Answer:

Atmospheric water generator is used in regions that have scarcity of water or have polluted water. These generators are reliable sources of clean and safe water and hence reduces dependency on bottled water.

Atmospheric water generator extract water from the air (humid air) through condensation. Extracted water then cools down to temperature below its dew point  thereby producing potable drinking water.

Atmospheric water generator is used in regions that have scarcity of water or have polluted water. These generators are reliable sources of clean and safe water and hence reduces dependency on bottled water.

Atmospheric water generator extract water from the air (humid air) through condensation. Extracted water then cools down to temperature below its dew point  thereby producing potable drinking water.

Answer:

A device that collects water from humid ambient air is known as an atmospheric water generator. Condensation is the process of extracting water vapor from the air by chilling it below its dew point, exposing it to desiccants, or pressurizing it. An AWG, unlike a dehumidifier, is meant to make the water drinkable. Because there is nearly always a little amount of water in the air that may be collected, AWGs are useful in situations where clean drinking water is difficult or impossible to get. Cooling and desiccants are the two most common ways used.

Answer:

Acetic acid, carbonic acid and chlorous acid with calcium hydroxide

Ammonia with sulfuric acid

Explanation:

A buffer is an aqueous mixture of a weak acid and its conjugate base or vice versa.

Weak acids reacts with strong bases to produce the conjugate base. In the right amount, you can produce a buffer. In the same way, you can produce a buffer from the mixture of weak bases with strong acids.

In the problem, you have weak acids (acetic acid, carbonic acid, chlorous acid), one weak base (ammonia), one strong base (calcium hydroxide) and one strong acid (Sulfuric acid).

Thus, the mixtures that can produce a buffer are:

Acetic acid, carbonic acid and chlorous acid with calcium hydroxide

And:

Ammonia with sulfuric acid

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:

[tex]M=\frac{1.29mol}{0.350L}\\\\M=3.69M[/tex]

Which gives molar units, M, or just mol/L.

Answer:

[tex]1 {s}^{2} 2 {s}^{2} 2 {p}^{4} [/tex]

OR

[tex]2 : 6[/tex]

Answer:

If we look at the ground state (electrons in the energetically lowest available orbital) of oxygen, the electron configuration is [tex]1s^{2} 2s^{2} 2p^{4}[/tex] . If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts, the example will be the next available one. So for oxygen, it might look like this:  [tex]1s^{2} 2s^{2} 2p^{3}3s^{1}[/tex]  - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state.

So, the electron configuration of oxygen in its excited state​ is [tex]1s^{2} 2s^{2} 2p^{3}3s^{1}[/tex].

Answer:

something that can be maintained over a period of time

Answer:

a balance between meeting today's needs.......

Explanation:

Answer:

The correct answer is 0.020 M.

Explanation:

To solve this problem, we can use the equation M1V1 = M2V2, where M represents the molarity of the solution and V represents the volume of solution.  Since we are given that the original solution is 50 mL and 0.40 M, these values are V1 and M1, respectively.  The solution after dilution has a volume of 1000 mL, so this value is V2.  We are solving for the molarity after dilution, which represents M2.

If we plug in the values specified above, we get the following:

M1V1 = M2V2

(0.40 M)(50.0 mL) = (M2)(1000.0 mL)

Solving for M2, we get:

M2 = 0.020 M

Notice that our answer has 2 significant figures because 0.40 has 2 significant figures, the least of any values given in the problem.

Therefore, the answer is 0.020 M.

Hope this helps!

Answer:

the Molecular formula will be; C10H14O

Explanation:

Given the data in the question;

Chrysanthenone is an unsaturated ketone,

it has M+ = 150 and contains 2 double bond(s) and 2 ring(s).

molecular formula = ?

we know that ketone contain 1 oxygen and mass of oxygen is 16

so mass of the C and H remaining will be;

⇒ 150 - 16 = 134

Now we determine the number of C atoms;

⇒ 134 / 13 = 10

hydrocarbon with 10 hydrogen atom have CnH2n+2 means

⇒ ( 10 × 2 ) +2 = 22 hydrogens

But then we have 3 unsaturation meaning 6 hydrogens less and also we have ring meaning 2 more hydrogens

⇒ 22 - 6 - 2 = 14

Hence the Molecular formula will be; C10H14O

Answer:

Ketones and ketoacids are alternative fuels for the body that are made when glucose is in short supply. They are made in the liver from the breakdown of fats. Ketones are formed when there is not enough sugar or glucose to supply the body's fuel needs. This occurs overnight, and during dieting or fasting.

Answer:

Both reactions are acid-base reactions

Explanation:

An acid base reaction is a reaction that occurs between an acid and a base. This reaction often leads to the formation of a salt in the process. The nature of the salt depends on the type of acid and base that reacted in the process.

Both HNO3 and H2SO4 are strong acids. However, ammonia is a weak base. The acid base reaction between ammonia and these strong acids is shown below;

HNO3(aq) + NH3(aq) ------>NH4NO3(aq)

H2SO4(aq) + 2NH3(aq) ----> (NH4)2SO4(aq)

Answer: The given electronic configuration is long hand notation.

Explanation:

Long-hand notation of representing electronic configuration is defined as the arrangement of total number of electrons that are present in an element.

Noble-gas notation of representing electronic configuration is defined as the arrangement of valence electrons in the element. The core electrons are represented as the previous noble gas of the element that is considered.

The given electronic configuration of potassium (K):  

The above configuration has all the electrons that are contained in the nucleus of an element. Thus, this configuration is a long-hand notation.

25% ISOPROPANOL / H2O - 2

Pure water - 4

ISOPROPANOL / H2O - 3

Explanation:

More Isopropanol concentration is least polar. When the isopropanol is mixed with water its polarity increases. Pure water is most polar. The polarity of a substance is dependent on its ability to bent and mold in the shape as required.

Answer:

It produces free energy.

Explanation:

Photosynthesis is a process which is used by the plant for producing energy in the form of ATP. This energy is used by the plants in different activities which enables the plant to grow and develop successfully. There are some factors which causes change in the rate of photosynthesis means the production of energy for the plant body. If the environmental factors are suitable, more energy is produced through the process of photosynthesis.
