It is defined as the transitional phase of a compound or an element at the boiling temperature.It changes the state of matter from a solid or liquid to a gas.It is generally happening at a fast pace and also it needs less amount of energy.During the vaporization process, all of the water turns into a gas.During vaporization, molecules may come from below the surface of liquid also.[tex] \huge\orange{ \mid{ \underline{ \overline{ \tt EVAPORATION:}} \mid}}[/tex]
It is nothing but a special kind of vaporization and mostly occurring at the temperature below the boiling point.It changes the liquid state of the matter directly into a gas.It is generally a slower process that needs more energy.During the evaporation process, only the top level of water turn into gas.During evaporation, molecules vaporize from the surface of liquid only.➳ ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ

What happens to the pH of the solution as you add more substance to it?
Answer:
If it's a buffer solution, the pH remains unchanged.
If it's a normal solution, and an acidic substance is added to it, the pH lowers.
If a basic substance is added to it, the pH increases.
The total pressure of all the gases inside a metal container is 9.8 atm. If the partial pressure of the oxygen in the container is 4.2 atm, what is the partial pressure of the rest of the gases in the container other than the oxygen?
5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.
What is partial pressure?Each gas in a mixture adds to the overall pressure of a mixture. This portion represents the pressure. The pressure a gas would have if it were in its own volume and at its own temperature is known as the partial pressure. According to Dalton's law, the pressure distribution of an ideal gas mixture is equal to the combined partial pressures of the component gases.
The study of partial pressure is significant in the domains of physics, chemistry, and biology. The partial pressure of oxygen or carbon dioxide in the blood is used to calculate blood levels of each substance. The overall pressure in a container is equal to the sum of the partial pressures. The remaining gases must make up the remaining 5.6 atm if the oxygen partial pressure equals 4.2 atm and the sun reaches 9.8 atm in pressure.
Therefore, 5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.

What is the wavelength of spectral line resulted from the electron transition from n=3 to n=2 in a hydrogen atom.
Answer:
[tex]\lambda=6.56x10^{-7}m[/tex]
Explanation:
Hello there!
In this case, it possible to use the Rydberg equation in order to calculate the wavelength for this transition from n=3 to n=2 as shown below:
[tex]\frac{1}{\lambda} =R_H(\frac{1}{n_f^2}-\frac{1}{n_i^2} )[/tex]
Thus, we plug in the corresponding energy levels and the Rydberg constant to obtain:
[tex]\frac{1}{\lambda} =10973731.6m^{-1}(\frac{1}{2^2}-\frac{1}{3^2} )\\\\\frac{1}{\lambda} =1524129.4m^{-1}\\\\\lambda=\frac{1}{1524129.4m^{-1}} \\\\\lambda=6.56x10^{-7}m[/tex]

a) Write the word equation for the reaction of silver chlorate reacts with sodium phosphate to produce silver phosphate and sodium chlorate.
b) Write the balanced formula equation for this reaction.
c) If 287 g of silver chlorate reacts with 52.8 g of sodium phosphate, what is the maximum number of grams mass of silver phosphate will be produced?
d) Identify which reactant is the limiting reactant and which is the excess reactant.
e) How many grams of the excess reactant reacts and how many grams are left over?
Answer:
See Explanation
Explanation:
a) The word equation is;
silver chlorate + sodium phosphate ------> silver phosphate + sodium chlorate
b) The balanced reaction equation of the reaction is;
3AgClO3(aq) + Na3PO4(aq) ------->Ag3PO4(s) + 3NaClO3(aq)
c) amount of silver chlorate reacted = 287 g/191.319 g/mol = 1.5 moles
3 moles of silver chlorate yields 1 mole of silver phosphate
1.5 moles of silver chlorate yields 1.5 * 1/3 = 0.5 moles of silver phosphate
Amount of sodium phosphate reacted = 52.8 g/163.94 g/mol = 0.3 moles
1 mole of sodium phosphate yields 1 mole of silver phosphate
0.3 moles of sodium phosphate yields 0.3 moles of silver phosphate.
Hence the maximum number of grams mass of silver phosphate produced = 0.3 moles * 418.58 g/mol = 125.6 g
d) The excess reactant is silver chlorate while the limiting reactant is sodium phosphate
e) 3 moles of silver chlorate reacts with 1 mole of sodium phosphate
x moles of silver chlorate reacts with 0.3 moles of sodium phosphate
x = 3 * 0.3 = 0.9 moles of silver chlorate reacted
Mass of 0.9 moles of silver chlorate = 0.9 moles * 191.319 g/mol = 172 g of silver chlorate
Hence mass of silver chlorate left over = 287 g - 172 g = 115 g

A sample of gas as a volume of 425 mL at 25°C at and 760 tour what volume with this gas sample have at STP
Answer:
[tex]\Rightarrow V_2 = 389mL[/tex]
Explanation:
To solve this question, we could use Charles' law since both the number of mole and pressure are constant
At STP pressure P = 760 tor and Temperature = 273K
V1 =425mL, T1 =298K and T2 =273K
and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]
[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]
[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]
Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]

If I plant a green bean seed in the desert, will it grow thick, barrel-shaped stems full of water like a cactus? Why or why not?
Answer:
No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.
Each vegetation have its own characteristics and the power of adaptation. A green bean cannot survive in a desert like a cactus in desert without water. It can only grow thick in soil with proper water content and nutrients.
What is cactus?Cactus is a type of plant grow in dry regions such as deserts. It can adapt in deserts without water for long time because, the plant have enough water storage in its stem.
Domestic vegetation such as bean, pea, nuts etc ill not grow in dry regions because they cannot adapt in deserts without water. The soil in deserts is dry and have no nutrients.
These conditions prevent the growth of vegetables in desert areas. Moreover, desert have summer season only. The extreme temperature over there will cause the normal plants to diminish.
Therefore, planting green bean in deserts will not make it grow thick like a cactus plant.
