1. How to Connect four resistances values of 4 ohms 4 ohms 4 ohms and 12 ohms for an effective resistance of 6 ohms ...? 2. What is the concentration of hydrogen ions in aqueous solution with (OH) = 1x 10 negative power of 11 L mol 1 less ....? Please answer me please urgent ,,,...
1) All you need to know is that the resistors Serial and parallel addition and the reverse addition (for example, the equivalent resistance of 4 ohms resisted in the series is 4 + 4 = 8 ohms, while the equivalent resistance of 4 ohms resisted parallel is 1 / (1 / 4 ohms + 1 / 4 ohms) = 1/R_eq 1 / (2 ohms), then the equivalent resistance is 2 ohms). Try putting different combinations of resistors in series and parallel and see if you can do the equivalent resistance equal to 6 ohms. Tip: Since 12-ohms of resistance has a resistance greater than the resistance desired, must be compared with (the resistance) Other (s) 2) Remember that [H +] [] OH (molarity of hydronium and hydroxide) is always equal to 1.0 x 10 ^ -14, and clear [H +]. Hope this helps. Next time might try to check your manual, more ... often re-reading the relevant sections can give you the information you need to solve problems.
