<u>Answer:</u> The balanced chemical equation for the reaction of phosphorus trichloride with water is written below.

<u>Explanation:</u>

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the reaction of phosphorus trichloride with water follows:

PCl_3(l)+3H_2O(l)\rightarrow H_3PO_3(aq.)+3HCl(aq.)

By Stoichiometry of the reaction:

1 mole of liquid phosphorus trichloride reacts with 3 moles of water to produce 1 mole of aqueous phosphorus acid and 3 moles of aqueous hydrochloric acid.

Hence, the balanced chemical equation for the reaction of phosphorus trichloride with water is written above.

Hey there!:

I'll balance it:

PCl3 + H2O ---> H3PO3 + HCl

* PCl3 (l )+ 3 H2O (l)--->H3PO3(aq) +3 HCl(aq)

Hope that helps!

What will happen if the concentration of water inside a cell is higher than the concentration of water outside a cell?
Olegator [25]
If the concentration of water inside a cell is higher than the concentration of water outside a cell, osmosis will take place, as water will move from an area of low solute concentration inside the cell to higher solute concentration, outside the cell.

The noble gases are inert due to the fact that A. their valence shell is empty B. their valence shell is full C. their electrons
coldgirl [10]

Answer:

B) Their valence shell is full

Explanation:

In order to be classified as a noble gas, an element must have a complete octet/ a full shell of valence electrons, as shown in answer B.

A and C are just incorrect. Since noble gasses are very unstable, D is a true statement, but is isn't the correct answer as this does not explain why they are inert.

A public School district furnishes pencils to its elementary school. The pencils the secretary orders from the district warehous
const2013 [10]

Answer:

The minimum number of boxes of pencils to be ordered is 630 boxes.

Explanation:

Since a pupil uses averagely 9.3 pencils

and a box contains 12 pencils,

the school enrollment is also 812

school's enrollment x average use of pencil per student

__________________________________________

            number of pencils in a box

812 x 9.3 = 7551.6

7551.6 /12 = 629.3

Having a total number of 630 boxes of pencils to be ordered.
