The pillar of sustainability broken by recycling electronics in India is environmental sustainability. Implementing a law that restricts electronics recycling to the US would not necessarily be the most effective solution, as it overlooks the complex global dynamics of electronic waste management.

Recycling electronics in India often involves improper disposal methods, such as burning or dismantling without proper safety measures. This leads to environmental pollution, including the release of hazardous substances into the air, soil, and water, thus violating the principle of environmental sustainability.

However, simply mandating that electronics can only be recycled in the US may not be the most optimal solution. Electronic waste is a global issue, and restricting recycling to a single country disregards the fact that electronic products are manufactured and consumed worldwide. A more comprehensive approach to addressing electronic waste would involve international cooperation, strict regulations, and monitoring of recycling practices to ensure they meet environmental standards.

Efforts should focus on improving recycling practices globally, including promoting responsible electronic waste management, developing sustainable recycling infrastructure in multiple countries, and encouraging the adoption of safe and environmentally friendly recycling practices. This approach would foster global sustainability and address the challenges associated with electronic waste disposal more effectively than a geographically limited restriction.

Answer:

German chemist G.E. Stahl

The total charge on the atom is +1 and the correct option is option 3.

According to the Bohr Atomic model, a small positively charged nucleus is surrounded by revolving negatively charged electrons in fixed orbits.

He concluded that electron will have more energy if it is located away from the nucleus whereas electrons will have less energy if it located near the nucleus.

In a neutral atom, the number of protons is equal to the number of electrons.

Since, this atom has 11 protons and 10 electrons, thus there is one extra protons which gives it a +1 charge.

Therefore, the total charge on the atom is +1 and the correct option is option 3.

Answer:

Power = Work done * time

P = (F * d) * t

P = (mg * d) * t

d = 1 step = 10 cm

30 steps = 300 cm

300 cm = 3m

P = (60*9.8 * 3) * 10

P = 17640 Watt

P = 1.764 Kilowatt

Ans: 60 watt

Explanation:

Solution

M=60kg, G=10

Distance=10*10/100

=1m

Time=10sec

Now,

W=M×G×H

=60×10×1

=600

P=w÷t

=600÷10

=60watt

Hence, the power of the man is 60watt

518.5 atm pressure of hydrogen is needed to maintain a \(H_2\) concentration of 0.42 m

The given Henry's law constant for \(H_2\) is 8.1 × 10^-4 M atm^-1 at 25°C. To find the pressure of hydrogen needed to maintain a \(H_2\) concentration of 0.42 M, we can use Henry's law.

The equation for Henry's law is:

C = kH*P

where C is the concentration of gas in moles per liter, P is the partial pressure of the gas in atmospheres, and kH is Henry's law constant in M/atm.

Plugging the values in Henry's law equation, we get:

0.42 = (8.1 × 10^-4)P

Dividing both sides by (8.1 × 10^-4), we get:

P = (0.42)/(8.1 × 10^-4)

P = 518.5 atm

Hence, the pressure of hydrogen needed to maintain a \(H_2\) concentration of 0.42 M is 518.5 atm.

Answer:

102 g Al₂O₃

Explanation:

The theoretical yield is the mass of product calculated via the molar masses and balanced chemical equation.

The limiting reagent is the reactant that is completely reacted before the other reactant(s) are used up. Since Al produces the smaller amount of product, it appears that Al is the limiting reactant. You can only make as much product as the limiting reactant allows. As such, the theoretical yield is 102 grams Al₂O₃.

I believe it is D because a combustion reaction produces carbon dioxide (CO2) and water (H2O)

The percent yield of the reaction is 64.49%.

To calculate the percent yield of a reaction, we use the following formula:

Percent yield = (actual yield / theoretical yield) x 100

In this case, the actual yield is the amount of 4-methylcyclohexene that was recovered, which is 501 mg. The theoretical yield is the amount of 4-methylcyclohexene that would have been produced if the reaction went to completion, which is the amount of 4-methylcyclohexanol that was used, or 850 μl.

First, we need to compute for the theoretical yield. The density and molecular weight of is 0.914 g/mL and 114.1855 g/mol, respectively.

850 μl (0.914 g/mL) (1 mL/1000μl) (1 mol/114.1855 g) = 6.8038 x 10⁻³ mol

Since the reaction is 1:1 reaction, meaning that one mole of starting material should yield one mole of product. 1 mol of 4-methylcyclohexanol will result to 1 mol 4-methylcyclohexene.

