The correct answer is option A, that is, cooler and more rigid outer portion.

The lithosphere of the Earth comprises the crust and the uppermost mantle that forms the rigid and hard outer layer of the Earth. The lithosphere is sub-differentiated into tectonic plates. The topmost section of the lithosphere, which chemically reacts with the hydrosphere, atmosphere, and biosphere via the soil producing procedure is known as the pedosphere. The lithosphere is situated above the asthenosphere that is the hotter, weaker, and deeper component of the upper mantle.

s fo"rmed when one atom of carbon (atomic number 6) is covalently" bonded with two atoms of oxygen (atomic number 8). What is th

sweet [91]

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.

<u>Explanation:</u>

A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.

Carbon is the 6th element of the periodic table having electronic configuration of $1s^22s^22p^2$

This element requires 4 electrons to complete its shell.

Oxygen is the 8th element of the periodic table having electronic configuration of $1s^22s^22p^4$

This element requires 2 electrons to complete its shell.

So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.

Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.

Answer:

Yes, the formed product is calcium nitride, $Ca_3N_2$ .

Explanation:

Hello,

In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

$N_2+Ca\rightarrow Ca_3N_2$

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.

Best regards.

Answer:

144 g

Explanation:

Use the mole ratio of 4 mol CO2 for every 9 mol O2 to convert from mol O2 to mol CO2. Then use the molar mass of CO2 to convert from mol of CO2 to grams of CO2.

7.34 mol O2 • (4 mol CO2 / 9 mol O2) • (44.01 g CO2 / 1 mol CO2) = 144 g CO2
