Here the nuclear decay of phosphorous to give S-32 is an example of beta-decay. Hence, the emitted particle is an electron. Thus, option b is correct.

The heavy unstable radioactive isotopes undergo nuclear decay by the emission of alpha or beta particle. Thus, there are mostly two types of decays, alpha decay and beta decay.

In alpha decay, the isotope emits a helium nuclei. Hence, mass number decreases by 4 units and atomic number decreases by 2 units. In beta decay, mass number does not change but atomic number increases by 1.

Here, P-32 undergo beta -decay by emitting an electron to form S -32. Hence, atomic number is increased by one. Therefore, the mission product is an electron option b.

Answer:

elements and compounds

Explanation:

Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it.

In the 13C NMR spectrum of benzil, the carbon responsible for the resonance at 194.5 ppm is the carbonyl carbon of the ketone group, which is in the middle of the molecule.

The peaks at 134.8 and 132.9 ppm are likely due to the carbons in the aromatic ring adjacent to the carbonyl group.

The carbon directly adjacent to the carbonyl group (ortho position) usually appears at higher chemical shift values (around 135 ppm), while the next carbon (meta position) usually appears at slightly lower values (around 130 ppm).

Therefore, the peaks at 134.8 and 132.9 ppm likely correspond to the ortho and meta carbons, respectively.

The other peaks at 129.8 and 128.9 ppm are due to the carbons in the aromatic ring farthest from the carbonyl group, while the peak at 194.5 ppm is due to the carbonyl carbon in the ketone group.

Answer:

.....false

Explanation:

the particles in the air are packed apart whereas the particles in steel are closely packed and sound travel faster in solids than in gasses..

Answer:

False

Explanation:

The speed of sound is quickest in mediums that have their molecules close apart.  The speed of sounds is quickest in solids, followed by liquids, and slowest in gasses.  The close the molecules are together, the quicker sound travels.  The sound would travel faster in the steel than in the air.

This is due to the fact that sound waves are compression waves.  This means that they rely on the way molecules collide with one another and act sort of like a spring.  

Fun fact: In the old days, people used to put their ears to the train tracks to see if a train is coming.  Sound moves so fast in metal that they can sense the vibrations miles before the train arrived.

1. A neutron outside a nucleus decays into a proton, electron, and antineutrino: This process is known as beta decay, and it is governed by the weak nuclear force. The weak nuclear force is responsible for interactions involving particles that undergo radioactive decay, such as the transformation of a neutron into a proton.

2. Protons and neutrons attract each other in a nucleus: This is the result of the strong nuclear force, also known as the strong interaction. The strong force is responsible for binding protons and neutrons together within the atomic nucleus. It overcomes the electromagnetic repulsion between positively charged protons and holds the nucleus together.

3. The Earth pulls on the Moon: This is an example of gravitational interaction. Gravity is responsible for the attractive force between objects with mass. In this case, the Earth's gravitational pull is responsible for the Moon orbiting around it.

4. Protons in a nucleus repel each other: This is due to the electromagnetic force, which is responsible for interactions between charged particles. Protons, being positively charged, repel each other due to the electromagnetic repulsion. It is the electromagnetic force that prevents the nucleus from collapsing under the repulsive forces between protons.

Answer: The difference between rapid combustion and spontaneous combustion...

Explanation:

Rapid combustion is a form of combustion, otherwise known as a fire, in which large amounts of heat and light energy are released, which often results in a flame.Whereas spontaneous combustion is the ignition of organic matter (e.g. hay or coal) without apparent cause, typically through heat generated internally by rapid oxidation.

EDTA (ethylenediaminetetraacetic acid) is commonly used to determine the hardness of water due to its ability to form complexes with metal ions, particularly calcium and magnesium ions.

Water hardness refers to the concentration of calcium and magnesium ions present in water. These ions can cause scaling, reduce the effectiveness of soaps, and have other negative effects. EDTA acts as a chelating agent, meaning it can bind to metal ions and form stable complexes.

In the process of determining water hardness, a known amount of EDTA solution is added to a water sample. The EDTA molecules form complexes with the calcium and magnesium ions present in the water.

The endpoint of the titration is reached when all the metal ions are complexed by the EDTA, resulting in a color change or an indicator reaching a specific endpoint.

Since the Gibbs free energy value (ΔG) is negative (-4.7 kJ/mol), the reaction 2 \(NO_{2}\)(g) yields \(N_{2}O_{4}\)(g) is spontaneous at 25°C.

