Hello! I believe you are asking what a Cell wall Is.
Answer:
<em> A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.</em>
Explanation:
A cell wall is<u><em> a sturdy outer layer of protection of the plant cell. It protects the cell membrane and other organelles from the environment, bacteria, and viruses</em></u>. It is composed of cellulose, lignin, and suberin interspersed with carbohydrates and proteins.
Hope this Helps!
The mass will increase think of it being on a graph the y axis as mass and x axis as volume density would be the slope of the line so as mass increases so does volume and vise versa
Answer:
Volume of water
Initial temperature of the solution
Final temperature of the solution
Mass of NH₄Cl
Explanation:
There are two heat transfers involved in this experiment.
Heat of solution of NH₄Cl + heat lost by water = 0
q₁ + q₂ = 0
nΔH + mCΔT = 0
nΔH = -mCΔT
ΔH = -mCΔT/n
So, you must measure
- the volume of water (you will probably use its density to calculate its mass)
- the initial and final temperatures of the solution (to calculate ΔT)
- the mass of NH₄Cl (to calculate the number of moles)
You will probably assume that the specific heat capacity of the solution is the same as that of water, so you won't be measuring it.
There are 236 grams in 5.9 mole of NaOH.
