While metallic bonds have the strong electrostatic force of attractions between the cation or atoms and the delocalized electrons in the geometrical arrangement of the two metals. ... Metallic bonds are malleable and ductile, while covalent bonds and ionic bonds non-malleable and non-ductile.
Answer:
wavelength.. meter
frequency.... Hertz (cycle per second)
energy.... Joule
Answer:
M₁ = 0.178 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid,
M₂ = concentration of base ,
V₂ = volume of base,
from , the question ,
M₁ = ?
V₁ = 20.0 mL
M₂ = 0.158 M
V₂ = 22.60 mL
Using the above formula , the molarity of the acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 20.0 mL = 0.158 M * 22.60 mL
M₁ = 0.178 M
The oxidation number of hydrogen in H2 reactant will be 0.
The number assigned to each element in a chemical combination would be the simplest definition of the oxidation number. The amount of electrons that atoms in a molecule could share, lose or gain during forming chemical connections with other atoms of such a particular character would be known as the oxidation number.
Hydrogen can be considered as free elements and it is known that free elements have 0 oxidation number .Here, H2 element is also as a free element. So, it has 0 oxidation number.

When any alkane burns with a sufficient oxygen supply, carbon dioxide and water will be produced. Because butane is an alkane, the reaction would look like this:
2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
