Oxygen has an oxidation state of -2 so considering that there are 2 oxygen atoms,
2 x -2 = -4
The compound is neutrally charged so the sum of all the oxidation states must be zero. Therefore the oxidation state of Ge must be +4 in order to cancel the -4 to make zero.
Reduction. KMnO4 is an oxidizing agent(oxidizes substances) Therefore it is reduced. The MnO4-(purple colour) from the KMnO4 is reduced to Mn2+(pale pink/ colourless).
Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di-is of Greek origin, meaning "two". If a diatomic molecule consists of two atoms of the same element such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear.

Answer:
rebar
is gridwork of steel rods
Explanation:
Reinforced concrete is one important component of skyscrapers. It consists of concrete (a mixture of water, cement powder, and aggregate consisting of gravel or sand) poured around a gridwork of steel rods (called rebar) that will strengthen the dried concrete against bending motion caused by the wind.
