Given that the gas inside the balloon is an ideal gas, then the ideal gas equation can be used to describe the system. I think the correct answer from the choices listed above is option B. If the balloon is heatedto a temperature of 15.5T while it is placed under a high pressure of 15.5P, then the volume of the balloon stays the same since the change in temperature corresponds to same degree of change with pressure.
Answer:
0.0928 grams of oxygen was collected.
Explanation:
Volume of oxygen gas collected = V= 75.3 mL = 0.0753 L (1 mL = 0.001 L)
Temperature of the gas = T = 25°C = 25+ 273 k = 298 K
Pressure of the gas = P - = 742 Torr - 24 Torr = 718 Torr
1 atm = 760 Torr
Moles of oxygen gas = n
Using an ideal gas equation;
n = 0.0029 mol
Mass of 0.0029 moles of oxygen gas :
0.0029 mol × 32 g/mol = 0.0928 g
0.0928 grams of oxygen was collected.
Answer:
The solid layer of fat on top protects the broth from freezer burn. When I take the broth out of the freezer I use a butter knife to pop the fat cap off before defrosting. I do save chicken fat from soup and use it instead of butter or olive oil when I cook onions.

Answer:
Heat is how hot something is and temperature is how hot OR cold something is.
