Find the molar mass of fe2o3. Then multiply 4.3 x molar mass of fe2o3/1 moles
Answer:
The heat energy stored within them changes
Explanation:
Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.
In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.
To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below

An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material
Silver's chemical symbol is Ag, and it has a 1+ charge. Nitrogen's chemical symbol is N, and it has a 3- charge. For silver and nitrogen to form a compound, their charges must cancel out to zero. Therefore, we would need 3 silver atoms for each nitrogen atom to balance the charges out. The formula for the silver nitride compound would be Ag3N.
I believe the answer is (B) as molten Kevlar when spun into fiber, its polymers have a crystalline arrangement.
Hope that helped!
Answer:
The new pH of the solution 
Explanation:
Given
pH of bottle of Soda is 
As we know that
pH
log [H+]
We will derive the hydrogen ion concentration when pH is 
log [H+]
Taking anti-log on both the sides, we get -
H+ ion is equal to 
When the hydronuim ion concentration reduces by
of the original concentration, the new hydrogen ion concentration becomes

The new pH is
![= - log [ 10^{-6}]\\= 6](https://tex.z-dn.net/?f=%3D%20-%20log%20%5B%2010%5E%7B-6%7D%5D%5C%5C%3D%206)
