Answer:For Fe

Z=26

Explanation:

1s2 2s2 2p6 3s2 3p6 4s2 3d6

Are there 26 electrons here? Why should there be 26?

So going back to the inert gas, argon ( Z=18 ), we get

[Ar] 4s2 3d6

Make sure to check your work by counting the electrons you have

Taking into account the definition of density, the density of the sample is 0.5 $\frac{g}{mL}$ .

It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density allows you to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

In this case, you know:

mass= 6 g
volume= 12 mL

Then, replacing in the definition of density:

$density=\frac{6 g}{12 mL}$

Solving:

density= 0.5 $\frac{g}{mL}$

Finally, the density of the sample is 0.5 $\frac{g}{mL}$ .

which term is used when sugar is completely dissolved in water

GaryK [48]

The term which is used is homogeneous.
when sugar is completely dissolved in the water, the mixture or solution homogeneous, both in same phase and same uniform texture that is liquid.
There two types of mixtures are heterogeneous and homogeneous in different phases.
If sugar is not completely dissolved in water and you see the crystals of sugar in water, then the solution will be heterogeneous.
