Answer:
The correct option is;
True
Explanation:
The noble gases are the group 18 elements, all of which are monoatomic gases, located in the extreme right of the periodic table. Due to their filled outermost or valence shells,and their nonreactive nature, the noble gases where initially known as inert gases.
The noble gases have very low melting points and boiling points as hey have very weak inter atomic forces between their atoms such that they all appear as gases under standard atmospheric temperature and pressure conditions.
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.
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.

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]

which of the following resources can replenish themselves by quick recycling and replacement , within a reasonable time , if managed properly?
plz say the answer with explanation
options
A. coal
B. soil
C. natural gas
D. sunlight
Answer:
B
Explanation:
Among all the answers soil is the only renewable resource.
Both coal and natural gas are a non-renewable resource
Even though sunlight can be used for solar panels as a renewable resource but when the sun dies out from burning there is no replacement for it.
Hence, only answer is soil

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.

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).

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 .
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

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.
