When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form co2 (carbon dioxide), which is

xxTIMURxx [149]

<h3>Answer:</h3>

1.5 × 10⁸ Kg of CO₂ / Year

<h3>Solution:</h3>

According to statement,

1 kwh generation produces = 0.73 Kg of CO₂

So,

700 kwh generation will produce = X Kg of CO₂

Solving for X,

X = (700 kwh × 0.73 Kg) ÷ 1 kwh

X = 511 Kg of CO₂ / Year

Also, as calculated,

1 household produces = 511 Kg of CO₂ / Year

Then,

300,000 households will produce = X Kg of CO₂ per Year

Solving for X,

X = (300000 households × 511 Kg) ÷ 1 household

X = 153300000 Kg of CO₂ / Year

Or,

X = 1.5 × 10⁸ Kg of CO₂ / Year

or the solution containing Zn2+(aq), n is 2, so the MM/n ratio will be the molar mass of Zn divided by 2: MM/n = (65.39 g/mol) /

yKpoI14uk [10]

Answer:

MM/n will be less than the theoretical value

Explanation:

Provided that

The plating efficiency is proportional to the element weight

i.e.

$\frac{Zn^2}{(aq)}$

That represents $\frac{MM}{n\ value}$

So,

MM by N value is

= 65.39 g /mol ÷ 2

= 32.70 g/mol

Also, the experimental plating value is 0.55 that represents that it is much lesser than the normal value

So it would be concluded that the MM by N would be lower than the theoretical value

What is the lewis structure and formal charge of CH2O

aksik [14]

Diagram A shows the Lewis structure (LS) of CH_2O. The formal charge on each atom is zero.

To get the formal charge (FC) on the atoms, cut each bond in half, as in <em>Diagram B</em>. Each atom gets the electrons on its side of the cut.

Formal charge = valence electrons in isolated atom - electrons on bonded atom

FC = VE - BE

<em>On O: </em>

VE = 6

BE = 2 lone pairs 2 + 2 bonding electrons = 4 + 2 = 6

FC = 6 – 6 = 0.

<em>On H: </em>

VE = 1

BE = 1 bonding electron

FC = 1 – 1 = 0

<em>On C: </em>

VE = 4

BE = 1 in each single bond + 2 in the double bond = 2 + 2 = 4

FC = 4 - 4 = 0
