Answer:
True! Under most conditions, they are usually the same.
This is because to balance out the negativity or positivity of an atom, the opposite joins in.
Hope this helps.
Answer:
Number of moles of CoCl3 = 0.09 moles
Explanation:
Given data:
Mass of CoCl₃ = 12.1 g
Number of moles = ?
Solution:
First of all we will calculate the molar mass.
Molar mass of CoCl3 = 28.01 + (35.5×3)
Molar mass of CoCl3 = 28.01 + 106.5
Molar mass of CoCl3 = 134.51 g/mol
Number of moles of CoCl3 = mass / molar mass
Number of moles of CoCl3 = 12.1 g/134.51 g/mol
Number of moles of CoCl3 = 0.09 moles
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
Answer:
CH4+ 2Cl2→CH2Cl2+ 2HCl
Explanation:
mass is 132.8`125
as methane and dichlormethane has the same molar ration 1 to 1
mol of ch4 is 1.5625
so 1.5625 times mr of ch2cl2 is 132.8125
