i believe the answer is B: both wind up at 60°C

but it's also reasonable to assume, given enough time, they wind up at 20°C because the water would heat up to cool the metal then slowly release the heat to the air untill they both reach 20°C

if it were me I'd answer B, apologies if I'm wrong

Explanation:

Both sodium and potassium belong to the same group. They both have only one electon in their outermost shell. But they belong to different periods. Sodium has 3 shells while potassium has 5. As the distance between the valence electron and the nucleus is more in potassium. It experience lesser pull by the nucleus and so can give away the valence electron very easily as compared to sodium which experience a greater pull from the nucleus. Thus potassium is more reactive. Reactivity increases on moving down the group.

Answer:

Sodium and potassium belongs to same group . Both has 1 electron to donate but sodium is less reactive because nuclear attraction makes it little bit difficult to loose electron as compared to potassium in which nuclear attraction becomes unable to pull the electrons towards itself . Hence we easily remove electron moreover due to screening effect also takes place .

Answer:

B.

Explanation:

Diagram B shows the repeating groups of atoms that make up the samples Marisol mixed together.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

The full ground-state electron configuration for a carbon atom is 1s² 2s² 2p².

In the first shell (principal quantum number n = 1), there is a single 1s orbital that can hold a maximum of 2 electrons. Therefore, the first two electrons in a carbon atom occupy the 1s orbital.

In the second shell (n = 2), there are two subshells available: the 2s subshell and the 2p subshell. The 2s subshell has a single 2s orbital that can hold a maximum of 2 electrons. Thus, the next two electrons occupy the 2s orbital. The remaining four electrons are distributed among the three 2p orbitals, with each orbital containing one electron. This gives carbon a total of six electrons.

The electron configuration of an atom describes the arrangement of its electrons in different energy levels and subshells. It follows the Aufbau principle, which states that electrons fill the lowest energy levels first before occupying higher energy levels. The ground-state electron configuration of carbon, 1s² 2s² 2p², indicates that carbon has two electrons in the 1s orbital, two electrons in the 2s orbital, and two electrons in the 2p orbitals.

The use of CFCs (chlorofluorocarbons) in refrigerators has a harmful effect on our atmosphere, particularly on the ozone layer.

CFCs are synthetic chemicals that were commonly used in refrigerators, air conditioners, and aerosol sprays until the 1980s when their harmful effects on the environment were discovered. When CFCs are released into the atmosphere, they rise up to the stratosphere, where they interact with ozone molecules and break them apart. This process depletes the ozone layer, which is important for protecting the earth from harmful UV radiation.

The depletion of the ozone layer can result in a range of negative effects, including increased skin cancer rates, damage to crops and ecosystems, and disruptions to the marine food chain. In addition to their effects on the ozone layer, CFCs are also potent greenhouse gases that contribute to climate change.

To address these issues, the production and use of CFCs have been largely phased out through international agreements such as the Montreal Protocol. Today, alternative refrigerants that are less harmful to the environment, such as HFCs (hydrofluorocarbons), are widely used in refrigeration and air conditioning systems.

"All zero greenhouse gas emission fuel sources are also renewable". The statement is false.

While many renewable energy sources such as solar, wind, and hydropower produce zero greenhouse gas emissions, not all zero-emission fuels are renewable.

For example, nuclear power is a zero-emission source of electricity, but it is not considered a renewable energy source because it relies on the mining and processing of non-renewable uranium.

Renewable energy sources are defined as those that can be replenished naturally and sustainably within a human timescale. These include solar, wind, hydropower, geothermal, and biomass. Zero-emission fuels refer to any fuel source that emits no greenhouse gases during use, such as hydrogen fuel cells.

While renewable energy sources often overlap with zero-emission fuels, not all zero-emission fuels are renewable. Therefore, it is important to differentiate between the two terms when discussing the sustainability and environmental impact of different energy sources.

To determine the number of grams of sulfur dioxide formed when 10.0 mol of copper(I) sulfide reacts during the process of roasting, we need to use the balanced chemical equation and the molar masses of the compounds involved.

The balanced chemical equation for the reaction of copper(I) sulfide (Cu2S) with oxygen (O2) to form copper(I) oxide (Cu2O) and sulfur dioxide (SO2) is:

2 Cu2S + 3 O2 → 2 Cu2O + 2 SO2

From the balanced equation, we can see that for every 2 moles of Cu2S, 2 moles of SO2 are formed.

Therefore, using the stoichiometry of the reaction:

10.0 mol Cu2S * (2 mol SO2 / 2 mol Cu2S) = 10.0 mol SO2

Next, we can calculate the mass of sulfur dioxide using the molar mass of SO2, which is approximately 64.06 g/mol:

Mass of SO2 = 10.0 mol SO2 * 64.06 g/mol

= 640.6 g

Therefore, when 10.0 mol of copper(I) sulfide reacts during roasting, approximately 640.6 grams of sulfur dioxide are formed.

A wastewater sample that is known to contain high amounts of acetic acid can be utilised to determine the carbon dioxide content using the titration process.

Water and some of the CO2 that is dissolved in it react to create carbonic acid (H2CO3). The pH of the water decreases as a result of the hydrogen ions in carbonic acid. Therefore, when the blood's carbon dioxide concentration increases, more H+ ions and a lower pH are created. Numerous titrations are required to boil the solution due to the CO2 that is created during the acid-base interaction. Carbonic acid (H2CO3) is created when carbon dioxide is dissolved in water; this acid acts as a buffer and reduces the accuracy of data.

The partial pressure of helium (He) in the container is 3 atm. Therefore, the correct answer is option c. 3 atm.we need to consider Dalton's law of partial pressures

To determine the partial pressure of helium (He) in the sealed container, we need to consider Dalton's law of partial pressures. According to this law, the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas.

Given that the total pressure in the container is 6 atm and equal masses of helium (He) and neon (Ne) are present, we can assume that the partial pressure of helium is equal to the partial pressure of neon.

Let's denote the partial pressure of helium as P(He) and the partial pressure of neon as P(Ne). Since the masses of He and Ne are equal, their mole ratios are also equal.

Therefore, we can write the equation:

P(He) / P(Ne) = n(He) / n(Ne)

where n represents the number of moles.

Since the mole ratios are equal, the partial pressures of He and Ne are also equal. Therefore, the partial pressure of helium is half of the total pressure:

P(He) = 6 atm / 2 = 3 atm

Non-volatile mixtures can be separated using the chromatography technique known as thin-layer chromatography (TLC).

A sheet of an inert substrate, such as glass, plastic, or aluminum foil, is used for thin-layer chromatography. This substrate is coated with a thin layer of an adsorbent material, typically silica gel, aluminum oxide (alumina), or cellulose. The stationary phase refers to this adsorbent layer.
