18.53 For CaO, the ionic radii for Ca2 and O2 ions are 0.100 and 0.140 nm, respectively. If an externally applied electric field

gogolik [260]

Answer:

$= 1.92*10^-^3^0 C.m$

Explanation:

Given:

$r_ca_^2_^+ = 0.100 nm$

$r_o_^2_^- = 0.14 nm$

Let's find the distance of separation between cation and anion when there is no applied electric field with the formula:

$d = r_ca_^2_^+ + r_o_^2_^-$

d = 0.100 nm + 0.140 nm

= 0.240 nm

Let's also calculate the distance of separation between anion and cation when there is an applied electric field.

We use the formula:

∆d = 5%d => 0.05d

= 0.05 * 0.024 nm

∆d = 0.0120 nm

$0.120* 10^-^9m$

$= 1.20*10^-^1^1m$

Given magnitude of each dipole= $1.602*10^-^1^9 C$

Let's find the dipole moment, with the formula:

p = q∆d

Substituting figures in the formula, we have:

$p = 1.602*10^-^1^9 * 12*10^-^2^1$

$= 1.92*10^-^3^0 C.m$

How many hydrogen atoms are represented by (CH3)2CHOH?

lozanna [386]

Answer:

8 Hydrogen Atoms

Explanation:

The subscripts that are next to the coefficient (letter) indicates how much atoms the element/compound has.

So:

(CH3) × 2 ⇒ 6 hydrogen atoms

+ 1 from (CH) and another from (OH) ⇒ 8 atoms
