What word or two-word phrase best describes the shape of the fluoroform molecule?

Vlad [161]

Answer : The shape of the fluoroform molecule is Tetrahedral.

Explanation :

First we have to calculate the Hybridization of the molecule by formula,

$\text{Number of electrons} = \frac{1}{2}[V+H-C+A]$

where,

V = Number of valence shell electron in central atom

H = Number of neighboring monovalent atom

C = charge of cation

A = charge of anion

The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.

The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.

There is no charge of cation and anion on the given molecule.

V = 4

H = 1 Hydrogen atom + 3 fluorine atom = 4

C = 0

A = 0

By the above hybridization formula, we get

$\text{Number of electrons}= \frac{1}{2}[4+4-0+0]$ = 4

The number of electron pair = 4

The number of lone pair = 0

The number of electrons is 4, this means that the hybridization is $sp^{3}$ and the geometry of the molecule is Tetrahedral.

The geometry of the molecule is shown below.

A 20.0 L container at 303 K holds a mixture of two gases with a total pressure of 5.00 atm. If there are 1.70 mol of Gas A in th

meriva

Answer:

moles B = 2.32 moles

Explanation:

In this case, we can assume that both gases are ideals, so we can use the expression for an ideal gas which is:

PV = nRT

From here, we can calculate the total moles (n) that are in the container, and then, by difference, we can calculate how much we have of gas B.

For this case, we will use R = 0.082 L atm / mol K. Solving for n:

n = PV/RT

n = 5 * 20 / 0.082 * 303

n = 4.02 moles

If we have 4.02 moles between the two gases, and we have 1.70 from gas A, then from gas B we simply have:

Total moles = moles A + moles B

moles B = Total moles - moles A

moles B = 4.02 - 1.70

moles B = 2.32 moles

We have 2.32 moles of gas B

What are the chemical properties of beryllium phosphide??

o-na [289]

Answer:

Forms ionic bonds, insoluble, doesn't participate in single or double displacement reactions, non-reactive, high heat of combustion

Explanation:

Beryllium is a metal, since it belongs to group 2A, the alkaline earth metals. It has a total of 2 valence electrons.

Phosphorus, on the other hand, belongs to group 5A and has a total of 5 valence electrons.

We have a compound which has a metal in it, therefore, it's an ionic compound. Beryllium, our metal, loses its 2 electrons to gain an octet and phosphorus, our nonmetal, should gain 3 electrons to have an octet. The oxidation states are +2 and -3 respectively. This means we need 3 beryllium cations and 2 phosphide anions in our formula $Be_3P_2$ .

Beryllium phosphide would be expected to be insoluble, as only beryllium chloride, fluoride, nitrate, phosphate and sulfate are soluble substances, while the remaining ones are expected to be insoluble.

Due to its insolubility, beryllium phosphide would not participate in any ionic reactions, such as single displacement or double displacement.

Since it's insoluble, we expect this compound to be chemically stable and not reactive. This implies that if we wanted to burn it, the heat of combustion would be very high, as a lot of energy would be needed to be supplied in an endothermic reaction in order to burn it.
