Well then . . . You are subtracting fractions from whole numbers. You take your whole number and put it over 1. Then Find a commom denomenator between the two bottom numbers. For example, 5-2/6. 5/1-2/6. The common denomenator is 6. So inorder to get from 1 to 6, you have to m...
5-26= -21 Negative fractions and whole numbers. If the second number is greater than the first, subtract the first from the second and add a negative sign.
They already have their maximum number of valence electrons in the outer shells, so they are stable without having to react to gaining or losing electrons
Why are the alkali and alkaline earth metals more reactive than other elements on the periodic table?
f(x)= a+tan(bx) fina a and b f(0)= 5 f(pi/8)=1/sq root of 3 +5
Scientists in 1962 became very excited when they were able to create xenon tetrafluoride. Why was this an unusual feat? Why was fluorine a good choice to try to react with xenon?
The melting point of sodium is 97.8`C. Would you expect the melting point of iodine to be higher or lower?
Yeah a little?? Thanks!
Magnesium burns quickly in flashbulbs when an electric current passes through it, providing a bright light for exposing film. Why do you suppose the inside of the bulb containing the magnesium is filled with a "noble" gas instead of air??
