Answer:
Consider your personal preferences first because the colors you use in your home need to reflect those preferences as well as fit in with your lifestyle.
Light has an influence over the colors that can make them look stunning as well as dull. Different types of light sources such as incandescent, fluorescent, halogen, or LED will affect the way a color appears.
The orientation of the room such as the direction it faces or how much natural or artificial light is available can also affect how colors will appear in the room. So, consider the room specifications as well.
Consider fixed as well as furnished elements and accessories as they too have color. Take them into consideration to ensure that camouflaging or clashing doesn’t happen.
Consider the texture of walls whether they are smooth, rough, or in between. The texture will change the appearance of the color. Smooth walls will appear lighter while rough walls will appear darker.
Consider the kind of mood you want to set in a particular room. Different colors as well as their hues and combinations emote different feelings.
Consider the finishing if the paint whether to use gloss, semi-gloss, or satin to name a few. The finish of the t will have a lot to do with the final look of your color.

Answer:
The determination of a melting point of a sample is a standard laboratory procedure and is relatively straight forward. It is used to identify a sample, establish its purity and determine the thermal stability of the sample.
If a reaction vessel initially contains an N2O4N2O4 concentration of 0. 0550 MM at 500 KK , what are the equilibrium concentrations of N2O4N2O4 and NO2NO2 at 500 KK
The concentration of NO2 is 0.054 M and that of N2O4 is 0.003 M.
Equilibrium constantThe equilibrium constant shows the extent to which reactants are converted into products.
We have the reaction; N2O4⇌2NO2 and Kp = 4.5. Setting up the ICE table, we have;
N2O4 ⇌ 2NO2
I 0. 0550 0
C -x +x
E 0. 0550 - x x
Given that;
Kp = [NO2]^2/[N2O4]
4.5= (x)^2/0. 0550 - x
4.5(0. 0550 - x) = x^2
0.2475 - 4.5x = x^2
x^2 + 4.5x - 0.2475 = 0
x=0.054 M
The concentration of the required NO2 gas at equilibrium is 0.054 M and that of N2O4 is 0.003 M.

Amy is looking for a model of the relationship between limiting factors and carrying capacity.
Which would be the best model?
A. a seesaw because when limiting factors go down, the carrying capacity goes up
B. two helium balloons because when limiting factors go up, the carrying capacity goes up
Answer:
a seesaw because when limiting factors go down, the carrying capacity goes up
Explanation:
A limiting factor is the scarcest resource that limits the growth of a population, so, when limiting factors go down, that growth is no longer limited.

What mass of zinc will completely react with 125.0 mL of a solution of nitric acid (HNO3) which has concentration of 0.850M?
The mass of zinc required to react with HNO3 is 3.45 g
What is moles of HNO3 reacting?The moles of HNO3 reacting is calculated using the formula below:
moles = concentration × volumevolume = 0.850
volume = 125.0 mL = 0.125 L
Moles of HNO3 = 0.850 × 0.125 = 0.10625 moles
Equation of reaction:
Zn + 2 HNO3 --> Zn(NO3)2 + H2
2 moles of HNO3 reacts with 1 mole of Zn.
moles of zinc reacting = 0.10625/2 = 0.053125
Mass of zinc = moles × molar mass
molar mass of Zn = 65
Mass of zinc = 0.053125 × 65
mass of Zn = 3.45 g
Therefore, the mass of zinc will completely react with 125.0 mL of a solution of nitric acid (HNO3) which has concentration of 0.850M is 3.45 g

Under what conditions do real gases behave most ideally.
Answer:
Under high temperatures and low pressure, gases behave the most ideal.
Explanation:
Low pressure reduces the effect of the finite size of real particles by increasing the volume around each particle, and a high temperature gives enough kinetic energy to the particles to better overcome the attractions that exist between real particles. (Prevents sticking.)
In summary, real gases behave more like ideal gases when they are far away from a phase boundary, (condensation or freezing).

Does water move into or out of cells that are placed in a hypotonic solution.
Answer:
Does water move in or out of a hypotonic solution?
In a hypertonic solution, the net movement of water will be out of the body and into the solution. ... In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.
Explanation:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Would it be possible to completely remove all lead ions from a solution by precipitating them with chloride why or why not.
No. It will not be possible to precipitate all lead ions from a solution by precipitating them with chloride.
Precipitation reactionsWhen a chloride salt is used to precipitate lead ions from a solution, an insoluble lead chloride salt would be formed
Pb2+ + Cl- ---> PbCl2
However, the formation of PbCl2 in an aqueous medium leads to the establishment of equilibrium between dissolved ions and undissolved solids.
PbCl2 (aq) <------> Pb2+ + Cl-
Thus, it will not be possible to completely remove all the lead ions from the solution.

Consider the following generic reaction for which k = 2. 54: 3 z q ⇄ 2 x what is the value of k for the following reaction: 4 x ⇄ 6 z 2 q.
The equilibrium constant of the second reaction is 0.155.
What is equilibrium constant?The equilibrium constant is a numerical value that shows the extent to which reactants are converted into products at a given temperature.
Now, we have the reaction; 3Z + Q ⇄ 2 X and 4 X ⇄ 6 Z + 2 Q.
In the first reaction;
K =[ X]^2/[Z]^3 Q
In the second reaction;
[Z]^6 [Q]^2/[X]^4
Let [ X]^2 = A
[Z]^3 Q = B
Then the second reaction can be;
K = (B)^2/(A)^2 = (B/A)^2
