Answer:
A box
Explanation:
In quantum mechanics, the atom is metaphorically described as a box. In fact, the Schrödinger wave equation is based on the three dimensional box metaphor of the atom.
Thus, a box provides a convenient treatment of the atom as it represents the fundamental components of the problem of atomic structure, hence the answer.
C. A box
According to Erwin Schrödinger:He proposed the quantum mechanical model of the atom, which treats electrons as matter waves.Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were tennis balls.For example—is not possible due to quantum effects. Every atom is composed of a nucleus and one or more electrons bound to the nucleus.Thus, the correct option is C.

The reaction NO2(g) + CO(g) → NO(g) + CO2(g) has been found to be second order with respect to NO2 and zero order with respect to CO. At a certain temperature, the rate constant is found experimentally to be 3.0 × 10−5 L mol · s . What is the rate of formation
Answer:
The answer is " [tex]122.88 \times 10^{-5}[/tex]"
Explanation:
In the given question some data is missing. so, the correct solution can be defined as follows:
Missing values:
[tex]k= 3.0 \times 10^{-5}\\\\NO_2 =6.4 \ mol / l \\\\CO= 4.1 mol / l \\\\NO= 5.2 mol / l \\\\CO_2= 1.3 mol / l\\[/tex]
Given equation:
[tex]NO_2(g) + CO(g) \longrightarrow NO(g) + CO_2(g)[/tex]
In the above equation, the rate is [tex]=k.[NO_2]^2[/tex] because the above given is the part of the second-order, which relates to [tex]NO_2[/tex]. In the zeros order the Carbon monoxide (CO) its reaction doesn't affect the rate.
Calculating the rate:
Rate [tex]=k.[NO_2]^2[/tex]
[tex]= 3.0 \times 10^{-5} \times 6.4^2\\\\=3.0 \times 10^{-5} \times 40.96\\\\= 122.88 \times 10^{-5}\\[/tex]

How many pennies are in $2,020.20?
Answer:
202,020 pennies
Explanation:
The amount of pennies in 1 dollar is 100.
Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.
(2020)(100)+20= 202,000+20= 202,020 pennies.
Answer:
202,040 pennies
Explanation:
$1 is equal to 100 so just multiply 100 by 2,020 and then you can add the extra 20 cents

hello! for titration method , why is alkali used instead of bases?
Your question has been heard loud and clear.
Uhm , Alkalis are just bases who react with water. In titration we use water also , so we need bases that react with water , and such bases are alkalis.
Alkalis are a type of bases.

Time Remaining: 1:27:31 If 50.0 g of H₂ and 100.0 g of O₂ react, how many moles of H₂O can be produced in the reaction below? 2 H₂(g) + O₂(g) → 2 H₂O(g
Answer:
Explanation:
2 H₂(g) + O₂(g) → 2 H₂O(g
2 moles 1 mole 2 mole
50 g of H₂ = 50 /2 = 25 moles of H₂
100 g of O₂ = 100 / 32 = 3.125 moles of O₂
So oxygen is the limiting reagent .
3.125 moles of O₂ will react with 6.25 moles of H₂ to give 6.25 moles of H₂O .
Hence moles of H₂O produced = 6.25 moles .

What plasma looks like on the molecular level?
Explain why a liquid can flow whilst a solid retains its shape.
Answer:
A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles. It would take the shape of its container. Particles can move about within a liquid, they are packed densely enough that volume is maintained.

what do you mean by atom?
Answer:
a very small particale of matter
Explanation: something small in matter called an Atom.
Select the correct answer from each drop-down menu. An atom has 9 electrons and 9 protons at the start. If it loses 2 electrons, the net charge on the atom will be . If the atom instead gains 4 electrons, the net charge will be .
Answer:
If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.
Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.

Whats 243 daL converted to L
Number of liters (L) = 2430 L, 243 decaliters (daL) is equal to 2430 liters (L).
To convert 243 decaliters (daL) to liters (L), you need to use the conversion factor: 1 decaliter (daL) is equal to 10 liters (L).
So, to convert from daL to L, you can use the following equation:
Number of liters (L) = Number of decaliters (daL) × Conversion factor
Number of liters (L) = 243 daL × 10 L/daL
Number of liters (L) = 2430 L
Therefore, 243 decaliters (daL) is equal to 2430 liters (L).

Which describes a feature of synthetic polymers? They can be naturally decomposed. They can be cheaply recycled. They can only be made in small quantities. They can be produced at a low cost.
Answer:
The correct option is;
They can be produced at low cost
Explanation:
In comparison to several other manufacturing materials, some synthetic polymers such as plastics are more durable cost effective, flexible, faster to produce and reliable
With regards to the cost comparison, the resins used for plastic are cheaper to obtain than mining for materials such as metals. In all quantities, it is cheaper to produce and manufacture plastics than to produce metals.
Due to the light weight and corrosion resistance of plastics, it is cheaper to store and transport plastics to several locations with different environment without the plastic requiring much effort for transportation or being affected by corrosion.
