It would be CH2! you’re just simplifying C4H8, 4 can go into C4 1 time (so we just say C) and 4 can go into H8 2 times (H2)
Lithium
Li → Li⁺ + e⁻
Li 1s²2s¹ → Li⁺ 1s² + e⁻
<span>This is rather a case of purification of impure copper or extraction of Cu from its alloy. You need to place the impure copper rod on the positive electrode (Anode) usualyy made of carbon rod, whereby oxidation reaction takes place: Cu (s) -------> Cu2+ (aq) + 2e- That is to say the impure cooper dissolves into solution. The copper (II) ions move to the negative electrode (cathode) usually made of pure copper rod. At the cathode, the Cu2+ ions are reduced : Cu2 (aq)+ + 2e- -----> Cu(s). That is to say the copper (II) ions are deposited as solid copper atoms onto the cu-rod electrode. In this way impure copper is deposited as pure copper onto the copper cathode</span>
The molarity of the resulting solution is 0.65 M.
<h3>Which molarity is it?</h3>
- To be able to comprehend what we mean by the molarity of a solution, we must first go back in time. We are aware that molarity refers to the concentration of the component in the solution. In this situation, it's important to be aware that the molarity can only be represented in terms of moles per litre.
- The number of moles of the gas must now be determined, and this can only be done by applying the ideal gas equation, which is what we will be able to accomplish in this issue.
PV = nRT
Pressure is P.
Volume is V.
The number of moles is n.
Gas constant R
Temperature is T
n = PV/RT
n = 0.97 * 12.7/0.082 * 306
n = 12.3/25.1
N=0.49 moles.
Number of Mole/Volume Equals Molarity of the Solution
0.49 moles/0.750 liters
= 0.65 M
