<h2>Let us complete it :</h2>

Explanation:

let us study about formation of sodium phosphide

Electrons are transferred from atoms of sodium to atoms of phosphorous

The sodium atom looses electrons and the phosphorus atoms

gains electrons .

C. This transfer makes the sodium atoms acquire positive charge and phosphorous acquire negative charge .

As a result, the sodium and phosphorus atoms strongly bond with

each other.

A sealed 1.0L flask is filled with 0.500 mols of I_2 and 0.500 mols of Br_2. When the container achieves equilibrium the equilib

Answer:

[IBr] = 0.049 M.

Explanation:

Hello there!

In this case, according to the balanced chemical reaction:

$I_2+Br_2\rightarrow 2IBr$

It is possible to set up the following equilibrium expression:

$K=\frac{[IBr]^2}{[I_2][Br_2]} =0.0110$

Whereas the the initial concentrations of both iodine and bromine are 0.50 M; and in terms of $x$ (reaction extent) would be:

$0.0110=\frac{(2x)^2}{(0.50-x)^2}$

Which can be solved for $x$ to obtain two possible results:

$x_1=-0.0277M\\\\x_2=0.0245M$

Whereas the correct result is 0.0245 M since negative results does not make any sense. Thus, the concentration of the product turns out:

$[IBr]=2x=2*0.0249M=0.049M$

Regards!

Explain how to calculate the density of a regular shaped object such as a rectangular box.

belka [17]

The density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.

<h3>Derived quantities</h3>

These are physical quantities which are obtained from fundamental quantities. I'm order words, derived quantities are quantities which are obtained from the combination of of fundamental quantities either by addition, division or multiplication

Some few examples of derived quantities are as follows:

Density

Velocity
Upthrust
Volume
Acceleration

So therefore, the density of a regular shaped object such as a rectangular box is calculated as thus:

The amount of matter is its mass, and the space it takes up is its volume.

So therefore, to calculate the density of an object such as the a regular shaped one like a rectangular box;

Its density = mass / volume.
