide contains OH^- as its polyatomic ion
lithium phosphate contains PO4^- as its polyatomic ion
ammonium sulfide contains NH4^+ as its polyatomic ion.
It is determined by its ELECTRIC CONFIGURATION.
Answer:
150 g/mol
Explanation:
Let's consider the complete neutralization of a diprotic acid H₂X with NaOH.
H₂X + 2 NaOH → Na₂X + 2 H₂O
40.0 mL of 0.200 M NaOH. were required to reach the endpoint. The reacting moles of NaOH are:
0.0400 L × 0.200 mol/L = 8.00 × 10⁻³ mol
The molar ratio of H₂X to NaOH is 1:2. The reacting moles of H₂X are 1/2 × 8.00 × 10⁻³ mol = 4.00 × 10⁻³ mol.
4.00 × 10⁻³ moles of H₂X have a mass of 0.600 g. The molar mass of H₂X is:
0.600 g/4.00 × 10⁻³ mol = 150 g/mol
