Answer:
Option : KBr + I -> KBr+I
Explanation:
Single-replacement reaction or single displacement reactions are a type of chemical reactions in which a whole compound reacts with an element in such a way that the element takes place of one of the compound's own elements and sets it free.
If we talk about KBr and I displacement reaction is not possible among these because Iodine is less reactive than Bromine that is why it will not react with KBr or replace Br.
KBr + I -> KBr+ I
Potassium Bromide + Iodine -> Potassium bromide + Iodine
Hope it help!
Answer:
Fe + CuO ----> FeO+ Cu
Explanation:
A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.
Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.
The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.
O valence electron number is the answer
Answer:
V₂ = 2509.62 cm³
Explanation:
Given data:
Initial volume = 1500 cm³
Initial temperature = -65°C (-65 + 273 = 208 K)
Final temperature = 75°C ( 75 +273 = 348 K)
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 1500 cm³ × 348 K / 208 k
V₂ = 522000 cm³.K / 208 k
V₂ = 2509.62 cm³
This process is called aerobic respiration.
