Answer:
0.643 mol.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm (P = 4.0 atm).
V is the volume of the gas in L (V = 4000 mL = 4.0 L).
n is the no. of moles of the gas in mol (n = ??? mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 30ºC + 273 = 303 K).
∴ n = PV/RT = (4.0 atm)(4.0 L)/(0.0821 L.atm/mol.K)(303 K) = 0.643 mol.

Answer:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.
The reaction completely follow the law of conservation of mass because there are equal number of atoms of each elements on both side of equation.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Metabolism refers to all of the chemical reactions occurring in the body cells of an organism for life sustenance. This includes synthesis processes such as:
- building a larger molecule from many smaller ones e.g. protein builds up from amino acids,
- breaking down of larger molecules into bits and smaller ones e.g.as seen in digestive reactions, and respiratory reactions.
When metabolic activities take place, there is a release of energy in the process. This energy is stored in a form of a covalent bond, a particular type of chemical bond.
On the other hand, a chemical bond is the creation of a chemical compound by forming a chemical connection between two or several more atoms, ions, or molecules.
Chemical bonds between atoms and molecules must be broken and reformed, therefore rendering chemical bonding an important element of metabolism.
Therefore, we can conclude that chemical bonds are important and a crucial part of metabolism because for metabolism to occur, Chemical bonds between atoms and molecules must be broken and reformed.

Answers
Answer:
Explanation:
The half reactions are:
Mg → Mg²⁺
+ 2e⁻
2H⁺ + 2e⁻ → H₂
The first equation is an oxidation half while the second is a reduction half. To get the overall reaction equation, we simply combine the two equations. The reactants combines at the left hand side with the products comes together at the right hand side.
Mg + 2H⁺
+ 2e⁻ → Mg²⁺
+ 2e⁻ + H₂
Now we cancel out the species that appear on both sides:
Mg + 2H⁺
→ Mg²⁺
+ H₂

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 :)
