Cu2S + O2 ---> Cu2O + SO2 On the left hand side we count up all the individual atoms: Cu = 2 S = 1 O = 2 On the right hand side we do the same: Cu = 2 S = 1 O = 3 Notice we have one extra O atom on the right? To fix that we would have to have 11/2 O2 on the left hand side. Cu2S + 11/2O2 ---> Cu2O + SO2 Because you can't use fractions when balancing equations, we double the whole equation, resulting in a balanced equation with no fractions. 2Cu2S + 3O2 ---> 2Cu2O + 2SO2

Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.

atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
volume 10 was the last volume
The volume of a sphere with a radius of 11 cm is: 5,575 cm3
To calculate the volume, you have to cube the length of its side. In this case, 11 cubed.
Volume Two - Volume magazine album - was created in 1991-11.
A cube with a side length of 11 cm has a volume of 1331 cubic cm.
The volume of a cylinder 22 height and the diameter of 11 is: 2,090 cubic units.
Volume is 103.7 units3
Volume = 323.57357 units3
Volume = 287.97933 units3
A cylinder with a radius of 11 units and a height of 12 units has a volume of 4,561.59 units3
