answer:The molecules in a liquid are close together, resulting in strong intermolecular forces that maintain a fixed volume. However, these forces are not strong enough to hold the molecules in a fixed arrangement, allowing them to slide past each other and conform to the shape of their container.

answer:Unbalanced full reaction: {eq}S_2O_3^2{-}(aq) + Cu^2{+}(aq) longrightarrow S_4O_6^2{-}(aq) + Cu^{+}(aq){/eq} Oxidation half-reaction: {eq}S_2O_3^2{-}(aq) longrightarrow S_4O_6^2{-}(aq) + 2e^{-}{/eq} Reduction half-reaction: {eq}Cu^2{+}(aq) + e^{-} longrightarrow Cu^{+}(aq){/eq} Balancing in basic conditions: Add OH- ions to balance H+ ions: {eq}2OH^{-}(aq) + 2S_2O_3^2{-}(aq) + 2Cu^2{+}(aq) + 2e^{-} longrightarrow S_4O_6^2{-}(aq) + 2e^{-} + 2Cu^{+}(aq) + H_2O(l){/eq} Final balanced equation: {eq}2OH^{-}(aq) + 2S_2O_3^2{-}(aq) + 2Cu^2{+}(aq) longrightarrow S_4O_6^2{-}(aq) + 2Cu^{+}(aq) + H_2O(l){/eq}

answer:The Sieve of Eratosthenes is an efficient way to find prime numbers because it only requires you to check each number once. It is also relatively easy to implement, making it a popular choice for finding prime numbers. The Sieve of Eratosthenes is a method for finding prime numbers. It works by iteratively marking off multiples of each prime number, starting with 2. The process is as follows: 1. Create a list of all numbers from 2 to n, where n is the largest number you want to check. 2. Start with the first number in the list, 2, and mark off all its multiples in the list. 3. Move on to the next unmarked number in the list, 3, and mark off all its multiples in the list. 4. Continue this process until you have reached the square root of n. 5. Any unmarked numbers in the list are prime numbers.

answer:Tia likely entered the following in box #2 of the flowchart: "Hepatitis B spreads through contact with infected bodily fluids, including during childbirth or through close physical contact with an infected individual." Explanation: Hepatitis B, caused by the hepatitis B virus (HBV), primarily affects the liver and can manifest with symptoms such as abdominal pain, jaundice, and dark urine. The infection can be treated with antiviral medications. Transmission occurs primarily when an individual comes into contact with the bodily fluids of an infected person, for instance, during childbirth, through sexual contact, or sharing needles. Thus, option A accurately reflects the mode of transmission described in the flowchart.
