To determine the direction of polarity of each bond, we must know the electronegativities of each atom involved in the bonds.

Si = 1.90
P = 2.19
S = 2.58

As we move right across a row in the periodic table, the atoms become more electronegative. The direction of polarity in a bond will have the partial positive charge on the less electronegative atom and the partial negative charge on the more electronegative atom. Therefore, the direction of polarity of each bond is as follows:

(δ⁺)Si - P(δ⁻)
(δ⁺)Si - S(δ⁻)
(δ⁻)S - P(δ⁺)

Since silicon is the least electronegative, it will have the partial positive charge in each bond. And since sulfur is the most electronegative, it will have a partial negative charge when bonded to either silicon or phosphorus.

How many moles are in 124.7 g of Ba(OH)2
Alekssandra [29.7K]

Answer:

0.73 mol

Explanation:

No. of moles(n)= Given mass/molar mass.

Given mass=124.7g

Molar mass of Ba(OH)2= Molar mass of (Barium+2Oxygen+2Hydrogen)=137+32+2=171g

No. of moles= 124.7g/171g=0.73 mol

You have collected a tissue specimen that you would like to preserve by freeze drying. To ensure the integrity of the specimen,
Reika [66]

Answer:

The maximum pressure is 612.2 Pa

Explanation:

The pressure of the ice (P1) = 624 Pa

The temperature of the ice = 273.16 K

The maximum temperature the specimen = - 5 oC

                                                                     = -5 + 273 = 268K

The maximum Pressure the freeze drying can be will be (P2) = ?

Using Pressure law, which shows the relationship between pressure and temperature.

                        P1 / T1 = P2 / T2

                       P2 T1 = P1 T2

                       P2 = P1 T2 / T1

                       P2 = 624 × 268 / 273.16

                       P2 = 612.2 Pa

The maximum pressure at which drying can be carried out is 612.2 Pa

Suggest a method for measuring the size of the colony.
Evgen [1.6K]

Answer:

Counting the number of colonies that arise on a pour plate can calculate the concentration by multiplying the count by the volume spread on the pour plate. Direct counting methods are easy to perform and do not require highly specialized equipment, but are often slower than other methods
