What compound is O2H?
Answers
The answer is:
O2H is a reactive oxygen species (ROS).
The explanation is:
It is known by different chemical names like:
- Dioxidanide, Oxylatooxygen, HOO anion, hydroperoxyl, Hydrogen dioxide (1-), Hydrogen peroxide (1-), etc.
- ROS show antimicrobial activity, so they can be used as antibiotics.
- O2H is also manufactured as a bacteriostatic antibiotic.
-It is generally available in tablet form.
- It is used in the treatment of many gram-positive and gram-negative bacterial infections, like infections of the skin, eye, lungs (bronchitis), urinary tract, bladder, pelvis, etc. (Note: A bacteriostatic antibiotic is one which damages bacterial DNA. Bacterial replication is hindered, so bacterial infection is combatted).
Answer:
O₂H is Reactive Oxygen Species (ROS)
Explanation:
O₂H has many names including:
1- hydroperoxyl
2- Oxylatooxygen
3- Dioxidanide
4- Hydrogen dioxide or Hydrogen peroxide
This compound exists in stable form only in the aqueous state and is formed by the equation shown in the attached picture.
This compound is used mainly in the manufacture of bacteriostatic antibiotics. This is because it can damage the DNA of the bacteria which leads to the termination of its replication and thus, it can be combated.
Hope this helps :)

Answer:
2522g
Explanation:
8Fe + S8 —> 8FeS
From the question,
8moles of Fe required 1mole of S8.
Therefore, Xmol of Fe will require 5.65mol of S8 i.e
Xmol of Fe = 8 x 5.65 = 45.2moles
Now we need to covert 45.2moles to gram. This is illustrated below below:
Molar Mass of Fe = 55.8g/mol
Number of mole of Fe = 45.2moles
Mass of Fe =?
Mass = number of mole x molar Mass
Mass of Fe = 45.2 x 55.8
Mass of Fe = 2522g
Therefore, 2522g of Fe is needed for the reaction.

he thought that atoms were the smallest particle and could not be divided any more. the word 'atomos' which atom is derived from, means indivisible. we now know that atoms are made of sub-atomic particles, which are made of quarks (what sort of name is that), and these quarks are made of leptons and gluons.
Final answer:
Democritus's ideas about atoms were limited in that he claimed they were indivisible and indestructible, lacked experimental evidence, and didn't account for chemical behavior or atomic bonding.
Explanation:
Democritus, an Ancient Greek philosopher, made significant strides in atomic theory. However, his ideas had several limitations. Firstly, he believed that atoms were indivisible and indestructible, which we now know is incorrect, with subatomic particles like protons, neutrons, and electrons forming atoms. Secondly, Democritus had no experimental evidence to support his ideas, they were purely philosophical. Lastly, his theory did not account for chemical behavior or the bonding of atoms, concepts that are now fundamental to our understanding of chemistry.

Answer: gasoline
Explanation:
An aqueous solution is one which contains water as a solvent. A non- aqueous solution is the one in which the solvent of the solution is a liquid but it is not water.
Among the options given, gasoline is the correct option. This is because of the fact that gasoline is a crude oil which does not include water as an ingredient.

Answer:
-232 °C
Explanation:
We can use the Ideal Gas Law and solve for T.
pV = nRT
Data:
m = 20.0 g
p = 6.0 atm
V = 0.40 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
Calculations:
1. Moles of N₂
2. Temperature of N₂
3. Convert the temperature to Celsius
T = (41.0 - 273.15) °C = -232 °C

Answer:
0.172 mol·L⁻¹
Step-by-step explanation:
1. Write the chemical equation for the reaction.
HBr + LiOH ⟶ LiBr + H₂O
===============
2. Calculate the moles of LiOH
c = n/V Multiply each side by V
n = Vc
V = 0.0375 L
c = 0.215 mol·L⁻¹
Moles of LiOH = 0.0375× 0.215
Moles of LiOH = 8.062 × 10⁻³ mol LiOH
===============
3. Calculate the moles of HBr
1 mol HBr ≡ 1 mol LiOH
Moles of HBr = 8.062 × 10⁻³× 1/1
Moles of HBr = 8.062 × 10⁻³ mol HBr
===============
4. Calculate the molar concentration of the HBr
V = 47.0 mL = 0.0470 L
c = 8.062 × 10⁻³/0.0470
c = 0.172 mol·L⁻¹
The molarity of the HBr solution is 0,172 M.
The neutralization reaction between LiOH and HBr is the following:
HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)
