For, ClO3- there are 26 valence electrons, so total pairs of electrons are 13.
Answer:
<h3>The answer is 1.59 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 12.5 g
density = 7.87 g/cm³
We have

We have the final answer as
<h3>1.59 cm³</h3>
Hope this helps you
When 2 moles burn 6 moles of O2 is produced !
so for 16 moles , (6/2)×16= 48 moles will be produced !
so answer is A , 48 moles !
The answer is A. 1350
(ALL NUMBERS Except the grams is given from the equation)
18.21mol HNO3/1 * 1mol MgN206/2mol/ 2mol HNO3 * (molar mass-->)148.30 MgN206/ 1mol MgN2O6
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
