A.) AlO is the correct formula
Answer:
<h2>4. Sea water is a solution.</h2>
Explanation:
The solution is a type of homogenous mixture in which the solute is dissolved homogeneously in the water. Salt is dissolved in the seawater so the seawater is a type of solution. The salinity of the seawater is about 3.5 % that means about 35 grams of salts are dissolved per kilogram of the water. There are many ions or salts that are present in the seawater such as bicarbonate, sodium ins, chloride ions and some other.
Answer:
Al, Zn, Fe, Sn, Pb.
Explanation:
The arrangement can be done using the infomation on electrochemical series of metals.
The electrochemical series is built up by arranging various metals in order of their standard electrode potentials (or reactivity). The most negative E° values are placed at the top of the electrochemical series, and the most positive at the bottom. some of the metals are arranged as follws; K, Na, Ca, Mg, Al, Zn, Fe, Sn, Pb, H, Cu, Hg, Ag, Au (decreasing reactivity)
One can use the following to remember the arrangement: king Nathan Can Manage All Zone Freely Since Probably He Can Handle All Ages.
