Explanation:
Metals react with oxygen to form basic oxides while they react with water to form alkaline solutions. Also, acidic oxides are oxides of nonmetals and they react with water to form acidic solutions.
Trends on the period table shows the variation of metallic character as you move across and down the periodic table. Metallic character of a element decreases across the period on the periodic table from left to right because atoms readily accept electrons in their outermost shell to form stable configurations. Metallic character increases as you move down the group in the periodic table and this is because electrons become easier to lose as the atomic radius increases (more outer shells are added), where there is decreasing attraction between the nucleus and the valence electrons.
So down the group, the acidity of oxide reaction with water decreases because the oxides are more basic down the group while across the period, the acidity of oxide increases because acidic oxides are formed as we move across the period.
Answer:
Substance K is hydrochloric acid and the process is neutralisation
Step-by-step explanation:
When you react hydrochloric acid and sodium carbonate, you produce sodium chloride, carbon dioxide and water
Answer:
Cells need to maintain homeostasis in order for our body to be healthy and fully functional. If the internal conditions of our cells are not stable, then the normal cell functions would be disrupted.
Explanation:
V=LW/H
VH=LW
H=LW/V
That’s the answer
