Answer:
(b) IE₂ of Ga > IE₂ of Ge
Explanation:
Electronic configuration of Ga is [Ar] 3d¹⁰4s²4p¹
Electronic configuration of Ge is [Ar] 3d¹⁰4s²4p²
After 1st ionisation , Ga becomes [Ar] 3d¹⁰4s² and becomes stable . Its
2 nd ionisation requires higher amount of ionisation energy. In case of Ge , there are 2 electrons in outermost orbital so it becomes stable after ionisation of 2 electrons.
At first sight it doesn't bode well. The key is in how firmly the protons and neutrons are held together. In the event that an atomic response produces cores that are more firmly bound than the firsts then vitality will be created, if not you should place vitality into make the response happen.
Answer:
MgCl2-> Mg+Cl
mass 5.00g Mass=1.263g
RFM Mg=24+35.5 ×2= 95 RFM= 24
moles= 5.00÷ 95= 0.0526 Moles=0.0526
Explanation:
mas of Mg= 1.263 grams
In the given equations for chemical reaction, The Equation No. 2 represents an endothermic chemical reaction.
<h3>What is an Endothermic Chemical Reaction ?</h3>
A reaction which uses energy for the formation of products is known as endothermic reaction.
In the Given Equations,
Equation no. 2 shows the uses of energy with reactants at right hand side which accounts the involvement of energy for the formation of product.
Hence, Equation 2 is a Endothermic chemical reaction.
