Carbon only makes four bonds since that is all it needs to fill its valence shell creating an octet. It can't have more than an octet since it is in the second row which means it doesn't have d orbitals to dump extra electrons into..
The combinations that can happen are as fallows:
4 single bonds
2 single bonds and 1 double bond
2 double bonds
1 triple bond and 1 single bond

In the list of possible answers the only one that fits one of those four options is one triple bond and one single bond.

I hope this helps. Let me know if anything is unclear or if you want me to explain anything further.

g 304 mL of a 0.36 M potassium hydroxide solution is added to 341 mL of a 0.51 M lithium hydroxide solution. Calculate the pOH o

Liono4ka [1.6K]

Answer:

pOH = 0.36

Explanation:

Both potassium hydroxide and lithium hydroxide solutions are strong bases, so you assume 100% dissociation.

1. Potassium hydroxide solution, KOH

Volume, V = 304 mL = 0.304 liter

Molarity, M = 0.36 M

number of moles, n = M × V = 0.36M × 0.304 liter = 0.10944 mol

1 mole of KOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.10944

2. LIthium hydroxide, LiOH

Volume, V = 341 mL = 0.341 liter

Molarity, M = 0.51 M

number of moles, n = M × V = 0.341 liter × 0.51 M = 0.17391 mol

1mole of LiOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.17391

3. Resulting solution

Number of moles of OH⁻ ions = 0.10944 mol + 0.17391 mol = 0.28335 mol

Volume of solution = 0.304 liter + 0.341 liter = 0.645 liter

Molar concentration = 0.28335 mol / 0.645 liter = 0.4393 M

4. pOH

$pOH=-\log [OH^-]=-\log (0.439)=0.36$ ← answer

If the pressure of a gas is 100 kPa when the volume is measured to be 500 mL. What pressure would need to be exerted to have the

Korvikt [17]

Answer:

p2=125 kpa

Explanation:

Using Boyle's law

p1 x v1 = p2 x v2

p1=100kpa

v1=500ml

p2=?

v2=400ml

p2= (100x500)\400

p2=125 kpa

Answer:

Pressure inside soda can = 5.56 atm

Explanation:

Given data:

Initial volume = 1250 mL

Initial pressure = 1.00 atm

Final volume = 225 mL

Final pressure = ?

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.00 atm × 1250m L = P₂ × 225 mL

P₂ = 1250 atm. mL/ 225 mL

P₂ = 5.56 atm

The weak ionization constant (Ka)

Nostrana [21]

Carbonic acid is a weak acid. Its weak ionization constant (Ka) is equal to:

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]

A weak acid is an acid that dissociates partially in the water.

The equation for the acid dissociation of carbonic acid is:

H₂CO₃ ⇄ H⁺ + HCO₃⁻

The weak ionization constant (Ka) is the equilibrium constant for this reaction, that is, the product of the concentration of the products divided by the product of the concentrations of the reactants, all of them raised to their stoichiometric coefficients.

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]

Carbonic acid is a weak acid. Its weak ionization constant (Ka) is equal to:

Ka = [H⁺] [HCO₃⁻] / [H₂CO₃]
