Answer:
Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.
Explanation:
the axis is vertical
Answer:
a.substitution
Explanation:
because one of the hydrogen atoms from the methane is replaced with a bromine atom.Alkanes undergo a substitution reaction with halogens in the presence of light. For example, in ultraviolet light , methane reacts with halogen molecules such as chlorine and bromine. This is a substitution reaction because one of the hydrogen atoms from the methane is replaced by a bromine atom.
If we consider the reaction CH₃O⁻ + H₂O ⇌ CH₃OH + OH⁻ in the forward direction, the base in the reaction is CH₃O⁻
A compound can be acidic, basic or neutral in nature. Basicity of the compound is determined when it either releases hydroxide ions, donates electrons or else accepts the protons from a compound.
In the reaction CH₃O⁻ + H₂O ⇌ CH₃OH + OH⁻:
CH₃O⁻ accepts proton or [H+] ion to become CH₃OH. Thus, CH₃O⁻ is the base in the reaction
H₂O donate [H+] ion or proton, therefore H2O change into OH-. Thus, H₂O is an acid in the reaction.

Explanation:
it was first recorded by England's Sir Francis Bacon (1561-1626)
Answer:
CaBr2 is a colorless solid and the charge on Calcium is +2
Explanation:
CaBr2 is a colorless solid at room temperature.
Other properties include -
a) It is a crystalline solid
b) Melting point of 765°C.
c) It is deliquescent
d) Soluble in water and absolute alcohol.
The charge of Br is -1. Here two atoms of Br attaches with one atom of calcium. Hence the charge of calcium is +2
