Silver metal reacts with sulfur to form silver sulfide according to the following balanced equation: (5 points)2Ag(𝑠) + S(𝑠) → 𝐴𝑔2S(𝑠)What is the limiting reactant when 50.0 g Ag is reacted with 10.0 g S?
There is a secret organization and they
want to create a secret language for the
calculation to make the data secure.
Now the manager of the organization
asked his IT employee to make the
program which will function as follows:
a) * will subtract the numbers b) - will
divide the numbers c) / will add the
numbers d) + will multiply the numbers.
Use operator overloading.

Write a program to find if a year is a leap year or not. We generally assume that if a year number is divisible by 4 it is a leap year. But it is not the only case. A year is a leap year if −
1. It is evenly divisible by 100
2. If it is divisible by 100, then it should also be divisible by 400
3. Except this, all other years evenly divisible by 4 are leap years.
So the leap year algorithm is, given the year number Y,
● Check if Y is divisible by 4 but not 100, DISPLAY "leap year"
● Check if Y is divisible by 400, DISPLAY "leap year"
● Otherwise, DISPLAY "not leap year"
For this program you have to take the input, that is the year number from an input file input.txt that is provided to you. The input file contains multiple input year numbers. Use a while loop to input the year numbers from the input file one at a time and check if that year is a leap year or not. Your output should go in the console.
Direction: Answer the given problem.
The Guidance Counselor of your school claims that the Grade 11 students spend an average of 11.28 hours in a week doing performance tasks with standard deviation of 1.64. Your adviser thinks that students spend more time in doing performance tasks, so he decided to conduct his own research. He used a sample of 46 Grade 11 students and obtained a mean of 11.83. Is there enough evidence at 0.05 level of significance that the students spend 11.28 hours in a week doing performance tasks?
How can we identify the non-protein chemical represented in the structure as a heterotome group in a PDB file?
Cite five (5) research questions used in real life and formulate your null and alternative hypotheses.
