Answer : 7.87 X
.
Explanation : To find the fraction of schottky defects in the given lattice of CsCl,
we use the formula,
on solving with the given values ,
and T as 645 + 273 K and rest are the constants.
we get the answer as 7.87 X
.
Answer:
NH2.
Explanation:
The mass of hydrogen in the sample = 1.525 - 1.333 = 0.192g.
Dividing the 2 masses by the relative atomic mass of hydrogen and nitrogen:
H: 0.192 / 1.008 = 0.1905
N: 1.333 / 14.007 = 0.09517
The ratio of N to H = 0.09517 : 0.1905
= 1 : 2.
So the empirical formula is NH2.
Answer:
group of people assembled for religious worship.
a second definition:
a gathering or collection of people, animals, or things.
other words that mean the same thing as cogeneration:
assembly gathering assemblage convocation crowd flock group mass multitude!

The element that has the smallest atomic radius is <u>titanium</u>
<em><u>explanation</u></em>
- Calcium,potassium, scandium and titanium are in period 4 in the periodic table.
- Generally the atomic radius decreases across the period (from the left to the right) . This is because across the period there is increase in nuclear charge which make electrons been strongly attracted to the nuclear.
- Titanium is in atomic number 22 thus it has more nuclear charge that calcium,potassium and scandium therefore titanium has the smallest atomic radius.
B- Carbon nitrogen and oxygen. All organisms are made up of carbon, oxygen is essential to breath, and nitrogen makes up most of earth's atmosphere.
