Answer:
Empirical formula is KHO₃C.
Explanation:
Given data:
Percentage of potassium = 39.0%
Percentage of hydrogen = 1.01%
Percentage of carbon = 12.0%
Percentage of oxygen = 47.9%
Empirical formula = ?
Solution:
Number of gram atoms of K = 39.0/ 39 = 1
Number of gram atoms of H = 1.01 / 1.01 = 1
Number of gram atoms of O = 47.9 / 16 = 3
Number of gram atoms of C = 12 / 12 = 1
Atomic ratio:
K : H : O : C
1/1 : 1/1 : 3/1 ; 1/1
1 : 1 : 3 : 1
K : H : O :C = 1: 1 : 3 : 1
Empirical formula is KHO₃C.

Answer:
Water outside the cell will flow inwards by osmosis to attain equilibrium
Explanation:
In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.
If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.
Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.
If I'm not mistaken, it's 1:2. 1 mole of H2 = 2 moles of H. 1 mole of Cl2 = 2 moles of Cl.