Gibbs free energy, denoted as G, is a thermodynamic potential that measures the maximum reversible work that can be done by a system at constant temperature and pressure during a chemical or physical process. The formula for Gibbs free energy is:

ΔG = ΔH - TΔS

where:
ΔG = Gibbs free energy
ΔH = Enthalpy change (-57.2 kJ/mol)
T = Temperature in Kelvin (25°C = 298.15 K)
ΔS = Entropy change (-175.9 J/mol·K)

First, convert ΔS from J/mol·K to kJ/mol·K:
ΔS = -175.9 J/mol·K × (1 kJ/1000 J) = -0.1759 kJ/mol·K

Now, substitute the values into the formula and calculate ΔG:
ΔG = (-57.2 kJ/mol) - (298.15 K × -0.1759 kJ/mol·K)
ΔG = -57.2 kJ/mol + 52.5 kJ/mol
ΔG = -4.7 kJ/mol

A) CaCl2

Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a colorless crystalline solid at room temperature, highly soluble in water.

Answer:

4 Sb, 3 \(O_{2}\)

Explanation:

  On the reactant's side of the equation (the left side), there is one Antimony and one Oxygen gas molecule (\(O_{2}\)). The oxygen gas molecule is made of two atoms, so we actually have 2 oxygens on the left side. On the product's side (the right side), there are 4 antimony atoms, and 6 oxygen atoms. If we were to write it out in a certain way, it would look like this:

__Sb + __ \(O_{2}\) --> \(Sb_{4} O_{6}\)

                  1   Sb   4

                  2   O   6

  To balance this equation, those numbers on either side of the elements must equal each other. We can accomplish this with the proper coefficients. If we put a 4 in front of the antimony, it means this:

4 Sb + __ \(O_{2}\) --> \(Sb_{4} O_{6}\)

                  4   Sb   4

                  2   O   6

And the antimony is now balanced.

  Now we must balance the oxygen. There are 6 oxygens on the product's side but only 2 on the reactant's side. To fix this, simply multiply the oxygen by 3:

4 Sb + 3 \(O_{2}\) --> \(Sb_{4} O_{6}\)

              4   Sb   4

              6   O   6

3 * 2 = 6, so now oxygen is balanced, and the equation is now correct.

Explanation:

the largest cell potential when used along with a Mn/Mn2+ is Cu²⁺/Cu

A voltaic cell or galvanic cell is a battery that uses electrochemical energy produced from redox reactions to produce electricity. In this reaction, manganese is the anode and copper is the cathode.

Half-cell responses and respective cell potentials are shown below.

Mn = Mn²⁺ + 2e⁻        E°=-1.18V

Zn²⁺ +2e⁻  = Zn          E° = -0.76V

Pb²⁺ + 2e⁻ = Pb          E° -0.13

Cu²⁺ + 2e⁻ = Cu          E° 0.34

When Solving Cell Potentials

E° cell = E° cathode -E° anode

for Mn and Zn.

Mn (s) + Zn²⁺(aq)→ Mn²⁺(aq)+Zn(s)

E° cell = −0.76v−(−1.18v)=0.42v

For Mn and Pb the following applies:

Mn(s)+ Pb²⁺(aq) → Mn²⁺(aq) + Pb(s)

E° cell = −0.13v−(−1.18v)=1.05v

For Mn and Cu:

Mn(s)+ Cu²⁺(aq) → Mn²⁺(aq) + Cu(s)

E° cell = 0.34-(-1.18) = 1.52V

The Cu  happens to be the largest among the others.

The appropriate explanation for the non-metal is that the higher effective nuclear charge less will be the atomic radius.

Atomic radius typically decreases during a period from left to right. There are a few little outliers, such how the oxygen radius is a tiny bit bigger than the nitrogen radius. Protons are gradually added to the nucleus at the same time that electrons are gradually added to the main energy level. The enhanced positive charge of the nucleus gradually attracts these electrons closer to it. The size of the atoms shrinks as the strength of attraction between nuclei and electrons grows. Due to electron-electron repulsions that would otherwise result in the atom's size expanding, the effect becomes less pronounced as one proceeds further to the right in a period.

The correct answer is A. A pH of 7 say about a solution is The solution is neutral.

A pH of 7 indicates a neutral solution. The pH scale is a logarithmic scale that measures the acidity or alkalinity (basicity) of a solution. A pH value of 7 is considered neutral, which means the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the solution. In other words, the solution is neither acidic nor basic.

Acidic solutions have a higher concentration of hydrogen ions (H+), which makes them more acidic. The lower the pH value, the higher the concentration of H+ ions and the stronger the acid.
