Answer:
c. molecular
Explanation:
2.)CH4+2O2-> CO2+2H2O
3.)N2+3H2-> 2NH3
4.)N2+O2-> 2NO
Answer:
N2+O2-> 2NO
Explanation:
An endothermic reaction refers to a reaction in which heat taken in. This implies that heat is usually absorbed by the reaction system. The enthalpy of reaction for an endothermic reaction is always positive.
The triple bond between two Nitrogen atoms in N2 gas is very strong due to its small size and the triple bond thus the nitrogen molecule has a high dissociation energy. This accounts for the large amount of energy required to break the triple bond between nitrogen atoms in the nitrogen molecule. This causes the oxidation of Nitrogen molecule to NO to be largely endothermic.
(2) temperature of the solution decreases
(3) pressure on the solution increases
(4) pressure on the solution decreases
Answer: Option (1) is the correct answer.
Explanation:
Solubility of a solute gets affected by change in temperature. That is, when we increase the temperature then more and more solute particles will dissolve into the solvent or solution.
Therefore, solubility of KClO3(s) in water increases as the temperature of the solution increases because on increasing the temperature it will completely dissociate into the solution.

An element's placement within a group on the periodic table is indicative of its electron configuration, specifically the number of valence electrons it has. As we move down a group, the principal quantum number increases, essentially moving to a higher energy level. Some elements show exceptions based on stability offered by half-filled or completely filled orbitals.
The placement of an element within a group on the periodic table has a direct correlation with its electron configuration. This connection is based on the fact that elements within the same group share the same number of valence electrons - electrons in the outermost shell of an atom that determine the chemical behavior of an element. This arrangement of elements gives the periodic table its periodic property, with recurring physical and chemical properties. An element's principal quantum number, representing the energy level of the electron, increases as we move down a group.
Although this pattern is generally accurate, there are exceptions to this rule, particularly when half-filled or completely filled orbitals can be formed which add to the atom's stability. Elements like chromium (Cr) and copper (Cu) demonstrate such anomalies.
The electron configuration of an atom, therefore, provides insights into the atom's properties, chemical behavior, and its placement on the periodic table. Understanding this connection between the location of an element on the periodic table and its electron configuration is crucial to predicting how elements will behave in chemical reactions.

The element that has the electron configuration is Darmstadtium.
Since An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ contains 110 electrons in its electron shells.
Also, the element should be a neutral atom, this number should also equal to its atomic number. Therefore, its atomic number is 110.
The element in the periodic table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transition metal.

Answer:
Darmstadtium
Explanation:
An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ has 110 electrons in its electron shells.
Since the element is a neutral atom, this number is also equal to its atomic number. Therefore, its atomic number is 110.
The element in the period table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transittion metal. It also belong to period 7 in the Periodic table of elements.