4-methylcyclohexene = 6.8038 x 10⁻³ mol

Multiply with its molecular weight (114.1855 g/mol).

6.8038 x 10⁻³ mol (114.1855 g/mol) = 0.7769 g

theoretical yield = 0.7769 g = 776.9 mg

Now we can plug in the values into the formula:

Percent yield = (501 mg / 776.9 mg) x 100 = 64.49%

Therefore, the percent yield of this reaction is 64.49%.

Entropy is represented by the symbol S, and a change in entropy is represented by "delta" S or ΔS. ΔS becomes positive when a system's entropy grows. ΔS becomes negative when a system's entropy diminishes.

When a process creates more molecules than it started with, entropy increases. When a process creates fewer molecules than it began with, entropy drops.

Negative delta S (S0) denotes a reduction in entropy with respect to the system. The entropy of the cosmos increases for physical processes, yet it reduces inside the bounds of the system being examined.

∆S  denotes the entropy (disorder) transition from reactants to products. R is the gas constant (always positive) T is the absolute temperature (Kelvin, always positive) What it means: If H is negative, the reaction emits heat from the reactants to the products.

The Value of X in 5g of Na2CO3.XH2O is 2.

To find the value of X in the compound Na2CO3·XH2O, we need to determine the number of water molecules (H2O) associated with each formula unit of Na2CO3. This can be done by performing a simple experiment called "dehydration."

To begin, we measure 5 grams of Na2CO3 and heat it to a high temperature. As heat is applied, the water molecules associated with the compound will evaporate, leaving behind an anhydrous form of Na2CO3. After heating, we measure the remaining mass of the compound.

Let's assume that after heating, the mass of the anhydrous Na2CO3 is found to be 3 grams. This means that 2 grams of water (H2O) were lost during the dehydration process.

To determine the value of X, we need to calculate the number of moles for both Na2CO3 and H2O. The molar mass of Na2CO3 is 106 g/mol, while the molar mass of H2O is 18 g/mol.

The number of moles of Na2CO3 can be calculated using the formula: moles = mass / molar mass. Thus, moles of Na2CO3 = 3 g / 106 g/mol = 0.0283 mol.

Since the ratio between Na2CO3 and H2O in the compound is 1: X, we can conclude that 0.0283 mol of Na2CO3 corresponds to 2 grams of water (H2O).

Now, we can set up a proportion to find the value of X:

0.0283 mol Na2CO3 / 2 g H2O = 1 mol Na2CO3 / X g H2O

Simplifying the equation, we find:

X = (2 g H2O * 0.0283 mol Na2CO3) / (0.0283 mol Na2CO3)

X = 2 g

Therefore, the value of X in the compound Na2CO3·XH2O is 2.

33.4 kilojoules of heat are necessary to melt 100 grams of ice therefore, option A is the right choice.

The heat that is required to break the intermolecular connections in a substance as it is transformed from one phase to another is referred to as the latent heat of that substance. The temperature does not rise due to the presence of latent heat.

Throughout the process of phase changeover, the temperature of the substance does not change. The amount of heat that must be applied in order to turn 1 g of solid ice into liquid is referred to as the latent heat of the fusion of ice.

Mass of ice = 100g

Latent heat of fusion of ice = 334 Joules/g

True

In an exothermic reaction, energy is released in the form of heat or light into the environment. That means the reactants have high energy, and they are unstable. Reactants will get stabilized by forming bonds and releasing energy. As exothermic reactions are bond-making processes, so the energy is released and reactants have more energy and are highly reactive. Thus, the products formed in exothermic reactions will have less energy as compared to reactants. Therefore, the given statement is True.

Radiocarbon dating is used to determine the age of an object.

Radiocarbon dating is a method used to estimate the age of organic materials based on the decay of radioactive carbon-14 isotopes. This technique is widely employed in archaeology, geology, and other scientific fields. When living organisms, such as plants or animals, are alive, they maintain a ratio of carbon-14 to stable carbon-12 isotopes.

However, once they die, the carbon-14 begins to decay at a known rate. By measuring the remaining carbon-14 and comparing it to the initial ratio, scientists can calculate the time that has passed since the organism's death. This method is particularly useful for dating objects that are up to around 50,000 years old. Palynology is the study of pollen grains, taphonomy focuses on the process of decay and fossilization, and paleontology deals with the study of fossils but not specifically dating methods.
