Answer : The correct option is, (e) eg = trigonal planar, mg = trigonal planar
Explanation :
Formula used :
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is,
That means,
Bond pair = 3
Lone pair = 0
The number of electron pair are 3 that means the hybridization will be and the electronic geometry of the molecule will be trigonal planar.
Hence, the electron geometry (eg) and molecular geometry (mg) of is, trigonal planar and trigonal planar respectively.
Answer:- Mass of the titanium alloy is 7.01 g, choice C is correct.
Solution:- The heat of fusion is given as 422.5 joules per gram and it also says that 2960 joules of heat is required to melt the metal completely.
The suggested equation is,
where Q is the heat energy, m is the mass and Hf is the heat of fusion.
Since, we are asked to calculate the mass, the equation could be written as:
Let's plug in the values in it:
m = 7.01 g
So, the mass of the titanium alloy is 7.01 g, choice C is correct.
