Answer:
There are 0.195 moles.
Explanation:
1 mol of <em>any gas </em>under STP (meaning 1 atm and 273 K) will occupy 22.4 liters.
With the information above in mind, we can <u>calculate how many moles will occupy 4.38 liters</u>:
- 4.38 L * 1 mol / 22.4 L = 0.195 mol
In 4.38 liters of a gas at STP there will be 0.195 moles.
Answer: helium
Explanation:
Edit: im really sorry i thought i was answering a different question.
Based on the ionization energy levels of element 3, one can tell that the element is Magnesium. Magnesium has an atomic number of
12 so in a neutral atom, that means that there are 12 protons and 12 electrons. So based on the electrons, we can write the electronic configuration as:
Answer:
It increases because the less oxygen the more pressure there will be on that specific object
