The formula will be AI2O3
Answer:
Explanation:
% yields = <u>experimental yields</u> / theoretical yields )x 100%
=( 302 ÷ 320 )x 100% = 94.4 %
% error = 100% - 94.37% 5.64%
or u can use this law :
% error =(theoretical value - experimental value )/ theoretical value) x 100%
( 320 - 302 )/ 320 ) x 100% = 5.64%
HBrO2 is weaker than HClO2.
Since we have the mass of the iron ingot we can get its volume by dividing the mass (4.578) by the density of iron (7874 kgm^-3) and we get that the volume is 5.8140716x10^-4 m^3. now we convert the volume from m^3 to cm^3(1m^3=1000000cm^3) and so by multiplying 5.8140716x10^-4 by <span>1000000 we get:581.4cm^3 (1 decimal place).
the volume for any cuboid is V=l x w x s we have the volume, the length and the width, so we plug in the values and solve for s
</span>

the answer is rounded to three significant figures
hope i helped
