Hope this helps you
Answer: Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. with k being a proportionality constant that depends on the amount and pressure of the gas.
Explanation:
Answer:
B) Osmosis of water molecules from unknown solution A likely caused the increase in mass observed.
Explanation:
Osmosis is a type of <em>diffusion </em>(a random movement of molecules to an area of lower concentration from an area of higher concentration) of water. Like other molecules, water can pass through a cell membrane and it will diffuse across the membrane, along its own concentration gradient independent of other particles that could be present in solution. The concentration of water in a solution is <em>inversely </em>(opposite) related to the concentration of the solute, meaning that water will move from a region of high water potential to a region of lower water potential during osmosis.
Unknown solution A had the highest water potential with a sucrose concentration of 0.0 M. This means that water diffused through the membranes of the cells in the sweet potato cube as it moved along its own <em>concentration gradient</em> (from a region of high water potential to a region of lower water potential) causing an increase in the mass of the sweet potato cube
The ionization energy is 1 × 10^-18 J
<h3>What is ionization energy?</h3>
The ionization energy is the energy required to remove an electron from an atom.
We have the following information;
wavelength of the photon = 58.4 nm
Speed of the electron = 2310 × 10^3 m/s
Since;
hv = I + 1/2mv^2
v = c/λ
hc/λ = I + 1/2mv^2
I = hc/λ - 1/2mv^2
I = (6.6 × 10^-34 × 3 × 10^8/58.4 × 10^-9) - (1/2 × 9.11 × 10^-31 × (2310 × 10^3)^2)
I = 1 × 10^-18 J
