Carbon can bond to itself to form which of the following?

1 answer:

4 0

Carbon has 4 valence electrons that can be involved in the formation of a covalent bond. This is why it can form various types of bonds with itself or other elements. Depending on the number of valence electrons involved in the binding, the bond can be a single, double or triple bond.

Explanation:

Remember the atoms sharing electrons in a covalent bond are aimed at achieving stable electron configuration. Carbon (2.4) being in the middle of the 2nd period seeks to be either 2 or 2.8.

This is why carbon based structures can vary so much due to the large variability in which the carbon atoms can bond. Remember carbon is the same element that forms graphite, diamond, and coal.

The vaporization of 1 mole of liquid water (system) at 100.9 C, 1.00 atm, is endothermic.

yan [13]

Answer:

a) The work done is 10.0777 kJ

b) The water's change in internal energy is -122.1973 kJ

Explanation:

Given data:

1 mol of liquid water

T₁ = temperature = 100.9°C

P = pressure = 1 atm

Endothermic reaction

T₂ = temperature = 100°C

1 mol of water vapor

VL = volume of liquid water = 18.8 mL = 0.0188 L

VG = volume of water vapor = 30.62 L

3.25 moles of liquid water vaporizes

Q = heat added to the system = -40.7 kJ

Questions: a) Calculate the work done on or by the system, W = ?

b) Calculate the water's change in internal energy, ΔU = ?

Heat for 3.25 moles:

$Q_{1} =3.25*(-40.7)=-132.275kJ$

The work done:

$W=-nP*delta(V)=-3.25*101.33*(0.0188-30.62)=10077.6637J=10.0777kJ$

The change in internal energy:

$delt(U)=W+Q_{1} =10.0777-132.275=-122.1973kJ$

The electron cloud model describes which of the following?

HACTEHA [7]

1) The trails left by an electron as it moves around the nucleus
The electron model dictates that the electrons have no fixed position so it traces their path.
2) 8
Atomic number is equivalent to proton number
3) Its mass is lowered, but it is still the same element.
The element's identity is due to the number of protons; however, neutrons play a large role in an atom's mass. Thus, the mass will decrease but the element will be the same. Such variants are called isotopes.

How do you solve this ?NH4+NO4->N2+O2+H2O2

I'm assuming you wanted this equation balanced? If you typed it correctly, it's already balanced for you. :)
