B. How many moles of phosphorous pentachloride will react with 7.36 g of water?

Chemistry
1 answer:
Flura [38]2 years ago
5 0

Answer:

0.102 mol

Explanation:

Step 1: Write the balanced equation

PCl₅ + 4 H₂O ⇒ 5 HCl + H₃PO₄

Step 2: Calculate the moles corresponding to 7.36 g of H₂O

The molar mass of H₂O is 18.02 g/mol.

7.36 g × 1 mol/18.02 g = 0.408 mol

Step 3: Calculate the moles of PCl₅ required to react with 0.408 moles of H₂O

The molar ratio of PCl₅ to H₂O is 1:4.

0.408 mol H₂O × 1 mol PCl₅/4 mol H₂O = 0.102 mol PCl₅

Which of the following is mixture backi g soda or carbon or honey or orange juice
vfiekz [6]

Answer:

Honey

Explanation:

Backing soda:

Backing soda is a compound that is made up of only one kind of salt called NaHCO3 or sodium  hydrogen carbonate. All the molecules  of NaHCO3  are identical and we know that a mixture is something made up of two or more than two kinds of things, therefore baking soda cannot be referred to as mixture.

Carbon:

Carbon is not a mixture because its just an element that composed diffreent compounds by reacting with different other elements. In its oure form carbon is not a mixture, but if it is combined with some other substance it can form mixture.

Orange juice:

It depends on what kind of orange juice we are talking about. If we are talking about pure orange juice that is made from fresh oranges,then no - it cannot be called as mixture. However, if sugars,flavors and other preservatives are added like those available in market then it can be a mixture.

Honey:

Honey is a mixture of at-least 181 types of components in which most of all are sugars. These components mix through complex process and give the honey its specific sugary taste. You can see some of the constituent components of honey in attached figure.

Hope it help!

Please help balance this equation <br> _B2Br6 + _HNO3= _B(NO3)3+_HBr
Trava [24]

Answer: B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH

Equation

B2Br6+HNO3=B(NO3)3+HBr

B=2                                 B=1

BR=6                             BR=1

H=1                                  H=1

N=1                                  N=3

O=3                                 O=9

ANSWER

B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH

B=2                                 B=2

BR=6                             BR=6

H=6                                  H=6

N=6                                  N=6

O=18                                 O=18

What property of a solution remains the same after it is diluted?
sineoko [7]
The property of a solution which remain the same after it is diluted is THE AMOUNT OF SOLUTE.
Dilution is the process of adding solvent to a solution. This action decreases the concentration of the solute in the solution. When a solution is diluted, the amount of solvent increase, the total volume increases, the concentration decreases, but the amount of solute stays the same.

What will increase the turgor pressure in a plant
Katena32 [7]

Answer:

Cell expansion and an increase in turgor pressure is due to inward diffusion of water into the cell, and turgor pressure increases due to the increasing volume of vacuolar sap. A growing root cell's turgor pressure can be up to 0.6 MPa, which is over three times that of a car tire.

Explanation...read that and you will have a sucess
