Answer:
niobium 1s22s22p63s23p64s23d104p65s24d3
Answer:
1) pentane is of higher Molecular mass than propane hence heavier member
2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight
3) I) in methanol C = sp3
ii) in methanoic acid C= sp2
5)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bond
Explanation:
See attachment for question 4
The Ammonia present in 2.5 mole of Ammonia is 42.5grams.
<h3>What is a mole ?</h3>
A mole is a measuring unit in Chemistry to measure the number of atoms in certain molar mass of a substance.
It is given that 2.5 mole of Ammonia is present
Grams of Ammonia present in 2.5 mole of Ammonia = ?
Molecular weight of Ammonia = 17 grams.
1 mole of Ammonia = 17 grams of Ammonia
2.5 mole of Ammonia = 17 * 2.5
= 42.5 grams
Therefore 42.5 grams of Ammonia is present in 2.5 mole of Ammonia.
