The carbon-oxygen double bond is polar.

However, carbon dioxide is a linear molecule. The two dipoles cancel out each other.

Thus, carbon dioxide is a non polar molecule with polar bond.

If 9.6 X 1021 molecules of hydrogen are reacted with excess nitrogen, how many liters of ammonia can be produced at STP?

diamong [38]

The volume of NH₃ produced at STP : 0.237 L

<h3>Further explanation</h3>

Reaction

N₂ + 3H₂ → 2NH₃

1 mol = 6.02 x 10²³ particles

9.6 X 10²¹ molecules of Hydrogen, mol :

$\tt \dfrac{9.61\times 10^{21}}{6.02\times 10^{23}}=1.596\times 10^{-2}~moles$

mol H₂ : mol NH₃ = 3 : 2

mol NH₃ :

$\tt \dfrac{2}{3}\times 1.596\times 10^{-2}=0.0106$

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

The volume of NH₃ :

$\tt 0.0106\times 22.4=0.237~L$

Paul [167]

Answer:

See attached figure.

Explanation:

Hello there!

In this case, according to the given substances, we recall the concept of Lewis structure as such showing the bonds and valence electrons each atom has in the molecule. Thus, since chlorine atoms have seven valence electrons, carbon atoms four of them, hydrogen atoms have 1 and oxygen atoms 6, we are able to draw such Lewis dot structures, by obeying the octet as shown on the attached figure.

Best regards!

Which of the following is true about a municipal bond with a put option? (A) An investor will exercise the option to put the bon

vampirchik [111]

Answer:

(A) An investor will exercise the option to put the bond if yields rise significantly

Explanation:

A put option on the bond is a mechanism to allow the buyer of the bond the ability to compel the lender to repay the principal on the bond. The put option offers the buyer of the bond the ability to collect the principal of the bond anytime they choose until maturity for any purpose.

Recall that once the price drops (that is, the yield increases), put options are exercised. If the yield significantly increased, the put choice on a municipal bond is executed.
