Answer:
The answer to your question is P2 = 1.52 atm
Explanation:
Data
Volume 1 = V1 = 4.54 l
Pressure 1 = P1 = 1.65 atm
Temperature 1 = T1 = 75°C
Volume 2= V2 = 5.33 l
Pressure 2 = P2 = ?
Temperature 2 = 103°C
Process
1.- Convert temperature to °K
Temperature 1 = 75 + 273 = 348°K
Temperature 2 = 103 + 273 = 376°K
2.- Use the combine gas law to find the final pressure
P1V1/T1 = P2V2/T2
-Solve for P2
P2 = P1V1T2 / T1V2
-Substitution
P2 = (1.65 x 4.54 x 376) / (348 x 5.33)
-Simplification
P2 = 2816.62 / 1854.84
-Result
P2 = 1.52 atm
solution:
Density of water the density of water is greatest at about four degrees C (39.2° F or 277degrees Kelvin) which is a density of 1.000 kg per liter (62.4 pounds per cubic foot). Liquids expand slightly as their temperature is raised, but liquid water is denser than solid water (ice). That is why ice floats: it is less dense than liquid water. That is due to the crystal structure of ice. When water freezes, its volume increases about nine percent. 277 K. Density rho = mass m / Volume V. Water has a density of 1,000 kg/m3 = 1,000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL at the temperature of 3.98 degrees Celsius. Temperature in degrees Celsius and the density of water: 1
At 4 °C, its density is the greatest and is equal to 1000 kilograms per cubic meter (SI unit). At any other temperature, its density is less than 1000 kilograms per cubic meter. The answer "1.0" is wrong. Water is unique in that it is one of the only substances that actually expands and becomes less dense as the temperature increases. Water molecules (H 2 O) have a special shape and arrangement; this is why ice floats above the warmer water on a frozen lake. To convert grams/cm3 or grams/mL (1 cm 3 = 1 mL) into other units, use these conversions: 1 dry ounce = 28.349 grams 1 fluid ounce = 29.574 mL so to go from grams/cm 3 to dry ounces per fluid ounce, multiply by 0.9586.
Snow is the result of moisture and low temperatures colliding; when they collide, they become tiny ice crystals. When ice crystals stick to one another, they become snowflakes. Snow is important to the water cycle because when they precipitate to the earth, they start to melt on surfaces warmer than themselves. The melted result becomes water, and when the water either seeps into the ground or flows into a source of water nearby, the water cycle's process repeats all over again.

Answer:
The volume of nitrogen oxide formed is 35.6L
Explanation:
The reaction of nitric acid with copper is:
Cu(s) + 4HNO₃ → Cu(NO₃)₂ + 2NO₂(g) + 2H₂O(l)
Moles of copper are:
Moles of nitric acid are:
As 1 mol of Cu reacts with 4 moles of HNO₃:
0.697 mol Cu × (4mol HNO₃ / 1mol Cu) = 2.79 moles of HNO₃ will react. That means Cu is limiting reactant.
Moles of NO₂ produced are:
0.697 mol Cu × (2mol NO₂ / 1mol Cu) = <em>1.394 moles of NO₂</em>
Using PV = nRT
<em>Where P is pressure (735torr / 760 = 0.967atm); n are moles (1.394mol); R is gas constant (0.082atmL/molK); T is temperature (28.2°C + 273.15 = 301.35K). </em>
Thus, volume is:
V = nRT / P
V = 1.394mol×0.082atmL/molK×301.35K / 0.967atm
V = 35.6L
<em>The volume of nitrogen oxide formed is 35.6L</em>
