Answer: C02
The answer is CO2 because 02 is a oxygen molecule and CO is a carbon monoxide!
Answer:
D. The sun has less gravitational pull on Pluto because it is farther away.
1) Write the balanced chemical equation
4NH3 + 5O2 ----> 4NO + 6H2O
2) Write the molar ratios
4 mol NH3 : 5 mol O2 : 4 mol NO : 6 mol H2O
3) Write the proportions with the desired quantity of NO and the unknown quantity of O2
5 mol O2 / 4 mol NO = x / 18.0 mol NO
Solve for x: x = 18.0 mol NO * 5 mol O2 / 4 mol NO = 22.5 mol O2
4) Use the ideal gas equation to convert moles to volume
pV = nRT => V = nRT / p
n = 22.5 mol
R = 0.082 atm*liter / K * mol
T = 33 + 273.15 = 306.15 K
p = 874/760 atm = 1.15 atm
V = 22.5 mol * 0.082 atm*liter/K*mol * 306.15 K / 1.15 atm = 491.17 liter
Answer: 491 liters of O2
A water heater can be regularly maintained by flushing it at least two times in a year.
A water heater is a device that is used to heat up water for home use. There are different types of water heaters but they all serve the same purpose at home. In order to maintain maximum efficiency, the water heater must be maintained regularly.
The following are routine maintenance operations on a water heater;
- Inspect the heater regularly to ascertain if there are faults.
- Flush the heater at least two times each year.
- The anode rod should be changed after a couple of years

The given question is incomplete, the complete question is:
A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 18.0cm wide and 21.6cm high. The maximum safe pressure inside the vessel has been measured to be8.50MPa For a certain reaction the vessel may contain up to0.362kg of carbon dioxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius.Be sure your answer has the correct number of significant digits.
Answer:
The correct answer is 411 degree C.
Explanation:
The width of the vessel is 18.0 cm or 9.0 cm in radius and height of the vessel is 21.6 cm. In the given question, to find the volume of the cylinder, the formula to be used is pie r^2h
= 22/7 * (9)^2 * 21.6 cm^3
= 5498.7 cc
= 5.5 L
The value of 1MPa is 9.869 atm, therefore, the value of 8.5 MPa will be 83.89 atm.
The maximum safe operating temperature can be calculated by using the ideal gas equation, that is, P = nRT/V or T = PV/nR
= 83.89 atm * 5.5 L / (0.362*10^3 g/44g/mol) * 0.082 L atmK^-1mol^-1
= 683.9 K
= 683.9 - 273 = 410.9 degree C = 411 degree C.
Hence, the maximum safe operating temperature is 411 degree C.
