Why are peroxide ions dangerous to cells?
Peroxide ions are dangerous to cells because they can generate reactive oxygen species (ROS) that can damage cell structures such as proteins, lipids, and DNA. This oxidative stress can lead to cell membrane disruption, impaired cellular functions, and ultimately cell death.
What is more corrosive Sulfuric acid or Carbonic acid?
The "corrosiveness" of an acid depends mainly on two aspectsThe concentration of the acid - even the most corrosive acid is not dangerous at low concentrations e.g. 0.001 mol/LThe % ionisation of the acid - This determines whether the acid is a strong acid (100% ionisation of the first H+ atom) or a weak acid (significantly less than 100% ionisation of the first H+ atom) Sulfuric acids first ionisation H2SO4 + H2O ==> HSO4- + H3O+Carbonic Acids first H2CO3 + H2O HCO3- + H3O+With this information, and the fact that we know sulfuric acid is a strong acid and carbonic acid is a weak acid, sulfuric acid is more corrosive than carbonic acid (at the same concentration
How does low ionisation energy favor the formation of ionic bond?
Ionisation energy is defined as the amount of energy required to remove the most loosley bound or valence electron from an atom. The lower the ionisation energy, the easier it is to remove the electron. Once the electron has been removed, electroneutrality is lost and the atom develops a positive charge and is known as a positively charged ion. Now, an ionic bond is the bond formed between two oppositely charged species. For example, a bond between a positively charges sodium ion and a negatively charged chloride ion. The lower the ionisation energy, the easier it will be for the atom to lose an electron, thereby forming a positively charged species which will be capable of forming an ionic bond with a negatively charged species. Or lower the ionisation energy, the greater is the tendency to form an ionic bond.
Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential
Why is plutonium-238 dangerous to the body?
Plutonium-238 is dangerous to the body because it is a radioactive metal that emits alpha particles, which can damage living cells and tissues when it comes into contact with them. Exposure to plutonium-238 can lead to long-term health effects such as radiation sickness, cancer, and increased risk of genetic mutations.
Are goblet cells dangerous?
Goblet cells are not dangerous; they are a normal part of human anatomy.
Are cancer cells dangerous?
Yes cancer cells are dangerous. Malignant cancer cells are the most dangerous as they can replicate and move to different parts of the body. Benign cancer cells are far less dangerous and don't replicate or move around the body.
How can you relate ionisation potential and ionisation energy?
Ionisation potential and ionisation energy are essentially the same concept - they both refer to the amount of energy required to remove an electron from an atom or molecule. The terms are often used interchangeably in practice.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Is pus cells is 2 to 4 is dangerous?
no
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
Why is using a virus to change a cells DNA dangerous?
DNA change/ mutations can be dangerous
When does a virus become dangerous?
when it conncets to the cells in your body
Who ionisation energy differs?
Ionisation energy differs between elements due to variations in the number of protons in their nucleus, which affects the strength of the attraction between the electrons and the nucleus. Elements with higher atomic numbers typically have higher ionisation energies due to increased nuclear charge. Additionally, ionisation energy generally increases across a period and decreases down a group on the periodic table.
What is better chlorine or ionisation system?
ionisation system stay in water whereas chlorine evaporate into the air, Chlorine irritates the skin, the eyes, and the respiratory system.
When does ionisation energy increases?
when we go from left to right
Do gasses have to be hot for ionisation to take place?
Yes.
