what is the molecular geometry and bond angles of CF2Cl2? Is there any reason to suspect this won't be tetrahedral with bond angles of 109.5? The difference in electronegativity between F and Cl would be expected to alter the angles somewhat.
Science help plz
1. In an experiment, you remove the nucleus from an amoeba. Predict what will happen to the amoeba and explain why. plz help What does the nucleus do? Those functions would be absent. Since this is not my area of expertise, I searched Google under the key words "amoeba nu...
Math help plz ASAP.
Rationalize each denominator. 6 + square root of 2 ____________________________ square root of 3 PLZ HELP..dont kno how to do this question.plz explain..thanks You have (6 + sqrt(2))/sqrt(3) multiply that by sqrt(3)/sqrt(3) to get [(6 + sqrt(2))*sqrt(3)]/3 and simplify To rati...
