Answer:
C. Al
Explanation:
2Al+ 3H2SO4(l)------> Al2(SO4)3+ 3H2
They have similar properties because they have the same number of valence electrons
The electron B. is the smallest part of an atom.
Answer: A. 1,1,1
Explanation:
The coefficients that will balance the equation; NH4OH(aq) →H2O(l) + NH3(g), is 1, 1, 1, because it proves the total number of atoms of each element on the LHS and RHS of the equation are equal, hence balanced.
LHS RHS
N = 1 1
H = 5 5
O = 1 1
B.Ag from the latin Argentum
