1. YYouhave ice at 263 K (-10.0 oC) and 1.0 atm. What could you do to make the ice sublime?
2. A sample of dry ice (solid CO2) is cooled to 173 K (-100.0 oC), and is set on a table at room
temperature (298 K; 25 oC). At what temperature is the rate of sublimation and deposition the same (assume that
pressure is held constant at 1 atm)?
3. What are the significant differences between the phase diagrams of water and carbon dioxide? Discuss
each briefly.
Calculate the volume of hydrogen gas produced at STP when 30g of Zn is added to dilute hydrochloric acid at 33⁰c and 775mmHg pressure (H=1 , Zn=65 , cl =35.5) molar mass of gas at STP= 22.4 dm³
Given that 45.6 mL of a 0.453 M potassium iodide solution reacts with 0.355 M lead (ll) nitrate solution, what volume of lead (ll) nitrate is required for complete precipitation?
Pb(NO3) + 2 Kl —> Pbl2 + 2KNO3
What is the mass of dextrose that is in 45.6 g of a 10.3% solution of dextrose?
Define a function PrintValue() that takes two integer parameters and outputs the sum of all integers starting with the first and ending with the second parameter, followed by a newline. The function does not return any value.
Ex: If the input is 1 4, then the output is:
10Note: Assume the first integer parameter is less than the second.
Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7:
42 seconds
Define a function CalcPyramidVolume() with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. CalcPyramidVolume() calls the given CalcBaseArea() function in the calculation.
Relevant geometry equations:
Volume = base area x height x 1/3
(Watch out for integer division).
Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output:
FIXME: Finish GetUserNum()
FIXME: Finish GetUserNum()
FIXME: Finish ComputeAvg()
Avg: -1Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main():
int main() {
double milesPerHour;
double minutesTraveled;
double hoursTraveled;
double milesTraveled;
cin >> milesPerHour;
cin >> minutesTraveled;
hoursTraveled = minutesTraveled / 60.0;
milesTraveled = hoursTraveled * milesPerHour;
cout << "Miles: " << milesTraveled << endl;
return 0;
}Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that outputting 'endl' outputs a newline. Ex: PrintFeetInchShort(5, 8) prints:
5' 8"Hint: Use \" to print a double quote.
