Oxygen - nitrogen gas mixture is a colorless odorless gas. Both oxygen and nitrogen are noncombustible; however, oxygen can accelerate the burning of a fire. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
An example of an exothermic reaction will be formation of ice
Answer:
True is the correct answer.
Explanation:
- The statement that a prion is an infectious, self-reproducing protein structure is true.
- prion is an infectious particle and they do not have genetic material.
- Prion present in the brain region that results in deadly neurodegenerative illnesses in humans and animals.
- Prions are the self-producing proteinaceous infectious capable of transferring infection in the absence of the nucleic acids.
- prions enter in the brain by an infection and they emerge from the variation in the gene that encodes the protein and once the prions present in the brain multiply by causing the benign proteins to refold into an abnormal form.
Alkanes are hydrocarbons that only contain single bonds in them. A carbon can bond with up to 4 atoms, even with another carbon atom. So, in a C-C bond, 3 more H atoms can bond to each of the C atom. Generally, the chemical formula for alkanes is CₓH₂ₓ₊₂. So for butane, there are 4 C atoms. The corresponding H atoms are 2(4) + 2 = 10. That's why it's chemical formula is C₄H₁₀.
