Explanation:
First conversion factor: moles of SO₄ per mole of Al₂(SO₄)₃.
3 mol SO₄ / mol Al₂(SO₄)₃
Second conversion factor: moles of S per mole of SO₄.
1 mol S / mol SO₄
Altogether:
(3 mol SO₄ / mol Al₂(SO₄)₃) × (1 mol S / mol SO₄) = 3 mol S / mol Al₂(SO₄)₃
Answer:
Xenon
Explanation:
Step 1: Given data
- Pressure (P): 1.00 atm (I looked it up)
Step 2: Convert the temperature to Kelvin
K = °C + 273.15 = 100.0°C + 273.15 = 373.2 K
Step 3: Calculate the number of moles (n)
We will use the ideal gas equation.
P × V = n × R × T
n = P × V / R × T
n = 1.00 atm × 0.335 L / (0.0821 atm.L/mol.K) × 373.2 K
n = 0.0109 mol
Step 4: Calculate the molar mass of the gas
M = 1.44 g / 0.0109 mol = 132 g/mol
Step 5: Identify the gas
The gas with a molar mass of about 132 g/mol is xenon.
The organic meaning in chemistry is natural containing carbon.
<u><em> Explanation</em></u>
The natural matter or compounds which contain carbon are referred to as organic compounds.
Example of organic compound is protein which are made up of amino acid.
Amino acid is made up of carbon, hydrogen oxygen and nitrogen atoms.
A prediction is not based upon evidence or reliable tests. A prediction is a guess as to what will happen in the future. Forecasts for example are nothing more than prediction, as even with "meteorological evidence", nothing is ever truly sure when in regard to wheather.
So "A"
Arianna has discovered a substance that is a liquid at room temperature. Through testing, she finds that it ignites quickly and burns easily, but does not dissolve in water.
How would you classify the substance? What use might it have?
