- Describe the industrial production of dihydrogen from steam. Also write the chemical reaction involved. Answer: Dihydrogen is made industrially by passing steam over hydrocarbons or red-hot coke at high temperature, followed by the water-gas sh... 1
- Describe the diagonal relationship between Li and Mg with the help of two illustrative properties. Answer: Lithium (group 1, period 2) resembles magnesium (group 2, period 3), its diagonal neighbour, because Li⁺ and Mg²⁺ have similar sizes... 1
- Beryllium oxide is treated separately with aqueous HCl and aqueous NaOH solutions. Answer: BeO is amphoteric, so it dissolves in both HCl and NaOH. With aqueous HCl it acts as a base and forms beryllium chloride and water:... 1
- Magnesium is heated in air. Answer: Magnesium burns with a dazzling white light to form magnesium oxide, along with some magnesium nitride. Air is mainly oxygen and nit... 1
- A 50% solution of sulphuric acid is subjected to electrolyte oxidation and the product is hydrolysed See below image 2
- Lithium floats an water while sodium floats and catches fire when put in water. When lithium and sodium react with water, hydrogen gas is released. Due to these hydrogen gas bubbles, lithium and sodium floats on water. e... 2
- Alkaline earth metals have low values of electronegativity; which decrease down the group Electronegativity represents attractive force exerted by the nucleus on shared electrons.The general outer electronic configuration of alkal... 2
- Collect the information of preparation of dihydrogen and make a chart Chart: methods of preparing dihydrogen ( H₂ ) MethodReaction Laboratory: zinc granules with dilute acid Zn + 2HCl → ZnCl₂ + H₂ Laboratory: z... 1
- How the atomic size vary in a group and across a period? Explain with suitable example. Answer: Atomic size increases down a group and decreases from left to right across a period. Down a group: each new element has one more she... 1
- Define ionization enthalpy. Name the factors on which ionisation enthalpy depends? How does it vary down the group and across a period? Variation of ionization energy down the group: On moving down the group, the ionization enthalpy decreases. This is because the electron is... 2
