Answer:
When the metal reacts with hot, concentrated sulphuric acid, the products of the reaction are copper (II) sulphate, sulphur dioxide and water. Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O. This is a typical redox reaction in which the acid is reduced to SO2, but no hydrogen is produced here
Cell replication in somatic cells is called mitosis.
Cell replication in gametes (sex cells) is called meiosis.
Answer:
OCl− + H2O ⇌ HOCl + OH−
Explanation:
Sodium hypochlorite is a corrosive base with pH 13, that will react with water in a neutralization process to finally obtein hypochlorous acid. This acid has a great disinfectant effect in water.
The answer to this question would be:
NCl3 is a molecular compound (two or more nonmetals), and therefore in its name prefixes indicate the number of each type of atom. so NCl3 is nitrogen trichloride<span>.
</span><span>The compound AlCl3 is an ionic compound (metal and nonmetal), and therefore does not require prefixes. so AlCl3 is aluminum chloride.
</span><span>
Both of nitrogen and chlorine is nonmetal, but aluminum is metal. Metal with nonmetal will make an ionic compound that doesn't need prefixes.</span>
4 elements are classified in group 4 like titanium, zirconium, hafnium and ruthorfordium
