<span>Metals are good conductors of electricity because of the free electrons that is present in their outer shell that makes them good conductors of electricity. This is the most accepted fact that for any thing to transmit electricity by being a good conductor they need more free electrons in their outer shell</span>

metal   have   free electrons  in  their   outer  shell  which  make  them  generally  good  conductors  of  electricity. Example  is  the  copper  which   is  used  for  electrical  wiring   since  is  a good  conductor  of  electricity.  copper  with   electronic configuration  of  (Ar)4s2 has  two  free  electrons  in  their  outer  most shell which  allow  it  to  conduct  electricity.

Explain why the population of trout might increase if the population of frogs decreased
castortr0y [4]
If the population of frogs decreased, an animal that eats frogs and trout will decrease because it's food source is declining. Then, since the predator population is declining, the trout population will increase. The trout will have less predators to worry about.

Molten gallium reacts with arsenic to form the semiconductor, gallium arsenide, GaAs, used in light-emitting diodes and solar ce
Vsevolod [243]

Answer:

a) 1.2g of arsenic b) 0.64g of arsenic c) 3.481g of gallium d) 3.806g of gallium e) 2.61g arsenic

Explanation:

The balanced equation is:

Ga + As = GaAs, 1:1 mole ratio

a) mass (gallium)/ molar mass of Ga = 4/ 69.723 = 0.0574mol

Mass (arsenic)/ molar mass of As = 5.5/74.9216 = 0.0734, subtracting the moles from each other (knowing already that the ratio is 1:1), arsenic is in excess by 1.2g

b) repeating the procedure (changing the values)

It will be 0.0574 to 0.06593

Arsenic is in excess by 0.00854

0.00854* mass of arsenic (such must be done for the first remaining mole) = 0.64g

c) the mole ratio is 0.0574: 0.00747

Gallium is in excess by 0.05

Mass of excess gallium = 0.05* 69.723 = 3.481g

d) using the mass given, the new ratio is

0.128: 0.0734

Gallium is in excess by 0.054mol

Mass of excess gallium = 0.054*69.723 = 3.806g

e) using the mass again, the new ratio is 0.0574: 0.02,

Gallium is in excess by 0.0374*69.723 = 2.61g

The kinetic molecular theory (KMT) deals specifically with
fgiga [73]
This kind of questions cannot be open because there might be many different answers depending of the focus.

In fact, I found the set of options that comes with this questions. This is:

A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.

Of course, the answer is the option D. molecular motion.

And, of course, you need an explanation.

It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.

With that you likely had been able to answer the question. But it is good to know what the molecular theory is.

The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.

Question<br> What is the molarity of a 400 mL solution containing 0.60 moles of NaCl?
Mumz [18]

Answer:

0.24 M

Explanation:

Molarity = Moles solute / Liters solution

Step 1: Identify variables

400 mL = Liters solution

0.60 moles = Moles solute

Step 2: Identify conversions

1 L = 1000 mL

Step 3: Convert mL to L

400mL(1 L/1000mL) = 0.4 L

Step 4: Find molarity

M = (0.4 L)(0.60 mol) = 0.24 M
