Answer:
Fe3O4 + 2C ---> 3Fe + 2CO2.
Explanation:
Iron 3 oxide is Fe3O4 , and the equation for the reaction is
Fe3O4 + 2C ---> 3Fe + 2CO2.
Answer:
At 15.2°C. Kinetic energy of molecules highly depends on the temperature - the warmer it is, the faster the molecules will move, especially in fluids (gases and liquids). If we consider that the formula for average kinetic energy of molecules is:
Ek = 3/2*k*T where k is Boltzmanns constant and 3/2 is, well, 3/2, kinetic energy of molecules really only depends on the temperature.
Explanation:
Answer:
Explanation:
Here, we want to calculate the number of formula units in the given molecule
We start by getting the number of moles
To get the number of moles, we have to divide the mass given by the molar mass
The molar mass is the mass per mole
The molar mass of calcium bromide is 200 g/mol
Thus, we have the number of moles as follows:
The number of formula units in a mole is:
The number of formula units in 0.2075 mole will be:
Answer:
definately substance A beacause its the lowest ph leval which means its more acidic
