Q:

Which type of molecule is CF4?

A) nonpolar, with a symmetrical distribution of charge B) polar, with an asymmetrical distribution of charge
C) nonpolar, with an asymmetrical distribution of charge D) polar, with a symmetrical distribution of charge
 
Answer & Explanation Answer: A) nonpolar, with a symmetrical distribution of charge

Explanation:

CF4 is tetrahedral.

Since the four 'F' atoms have the same electronegativity values, there is no bias in electron distribution toward any one.

 

Therefore, electron/charge distribution is symmetrical, which also means that the molecule is nonpolar.

 

Hence, CF4 is nonpolar molecule with a symmetrical distribution of charge.

Q:

What is the output after compile and run the following code ?

int Output = 10;
boolean b = false;
if((b == true) && ((Output += 10) == 20))
{
System.out.println("We are equal " + Output);
}
else
{
System.out.println("Not equal! " + Output);
}

A) Compilation and output of "We are equal 10" B) Compilation and output of "Not equal! 10"
C) Compilation error, attempting to perform binary comparison on logical data type D) Compilation and output of "Not equal! 20"
 
Answer & Explanation Answer: B) Compilation and output of "Not equal! 10"

Explanation:

The output will be "Not equal! 10". Please note that && is logical AND operator. If first operand before (&&) is false then the other operand will not be evaluated. This illustrates that the Output +=10 calculation was never performed because processing stopped after the first operand was evaluated to be false. If you change the value of b1 to true, processing occurs as you would expect and the output would be "We are equal 20".
