Answer:
1. ions
2. ions
Explanation:
Metals lose electrons and form positive ions (because there are more protons+)
While non-metals gain electrons and form negative ions.(more electrons-)

Answer:
A strong alkali is 100% ionised.eg÷sodium hydroxide.
A week alkali is not 100% ionised.eg÷ammonia
A concentrated acid contains a large amount of acid in a given volume.
The reaction between oxygen, O2, and hydrogen, H2, to produce water can be expressed as,
2H2 + O2 --> 2H2O
The masses of each of the reactants are calculated below.
2H2 = 4(1.01 g) = 4.04 g
O2 = 2(16 g) = 32 g
Given 1.22 grams of oxygen, we determine the mass of hydrogen needed.
(1.22 g O2)(4.04 g H2 / 32 g O2) = 0.154 g of O2
Since there are 1.05 grams of O2 then, the limiting reactant is 1.22 grams of oxygen.
<em>Answer: 1.22 g of oxygen</em>
