Sulfur will float, and iron will sink because each will retain its properties.
“Iron will float, and sulfur will sink because each will lose its properties” is <em>incorrect</em>. A substance will lose its properties only if it reacts to form a new substance.
“Both will float because they are physically mixed” is <em>incorrect</em>. The substances in a mixture retain their properties.
“Both will float because they react chemically” is <em>incorrect</em>. Iron and sulfur do not react at room temperature. Even if they did, the iron sulfide would sink.
Here's a hint. One of these is a liquid, one is a gas, and one is a radioactive gas. Match each of these descriptions to the right element, and tell me which one you would be most likely to be emitted from your stove.
The mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.
<h3>What is Ideal Gas Law?</h3>
The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
- Volume of the gas V = 3L
- At STP; P = 1.0atm, T = 273.15K
- Amount of gas n = ?
PV = nRT
n = PV / RT
n = ( 1.0atm × 3.00L ) / ( 0.08206 Latm/molK × 273.15K )
n = 3.00Latm / 22.41 Latm/mol
n = 0.13mol
Now, since Molar mass of brutane gas is 58.12 g/mol.
Mass = n × Molar mass
Mass = 0.13mol × 58.12 g/mol
Mass = 0.0022g
Therefore, the mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.
