Write the ratio; 0.43 to 0.86 as fraction in lowest terms The Correct Answer and Explanation is: To express the ratio 0.43 to 0.86 as a fraction in its lowest terms, follow these steps: So, the ratio of 0.43 to 0.86 in its lowest terms is 12\frac{1}{2}21​. Explanation: A ratio expresses a relationship between two

Explain how osmosis works and what is actually moving across the membrane and in what direction. The correct answer and explanation is: Osmosis is a process in which water molecules move across a selectively permeable membrane, from a region of lower solute concentration to a region of higher solute concentration. The selectively permeable membrane allows

6\n÷2=\n18\n9\n2)0.86\nctions. Add or Subtract the fractions.\n6\n6\n- The Correct Answer and Explanation is: Let’s break down the problem step by step. Given: 66−12\frac{6}{6} – \frac{1}{2}66​−21​ Step 1: Simplify the First Fraction The fraction 66\frac{6}{6}66​ simplifies to 111. So the equation becomes: 1−121 – \frac{1}{2}1−21​ Step 2: Subtract the Fractions To subtract these fractions, we need a

How many electrons are in the valence shell of a) H? b) Li? C) He? The correct answer and explanation is: a) Hydrogen (H) Hydrogen has an atomic number of 1, meaning it has one proton and one electron. Since it is in the first period of the periodic table, it has only one electron

how many electrons and protons does H+ have The correct answer and explanation is: An H+\text{H}^+ ion, also known as a proton, has no electrons and one proton. To explain this in detail, hydrogen (H) is the simplest element, consisting of only one proton and one electron. In its neutral state, it has an atomic
