Answer:
3.1 L
Explanation:
Step 1: Given data
- Mass of oxygen (m): 3.1 g
Step 2: Calculate the moles of oxygen
The molar mass of oxygen is 32.00 g/mol.
Step 3: Calculate the volume of the container
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 0.097 mol × (0.0821 atm.L/mol.K) × 390 K / 1.00 atm
V = 3.1 L
Answer:
Up to now, we have presented chemical reactions as a topic, but we have not ... A single-replacement reaction is a chemical reaction in which one element is ... single-replacement reactions will occur between two given reactants. This is ... Use the activity series to predict the products, if any, of each equation.
Explanation:
Explanation:
1) There are three sub atomic particles; protons, neutrons and electrons. Protons and Neutrons are found in the nucleus while electrons are found in orbitals outside the Nucleus.
2) No. This is not always the case. An example is sodium which has atomic mass of 23.
Atomic Mass = Neutrons + Protons
23 = Neutrons + 11
Neutrons = 23 - 11 = 12
In sodium there are 11 protons and 12 neutrons
