Answer:
0.1935atm is the pressure of the gas.
Explanation:
In the problem you have the mass of Neon (You can obtain moles using molar mass), you have volume, and temperature. You can use general ideal gas law to solve pressure:
PV = nRT
P = nRT / V
<em>Where P is pressure in atm, n are moles, R is gas constant (0.082atmL/molK), T is absolute temperature (20.0°C + 273.15 = 293.15K), and V is volume in L = Volume in dm³</em>
<em />
<em>Moles gas:</em>
Molar mass Ne = 20.1797g/mol
0.325g * (1mol / 20.1797g) = 0.0161 moles
Replacing:
P = nRT / V
P = 0.0161 moles * 0.082atmL/molK * 293.15K / 2L
P = 0.1935atm is the pressure of the gas
Answer:
if a mixture of a given percentage or ratio strength is diluted to twice its original quantity, its active ingredient will be contained in twice as many parts of the whole, and its strength therefore will be reduced by one-half
Answer:
A mixture of two or more substances that are evenly mixed throughout.
Explanation:
This is because a solution shouldn't be chemically bonded, that's called a compound.
Answer:
i am sure its the last one
Answer:
The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun. The Earth also gives off energy.
