Is the molecule NO nonpolar covalent, polar covalent, or ionic?

Chemistry

Answer: Option (B) is the correct answer.

Explanation:

A covalent compound is defined as the compound in which there will be sharing of electrons between the combining atoms.

An ionic compound is defined as the compound in which there will be transfer of electrons from one atom to another.

A non-polar covalent compound is defined as the compound in which there will be equal sharing of electrons between the combining atoms.

A polar covalent bond is defined as the bond in which there will be unequal sharing of electrons between the combining atoms.

For example, in a NO molecule the oxygen atom is more electronegative than nitrogen atom. Hence, partial charges will tend to develop on both nitrogen and oxygen.

Also, there will be unequal sharing of electrons.

Thus, we can conclude that NO molecule is a polar covalent compound.

B. Polar Covalent, NO is not a symmetrical molecule, therefore making it Polar rather than Non-Polar.

Which element is oxidized in the reaction below? fe(co)5 (l) + 2hi (g) fe(co)4i2 (s) + co (g) + h2 (g)?
DanielleElmas [232]
Oxidation state of I is (-1) and for CO it is zero. Let's assume that the oxidation state of Fe in Fe(CO)₄I₂<span> (s) is x. For whole compound, the charge is zero.

Sum of oxidation numbers in all elements = Charge of the compound.

Here we have 1Fe , 4CO and 2I
hence we can find the oxidation state as;
 x + 4*0 + 2*(-1) = 0
 x + 0 - 2            = 0
                   x     = +2
Hence the oxidation state of Fe in product </span>Fe(CO)₄I₂ (s) is +2.

Same as we can find the oxidation state (y) of Fe in Fe(CO)₅(s).
y + 5*0 = 0
   y        = 0

Since oxidation state of Fe increased from 0 to +2, the oxidized element is Fe in the given reaction.

What was the major weakness of Wegener's theory of continental drift
Alik [6]

Alfred Wegener proposed the continental drift theory  in four reasons. One, he hypothesized that the continents were once a giant continent. Two, he observed that there are fossils found of the same kind in the different locations. Three, he found that the edge of opposing continents somehow fits if they are combined, almost like a puzzle. And four, there are glacial scars that are left behind by a larger glacial continent. His greatest weakness of Alfred Wegeners’ continental drift theory was he could not explain what kind of force that caused this continents to move far from each other.

Calculate the volume in ml of 0.200 M na2co3 needed to produce 2.00 g of caco3 there is an excess of cacl2
UkoKoshka [18]

Answer:

V=100mL

Explanation:

Hello.

In this case, since the chemical reaction is:

Na_2CO_3+CaCl_2\rightarrow  CaCO_3+2NaCl

We next compute the moles of sodium carbonate from the 2.00 grams of calcium carbonate via their 1:1 mole ratio in the chemical reaction:

n_{Na_2CO_3}=2.00gCaCO_3*\frac{1molCaCO_3}{100.09gCaCO_3}*\frac{1molNa_2CO_3}{1molCaCO_3}  \\\\n_{Na_2CO_3}=0.0200molNa_2CO_3

Thus, by knowing the molarity, we compute the volume:

M=\frac{n}{V}\\ \\V=\frac{n}{M}=\frac{0.0200mol}{0.200mol/L}\\  \\V=0.100L*\frac{1000mL}{1L}\\ \\V=100mL

Best regards.
