Answer:
a. the maximum number of σ bonds that the atom can form is 4
b. the maximum number of p-p bonds that the atom can form is 2
Explanation:
Hybridization is the mixing of at least two nonequivalent orbitals, in this case, we have the mixing of one <em>s, 3 p </em> and <em> 2 d </em> orbitals. In hybridization the number of hybrid orbitals generated is equal to the number of pure atomic orbital, so we have 6 hybrid orbital.
The shape of this hybrid orbital is octahedral (look the attached image) , it has 4 orbital located in the plane and 2 orbital perpendicular to it.
This shape allows the formation of maximum 4 σ bond, because σ bonds are formed by orbitals overlapping end to end.
And maximum 2 p-p bonds, because p-p bonds are formed by sideways overlapping orbitals. The atom can form one with each one of the orbitals located perpendicular to the plane.
Answer:
I believe it's false because the atomic number is the number of protons in the nucleus of an atom.

11.Liquid water changes to water vapor when it evaporates or boils. The gas inside the bubbles of boiling water is water vapor. Water vapor can change back into liquid water when it cools down. ... The “steam” you see is really tiny drops of liquid water that form when the water vapor cools.
12.Plastic pollution has become one of the most pressing environmental issues, as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or nonexistent. But the developed world, especially in countries with low recycling rates, also has trouble properly collecting discarded plastics. Plastic trash has become so ubiquitous it has prompted efforts to write a global treaty negotiated by the United Nations
Answer:
Pressure = 0.64 atm
Explanation:
Use Ideal Gas Law PV = nRT => P = nRT/V
n = moles CO₂(g) = 66g/44g/mol = 1.5 mol CO₂
R = Gas Constant = 0.08206 L·atm/mol·K
T = Temperature = -14.5°C = (-14.5 + 273)K = 258.5 K
V = 50.0 Liters
P = (1.5 mol)(0.08206 L·atm/mol·K)(258.5 K)/(50.0 L) = 0.64 atm
