Answer: option B. closer to oxygen in the case of CO2
Explanation:
Answer:
571.81 mL
Explanation:
Assuming constant pressure, we can solve this problem by using <em>Charles' law</em>, which states that at constant pressure:
Where in this case:
We <u>input the data</u>:
- 852 mL * 200 K = V₂ * 298 K
And <u>solve for V₂</u>:
The new volume would be 571.81 mL.
Answer:
Li⁺
Explanation:
Li⁺ ions has a noble gas electron configuration because it resembles that of He.
To have a noble configuration, electrons in the outermost shell must completely fill their respective orbitals.
Li⁺ is an ion that has lost one electron from the usual number of 3 thereby remaining 2 electrons.
The electronic configuration is given as;
Li⁺ 1s²
The S orbital can hold a maximum number of just two electrons.
Helium atom has two electrons with electronic configuration of 1s²
Therefore Li⁺ = 1s² = He
A balance is used to determine mass
