Answer:
See explanation below
Explanation:
In this case, let's see both molecules per separate:
In the case of SeO₂ the central atom would be the Se. The Se has oxidation states of 2+, and 4+. In this molecule it's working with the 4+, while oxygen is working with the 2- state. Now, how do we know that Se is working with that state?, simply, let's do an equation for it. We know that this molecule has a formal charge of 0, so:
Se = x
O = -2
x + (-2)*2 = 0
x - 4 = 0
x = +4.
Therefore, Selenium is working with +4 state, the only way to bond this molecule is with a covalent bond, and in the case of the oxygen will be with double bond. See picture below.
In the case of CO₂ happens something similar. Carbon is working with +4 state, so in order to stabilize the charges, it has to be bonded with double bonds with both oxygens. The picture below shows.
Answer : The grams of consumed is, 89.6 grams.
Solution : Given,
Mass of = 265 g
Molar mass of = 80 g/mole
Molar mass of = 28 g/mole
First we have to calculate the moles of .
The given balanced reaction is,
from the reaction, we conclude that
As, 1 mole of produces from 1 mole of
So, 3.2 moles of produces from 3.2 moles of
Now we have to calculate the mass of
Therefore, the grams of consumed is, 89.6 grams.
I'm going to suppose you want the adjusted chemical reaction, using the formulas of the compounds. You can see it in the image attached.
