Why does power supply decrease when you add additional resistors in series? (For example, using 3 resistors in series versus 4 resistors in series) I understand that as you increase the number of resistors in series, it increases the equivalent resistance. If the equivalent resistance increases, and the voltage stays the same, then the current decreases (V=IR). Then you can say P=V^2/R, which means that the power decreases, right? But shouldn't the total power be the same as the first...

Question 1 1 pts When acetic acid and sodium bicarbonate react, why does the total mass decrease? the bubbling of the reaction mixture always causes spattering of the sodium bicarbonate which causes the overall mass to decrease. O a gas is released in the reaction so it's mass is not part of the reaction mixture after the reaction is complete some of the acetic acid gets consumed in the reaction which causes the overall mass to decrease the total mass...
