Include an ICE table by using the Insert -> Table function in the text box For the following system describing a weak base A2- A2- + 2H2O 

Suppose that you are adding a node (called “node”) to the front of a list (called “front”), and then returning the updated front. The following code almost does this… what should the missing line be? struct ContactNode* addFront(struct ContactNode* node, struct ContactNode* front) { //WHAT GOES HERE? front = node; return front; }

What is the minimum sample size required to ensure a significance level of 0.05 and a power of 0.85 when the actual satisfaction rate is 70% (p = 0.70)?

A- + H2O

A certain population follows a Normal distribution with mean µ and standard deviation of 2.5. You collect data and test the hypotheses H0: µ = 1, Ha: µ ≠ 1.  In testing the hypotheses, you obtain a P-value of 0.022.  Which of the following is true?

Different operating system structures offer both benefits and drawbacks over one another, and it’s important to understand what kind of structure should be used for different use-cases. Consider the following situation: You are asked to design an OS for an electronic door lock. This lock is used to provide access control into a certain area. It connects to a wireless network, which it uses to read a database of user access permissions. Users may touch their ID card to the lock, which then reads it, consults the database, and determines if the door should open. What structure (none, simple, layered, microkernel, or modular) should you choose for its kernel? Justify.

Which of the following correctly represents the null and alternative hypotheses for the student organization’s investigation?

What is the output of the following snippet of code? #include void foobar(int* var) { int new_int = 5; *var = new_int; } void main() { int num = 8; int* ptr = # foobar(ptr); printf(“%d”,*ptr); }

C Programming II Consider the following function: //returns the length of a list. int list_len(struct node* head) { int len = 0; struct node* iter = head; while(iter != NULL) { len++; iter = iter->next; } return len; } This code compiles fine. Will it work properly or sometimes fails in a way such that the length contains the wrong data?

C Programming III Consider the following snippet of code: // Macro for using the Pythagorean theorem to compute length of unknown side. #define PYTHAG(a, b) pow((a*a + b*b), .5) //… int left = 3; int bottom = 5; float length = PYTHAG(left, bottom); What is the final line of the above program once the preprocessor has run on it and expanded the macro? (That is, prior to compilation or linking.)
