Question
Formation of Sodium Chloride is an example of
Solution
The bond formed by a complete transfer of one or more electrons is called electrovalent or ionic bond. The compound so formed is called the electrovalent compound. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms . A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom.
17.6% of 250 + √? = 70% of 90
[∛(91125/19683 )- ∛(3375/5832 ) ] × ∛(512/9261) = ? - √(484/3969)
25% of 1600 – 152 = ? × 5
18 + 28 ÷ 4 - 14 = ? - 35
...Determine the value (6.375)2Â - (3.125)2Â
What value should come in the place of (?) in the following questions?
30% of 160 – 25% of 240 + 43 = ?
382 + 482 + 572 = ? - (81 x 49)
Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
42 * 7 * 64 * 11 * 6 *4
15% of 1800 + 22 = ?Â
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?Â
