The molecule is thiophosgene or CSCl₂.
As the informations given, the molecule contains 12.17 grams of carbon, 32.53 g of sulfur, and 72.19 g of chlorine.
Molar mass of carbon =12.
Molar mass of sulphur =32.
Molar mass of chlorine =35.
So on an average estimation, one mole of the molecule contains one mole of carbon atoms, one mole of Sulphur atoms and two moles of chlorine atoms. Molar mass of an element is the average weight of one mole of atoms of that element which is made average according to the variations of percentage availability of isotopes of that element on earth.
So the estimated molecule is CSCl₂ or thiophosgene.
Answer: C3H4 (Propayne) have a triple bond.
Explanation:
The hydrocarbons which having triple bond are called alkyne. The general formula of alkyne is CnH2n-2. Here, n is number of carbon atoms.
In alkyne, the number of hydrogen atom is 2 less than double the number of carbon atoms.
Thus, the compound C3H4 (Propyne) have a triple bond.
Answer:
Explanation:
The chemical test for water includes the cobalt chloride paper test. If water is present it will change from blue to pink colour. Another test is the copper sulphate test. pure form of copper sulphate is white in colour.
Copper (II) sulphate is used to test for water. We use white anhydrous copper (II) sulphate, which contains no water. If water is present, the copper (II) sulphate turns blue. A positive test for the presence of water will mean the copper (II) sulphate turns blue.
A 'spontaneous reaction' in chemistry refers to a reaction that continues on its own once started, not a reaction that starts spontaneously. A sparkler, once lit, undergoes a combustion reaction that needs no additional energy input.
The term spontaneous reaction in chemistry does not mean that a reaction starts spontaneously without any trigger. It actually refers to a reaction that, once started, continues without any additional external input. In the case of a sparkler, the initial energy to start the reaction is provided by lighting the sparkler. Once lit, the combustion reaction continues on its own, making it a spontaneous reaction.
The reactants in the sparkler (often metal powders and an oxidizing agent) are in a higher energy state than the products (typically metal oxides and heat) they form during burning. This difference in energy drives the reaction forward, making it spontaneous. The overall energy of the system decreases, which aligns with the principle of thermodynamics stating that a spontaneous process leads to a decrease in the system's free energy.

Atoms with low ionization energy form positive ions or cations more easily than atoms with high ionization energy due to less energy being required to remove an electron from the atom's valence shell.
The ease at which an atom forms a positive ion, also known as a cation, depends on its ionization energy. Ionization energy is the minimum amount of energy required to remove an electron from an atom in its ground state.
An atom with a low ionization energy will form a cation more readily than an atom with a high ionization energy. This is because it takes less energy to remove an electron from the atom's valence shell. On the other hand, atoms with a high ionization energy hold their electrons more tightly, thus it requires more energy to form a cation. This is seen in the trend across the periodic table where ionization energy increases across a period and decreases down a group due to the size and energy of the orbitals.
Sometimes, successive ionization energies or the energy necessary to remove subsequent electrons from an atom increase because core electrons, which are closer to the nucleus and thus experience a strong electrostatic attraction, are harder to remove than valence electrons.
