what is the daughter nucleus produced when 123in undergoes electron capture?
The daughter nucleus produced when ¹²³In undergoes electron capture is ¹²³Cd (Cadmium-123).
Electron capture is a process in which an unstable nucleus absorbs an electron from an inner electron shell, causing a proton to convert into a neutron. When ¹²³In (Indium-123) undergoes electron capture, one of its protons is transformed into a neutron, decreasing the atomic number by 1 while maintaining the same atomic mass.
As a result, the daughter nucleus produced is ¹²³Cd (Cadmium-123). Cadmium-123 has a lower atomic number (48) than Indium-123 (49) but the same mass number, reflecting the conversion of a proton to a neutron in the process.

for a given substance the entropy always increases in the following order: s (gas) < s (liq) < s (solid). (True or False)
The statement "for a given substance the entropy always increases in the following order: s (gas) < s (liq) < s (solid)" is generally true but there are exceptions.
Entropy is a measure of the degree of randomness or disorder in a system. In general, the more disorderly a system is, the higher its entropy. Therefore, for a given substance, its entropy will tend to increase as it goes from a solid to a liquid to a gas because the particles become more disordered and can move more freely.
However, there are some exceptions to this trend. For example, water is a substance that has a higher entropy in its solid form (ice) than in its liquid form. This is because the crystal structure of ice allows for more disorderly arrangements of water molecules than in liquid water. Another exception can occur when a substance undergoes a phase transition, such as melting or boiling. During these transitions, the entropy of the substance may temporarily decrease even though it eventually increases as the substance becomes more disordered in its new phase.
In summary, while the statement is generally true, there are exceptions to the trend of increasing entropy from solid to liquid to gas, and it is important to consider the specific properties of each substance when discussing its entropy.

Okay so let's answer now the question. So we have here the igneous rock. So the igneous rock, it was formed when lava or magma, okay when magma or lava solidified. So the solidification of the lava or magma resulted to the igneous rock. Now Igneous rock can be sedimentary rock. So this is our first answer. So igneous rocks and sedimentary rocks when the igneous rocks became um ah through weathering and through erosion became sediments. If the igneous rock became sediments and the sediments undergo the process of lit defecation then it will become sedimentary rock. The next rock is we have metamorphic rocks. So Igneous rock can be metamorphic rock if there is an igneous rock that will be subjected in intense he and pressure. So this heat and pressure will transform these the igneous rocks into metamorphic rock and the last time or the next. The next thing is the igneous rock can become big news rock again. Okay so if the igneous rocks will be molten again and then after the molten rocks or the lava or magma solidifies, then it becomes igneous rock. So basically this is our answer. So igneous rock can be a symptom entire Iraq if it becomes sediments through um weathering and erosion and through lift ification process it becomes sedimentary rocks. Next through intensity and pressure. Igneous rock will become metamorphic rock. Next the igneous rock can be another igneous rock. If the big news if the previous igneous rock will be subjected to heat and it will be melted and then after that it solidifies again then it becomes another igneous rock. So here we go.

how many atoms are in 2.10 g of K? molar mass of K=39.10g/mole.
Answer:
The answer is option BExplanation:
To calculate the number of atoms we must first calculate the number of moles
Molar mass = mass / number of moles
number of moles = mass / Molar mass
Molar mass (K) = 39.10mole
mass = 2.10g
number of moles = 2.10/ 39.10
= 0.0537mol
After that we use the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10^23 entities
Number of K atoms is
N = 0.0537 × 6.02 × 10^13
N = 3.23×10^22 atoms of KHope this helps you.

Explanation:
Potential energy due to gravity is given by:
PEgrav = mass • g • height
where g is the acceleration due to gravity. We'll use 9.8 N/kg (on Earth).
PEgrav = mass • g • height
PEgrav = (2 kg) • (9.8 N/kg) • (10 m)
PEgrav = 196 N*m
1 N*m = 1 Joule
PEgrav = 196 J

Calculate the molar mass of calcium phosphate. Round to the nearest hundredth.
The molar mass of calcium phosphate, when rounded to the closest tenth, is 310.18 g/mol.
To calculate the molar mass of calcium phosphate (Ca3(PO4)2), we need to add the atomic masses of each of the atoms in one mole of the compound.
The atomic masses are:
Ca (calcium): 40.08 g/mol
P (phosphorus): 30.97 g/mol
O (oxygen): 16.00 g/mol
There are three calcium atoms and two phosphate groups in one mole of calcium phosphate. Therefore, the molar mass is:
(3 x 40.08 g/mol) + (2 x (2 x 30.97 g/mol + 8 x 16.00 g/mol))
= 120.24 g/mol + 2 x (61.94 g/mol + 128.00 g/mol)
= 310.18 g/mol
Rounding to the nearest hundredth gives a molar mass of calcium phosphate of 310.18 g/mol.

_____ mass is a technique that is becoming more and more common in the study of proteins. it allows us to identify a small molecule unambiguously based on its charge to size ratio.
The technique that you are referring to is called mass spectrometry. It has become increasingly important in the study of proteins because it allows for the identification and characterization of individual molecules in complex biological samples.
Mass spectrometry works by ionizing a molecule and then measuring the mass-to-charge ratio of the resulting ions. The ions are then separated based on their mass-to-charge ratio using a mass analyzer, such as a magnetic or electric field. The resulting spectrum provides information about the mass and abundance of the different ions present in the sample.
One of the key advantages of mass spectrometry is its high sensitivity and specificity. This allows for the detection and quantification of proteins and other biomolecules at very low concentrations. Additionally, mass spectrometry can provide information about the chemical structure of the molecule, such as the presence of post-translational modifications or other covalent modifications.
Overall, mass spectrometry has become an essential tool for the study of proteins and other biomolecules in biological systems. Its ability to provide detailed information about individual molecules has revolutionized the field of proteomics and has enabled researchers to better understand the structure, function, and regulation of proteins in health and disease.
