La nomenclatura química de H3PO4 es Ácido fosfórico
Or in English
Phosphoric acid
Answer:
It's the first option.
Explanation:
The atomic number tells us the number of protons in the nucleus of an atom.
It is the number which identifies an atom.
It will sink because it is heavier than the water.
there are <u>4 </u>grams of product produced by the chemical reaction
The Question is incomplete here is the complete question " Suppose an iron atom in the oxidation state +3 formed a complex with three hydroxide anions and three water molecules. Write the chemical formula of this complex.
Answer:
{Fe(OH)3(H20)3}
Explanation:
Oxidation state is the electron gained or lost by and atom, So if iron is in +3 state in formula it must have lost three electron.
We know that OH posses the oxidation state of -1 and water have zero oxidation state. SO, Let's take iron equal to y and find its oxidation state in the formula
y + 3 ( - 1 ) + 3 ( 0 ) = 0
y - 3 + 0 = 0
y-3=0
y= + 3
Hence it's proved that iron has +3 oxygen state.
