Mole is equal to 6.02*10^23 atoms, and you have 7.00*10^23 atoms
Oxidation number of an atom is the charge that atom would have if the compound is composed of ions. In neutral substances that contains atoms of one element the oxidation number of an atom is zero. Thus atoms in O2, Ni2, and aluminium all have oxidation number of zero.
In this case, Ni2, the oxidation number of Ni atom is zero,
for NiO4-, assuming oxidation number of Ni is x
(x ×1) + (-2 × 4) = -1
x = + 7
Therefore, the oxidation number goes from 0 to +7
The cytoplasm slides and forms a pseudopodium in front to move the cell forwards.
I suppose it would be forest because in order to have organic matter the soil needs to be rich and fertile,therefore it is forest.
Carbon is found in oil and gas.
Aluminum a light metal used in making pots and pans.
Bromine is used in photography.
