Answer: D
Explanation:
the atom of the metal loses one electron which becomes delocalised and is attragted by the positive nucleus leading to formation of metallic bond.
Answer:
2HBr + Mg(OH)2 => MgBr2 + 2 H2O
Explanation: To balance the equation put 2 in H2O in the product side. Then balance the other Hydrogen atoms by adding 2 in HBr. Since there is another 2 atoms of H in (OH)2 so hydrogen atoms are balanced having 4 atoms each sides. Also Mg and Br are balanced
Answer:
4 p and 10 O on both sides
Explanation:
on the reactant side you can see easily that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.
On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O
They are equal on both sides so you are done.
