Assign all non-zero formal charges to the non-hydrogen atoms in the module below. All lone pairs have been drawn in.  Click to Show Image Description The image shows a one-carbon structure. A carbon atom is single-bonded to three hydrogen atoms: one above, one to the left, and one below. The carbon is also single-bonded to an oxygen atom on the right. The oxygen atom has three lone pairs shown as pairs of dots around it. The letters “Na” appear to the right of the oxygen atom. O [O] Na [Na] C [C]

Gregor has written code containing subroutines in assembly language. He uses a stack as a communication area for passing parameters and getting return values when calling the assembly language subroutines. However, his self-defined convention does not contain any guidance on register usage. Which of the following could directly result from him not strictly adhering to any register usage convention?

In the LC-2200 calling convention, the 6 general purpose registers are divided into 3 caller-saved ($t) registers and 3 callee-saved ($s) registers. The pseudocode snippet below demonstrates a sequence of function calls: main calls foo once foo calls bar 10 times int bar(int x) {   int sum = 0;   for(int i = 0; i < x; i++){         sum += i;   }   return sum;}void foo(){   int n = 0;   for(int i = 0; i < 10; i++){         int x = i * 3;         n+= bar(x);   }   printf("%d\n",n);}int main(){   int code = -1;   foo();   return code;} When the compiler is allocating registers to certain variables, which of the following allocations will provide an optimal number of saves/loads with respect to the calling convention?
