Answer:
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
Explanation:
The principle of writing balanced chemical reaction equations states that; the number of atoms of each element on the right hand side of the reaction equation must be equal to the number of atoms of the same element on the left hand side of the reaction equation.
The reaction is between aqueous aluminum phosphate reacts and solid magnesium to produce solid aluminum and aqueous magnesium phosphate. The equation is represented as follows;
2AlPO4(aq) + 3Mg(s) -------> Mg3(PO4)2(aq) + 2Al(s)
I believe the correct answer from the choices listed above is the third option. The ion would be Al+3. It is obvious because among the options, this is the only substance that has a charge. <span>An </span>ion<span> is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. </span>
Answer:
CaC2 + 2H20 ⇋Ca(OH)2 + C2H2
Explanation:
CaC2 + A H20 ---> Ca(OH)2 + A C2H2
This is calcium carbide reacting with water to produce calcium hydroxide and ethyne commonly called acetylene.
Let's now balance the equation.
CaC2 + 2H20 ⇋Ca(OH)2 + C2H2
Answer:
1) Mendeleev's periodic table grouped elements on the basis of their atomic masses, while the modern periodic table groups elements on the basis of atomic number.
2) As we know, the isotopes of an element will have the same atomic number. This is because there number of protons will be same. Hence, in the modern periodic table the isotopes of an element share the same place.
3) Cobalt is places on the 9th position and nickel on the 10th position. There were arguments before as the atomic mass of nickel was more than cobalt.
4) A position for the hydrogen atom was finally allocated in the modern periodic table which had been a issue in Mendeleev's periodic table. Hydrogen is placed on top of the alkali metals i.e the first group.
