Once a metal is above another in series it is more reactive than it and will be able to displace it from its compound. Ex: Iron will displace lead from its compound but Iron cannot displace zinc from its compound.
Hope this helps!
Answer:
1.10 g/mL
Explanation:
The amount of volume an object displaces is the amount of volume that object takes up.
7.87 - 1.67 = 6.2
The object has a volume of 6.2 mL.
You have the mass (6.82 g) and the volume (6.2 mL). Divide the two value to find the density.
(6.82 g)/(6.2 mL) = 1.10 g/mL
The density of the object is 1.10 g/mL.
Answer:
The answer is Sodium chloride.
Na is sodium and Cl is chlorine.
Answer:
156.86 g / mol
Explanation:
We start from the molarity law
Cm = n / V
n = w / M
then
Cm = (w / M) / V
Cm = w / (M × V)
where:
Cm is the molarity
n number of moles
w a mass of the solute
M is the molar mass of the solute (which is needed)
V the volume of the solution in liters
Then the M can be calculated as following:
M = w / (Cm × V)
M = 100 / (0.75 × 0.85) = 156.86 g / mol
Insulating materials are composed of atoms with <u>tightly bound outer electrons.</u>
<h3>What is Insulating Material ? </h3>
The material that stop the flow of Sound, Heat and Electricity by them are called Insulating Material. Insulator are the materials whose atoms have tightly bound outer electrons because electrons are not free to shared by neighboring atoms.
Examples: Glass, Plastic, Rubber, Air and Wood.
<h3>What are the types of Insulating Material ?</h3>
There are mainly three types of Insulating Material:
- Heat Insulator
- Electricity Insulator
- Sound Insulator
Thus from the above conclusion we can say that Insulating materials are composed of atoms with <u>tightly bound outer electrons.</u>
