Make sure to list known values on the side. Based on the wording of the question, we know that pressure is constant and moles is constant. You can rearrange the ideal gas equation and solve for the volume.
what kind of question is this and idk
The unreactive nature of stainless steel means it does not react with the Hydrogen used in the determination of standard electrode potential so its SHE is almost 0. Moreover, it is not a good conductor of electricity.
The concentration of this acid in moles per litre : 17.41
<h3>Further explanation</h3>
Given
99.5% acetic acid
density=ρ=1.05 g/ml
Required
the concentration (mol/L)
Solution
99.5% dan density 1.05 g/ml (MW acetic acid = 60 g/mol)
Answer:
B. Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.
Explanation:
A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.
The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.
Cell walls also help plants to maintain shape and rigidity.
