Is sodium hydroxide acidic basic or neutral how would you justify your answer? The Correct Answer and Explanation is: Correct Answer: Sodium hydroxide is basic. Explanation: Sodium hydroxide (NaOH) is classified as a base. This is because it dissociates in water to produce hydroxide ions (OH⁻). When a substance releases hydroxide ions into an aqueous

Using Yamane’s formula, what is the appropriate sample size for a population of 25,000 with a precision level of 5%?\n63\n345\n394\n4 The Correct Answer and Explanation is: To determine the appropriate sample size using Yamane’s formula, we apply the following equation:n=N1+N(e)2n = \frac{N}{1 + N(e)^2}n=1+N(e)2N​ Where: Given: Step-by-step calculation: n=25,0001+25,000(0.05)2n = \frac{25,000}{1 + 25,000(0.05)^2}n=1+25,000(0.05)225,000​n=25,0001+25,000(0.0025)n = \frac{25,000}{1
