Which is a product of a condensation reaction? 1. O2 2. CO2 3. H2 4. H2O
Answers
Answer:
is a product of a condensation reaction.
Explanation:
In a condensation reaction, two molecules are combined to produced a large molecules along with removal of a water molecule.
For an example, let's consider aldol condensation reaction.
In aldol condensation reaction, an enolate anion reacts and combines with an aldehyde or ketone molecule follwed by dehydration. In that dehydration step , gets removed and an unsaturated carbonyl product is formed.
Usually, are produced as a by product of a decomposition reaction.

B.iodide-53
C.iodide-127
D.iodine-127
Answers
Explanation:
1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).
2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.
3) The mass number is the sum of protons and neutrons.
4) From that, you can tell this about the four choices given:
A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.
B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)
The name iodide is reserved for the ions from iodine not for the atom.
C.iodide-127: incorrect due to the name iodide, for the same reason explained above.
D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)

A is obviously not right since it says "more order". B is incorrect because work is obligatory to make an order. If A and B are wrong, then D must be wrong. You're left with C, which is the only true statement here.

The electron cloud model, also known as the quantum mechanical model, describes electrons as existing in regions of space around the nucleus called electron orbitals or electron clouds. These electron orbitals are three-dimensional probability distributions that represent the likelihood of finding an electron at a specific location.
According to this model, electrons do not follow precise paths like planets around the sun in a classical sense. Instead, they exist in a state of probability and can be found within certain regions around the nucleus with different levels of energy. These regions are defined by the principal quantum number (n), which corresponds to the electron's energy level or shell, as well as other quantum numbers that specify the shape, orientation, and spatial distribution of the orbitals.
Electrons are considered to have both particle-like and wave-like properties, and their behavior is described by the principles of quantum mechanics. The electron cloud model provides a more accurate and comprehensive description of the behavior and distribution of electrons in an atom compared to the older Bohr model, which depicted electrons as orbiting the nucleus in specific paths.
Hence, the electrons are described by the electron cloud model.

Answer : The correct option is, 318.1 J
Solution :
The given chemical reaction will be,
In this reaction, X and Y are the reactants and W and Z are the products.
As we know that the energy remains conserved during the chemical reaction.
So,
Sum of energy of product = Sum of energy of reactant
Therefore, the amount of chemical energy of product Z contain will be, 318.1 J
Answer:
318.1 J
Explanation:
The reaction given is:
X + Y → W + Z
The chemical energy of the reaction (ΔU), is the variation of the chemical energy, so is the chemical energy of the products (UW and UZ) less the chemical energy of the reactants (UX and UY).
If the reaction loses the chemical energy, it must be negative, and the chemical energy that a substance contains, is positive.
ΔU = (UW + UZ) - (UX + UY)
-111.6 = (41.9 + UZ) - (199.3 +272.3)
-111.6 = 41.9 + UZ - 471.6
- UZ = - 429.27 + 111.6
-UZ = - 318.1
UZ = 318.1 J
