Which compound is a polar molecule and has a linear geometry

Chemistry
1 answer:
kirill115 [55]3 years ago
6 0

Answer:

Linear molecule is a molecule in which atoms are deployed in a straight line (under 180° angle). Molecules with an linear electron pair geometries have sp hybridization at the central atom. An example of linear electron pair and molecular geometry are carbon dioxide (O=C=O) and beryllium hydride BeH2.

What mass of iron would be required to react with 10.0L of O2 gas?
SashulF [63]

33.2 g of iron (Fe)

Explanation:

We have the following chemical reaction in which iron react with oxygen to form the iron (III) oxide:

4 Fe + 3 O₂ → 2 Fe₂O₃

number of moles = volume / 22.4 (L/mole)

number of moles of O₂ = 10 / 22.4

number of moles of O₂ = 0.446 moles

Taking in account the chemical reaction we devise the following reasoning:

if           4 moles of Fe react with 3 moles of O₂

then     X moles of Fe react with 0.446 moles of O₂

X = (4 × 0.446) / 3 = 0.595 moles of Fe

number of moles = mass / molar weight

mass =  number of moles × molar weight

mass of Fe = 0.595 × 55.8

mass of Fe = 33.2 g

Why do we use conversion factors instead of just multiplying or dividing as needed? What’s the advantage?
Scrat [10]
If you’re referring to stoichiometry, which usually involves the long t-tables of multiple conversions, then you’re not alone in wondering the purpose of using them. The purpose of conversion tables is to help keep track of what you’re doing. When quickly converting one value to another, it’s very easy to forget a particular piece to the puzzle, or to use a factor that doesn’t work for that instance. Teachers usually draw out a t-table every time they work a problem so as not to confuse students, but anytime you’re working with funky units or converting across systems (metric to imperial and vice versa) it’s a good idea to use them.

Determine the electron-group arrangement, molecular shape, and ideal bond angle(s) for each of the following:
antoniya [11.8K]

The electron group arrangement of PH₃ is tetrahedral. The molecular shape is a Trigonal pyramid, and the bond angle is 93°.

<h3>What is the bond angle?</h3>

The angle between the atoms in a compound is known as the bond angle. The degree of the binding angle is specified. There is also the bond length. It is the separation between the two atoms' nuclei.

The bond angle between the atoms of phosphine is 93°. It has one lone pair. The central atom is covered with 4 atoms.

Thus, the electron-group arrangement of phosphine is tetrahedral. The molecular geometry or shape is a trigonal pyramid. The bond angle is 93°.
