The coefficient for H2O in an equation represents the number of water molecules. In this case, the coefficient for 4H2O would mean there are 4 water molecules present.
Adding a big 2 in front of a formula typically means squaring the formula. For example, if the original formula was x, then 2x would mean squaring x, which is x^2.
if you mean carbon dioxied, the formula is: CO2 If you mean carbon monoxied, the formula is: CO If you mean Carbon Dioxide, the formula is: CO2 If you mean Carbon Monoxide, the formula is: CO [Corrections for spelling only]
The correct formula for lead (Pb) with a +4 charge and oxygen (O) with a -2 charge is PbO2, which is lead(IV) oxide.
The chemical formula for tin(IV) hydroxide is Sn(OH)4.
The coefficient for H2O in an equation represents the number of water molecules. In this case, the coefficient for 4H2O would mean there are 4 water molecules present.
The formula for cadmium hydrogen sulfate is Cd(HSO4)2.
Do you mean the molecular formula? If so, then it is C4H10. If you mean empirical formula, then it is C2H5.
2Ag20 --> 4Ag + 02 Fe304 + 4H2 --> 4H20 + CuCl2
CHCl3 is the chemical formula of trichloromethane (chloroform); the meaning of 4 is four molecules.
Adding a big 2 in front of a formula typically means squaring the formula. For example, if the original formula was x, then 2x would mean squaring x, which is x^2.
Formula for finding the surface area of a sphere = 4*pi*radius2 in square units. Formula for finding the volume of a sphere = 4/3*pi*radius3 in cubic units. Or did you mean the formula for finding the area of a square? in which case it is Length*Height in square units.
Add together all 4 sides if you mean a parallelogram
A formula does not normally have a mean!
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
The geometric mean of two numbers is the square root of their product. For example, the geometric mean of 4 and 25 is 10.
You need to explain what you mean by '4 mb'.
