What is the net ionic equation? (This is already balanced, just need the net ionic) 2CH3COOH(aq)+ Sr(OH)2(aq)----> Sr(CH3COO)2(aq)+2H2O(l)

Answers

Answer 1

Answer: Net ionic equation should be like this :
CH3COOH(aq) + OH- --> CH3COO- + H2O(l)
According to the fact that acetic acid is too weal and non-ionized, put CH3COOH, Sr(OH)2 is not so strong but can dissolve therefore can ionize.

If the atomic radius of a calcium crystal is 180 pm, what is the length of the edge of the unit cell? (the calcium crystal forms

Answers

The edge length of a a unit cell of calcium crystal is 509.12 pm.

Structure of the Calcium crystals

Calcium crystal has a face center cubic (FCC) structure.

Edge length of the unit cell

The edge length of the unit cell for face center cubic (FCC) structure is given in the following formula;

a = 2r√2

where;

a is edge length
r is the radius

a = 2 x 180 x √2

a = 509.12 pm

Thus, the edge length of a a unit cell of calcium crystal is 509.12 pm.

Calcium crystal has a face center cubic (FCC) structure. For FCC structure,
relation between edge length (a) and radius (r) is
a = 2√2 r
Given: r = 180 pm
Therefore, a = 2√2 180
= 2 x 1.141 x 180
= 410.76 pm

The length of the edge of the Ca unit cell is 410.76 pm.
