A compound with a triple bond, like acetylene, is a molecule where three pairs of electrons are shared between two atoms. Acetylene contains a triple bond between its two carbon atoms. These bonds are strong, robust, and render unique properties to the compound.
A compound that contains a triple bond is a molecule in which three pairs of electrons are shared between two atoms, making it a very strong connection. An example of such a compound is acetylene (C2H2), which contains a triple bond between the two carbon atoms. The presence of triple bonds results in substances with unique properties when compared to compounds with only single or double bonds.
The triple bond in acetylene is formed by one sigma bond and two pi bonds. This means that acetylene is a more robust compound because of the strength of the triple bond. Additionally, molecules with triple bonds often have interesting chemical reactivities which make them important in various fields such as organic chemistry or industrial synthesis.

To calculate the number of moles in an experiment, you need to know the mass of the substance and its molecular weight. The number of moles is then found by dividing the mass by the molecular weight. This applies to any substance, including bromobenzene, magnesium, and benzophenone.
To calculate the number of moles of bromobenzene, magnesium, and benzophenone you will use in the experiment, we first need the molecular weights of each substance. The molecular weights determined from experimental data are crucial to this calculation. The number of moles of a compound is equal to the mass of the compound divided by its molecular mass. For example, if we consider a substance like benzene, the molecular formula is C6H6 which is derived from its empirical formula CH, and the ratio of the elements within it. Let's say you have 'm' grams of bromobenzene, 'n' grams of magnesium, and 'p' grams of benzophenone. Also, let the molecular weights of bromobenzene, magnesium, and benzophenone be 'M', 'N', and 'P' respectively. Then the number of moles of bromobenzene would be m/M, of magnesium would be n/N, and of benzophenone would be p/P. To get the exact values, you would need the specific weights of these substances in your experiment. Remember to ensure that the weights are in grams (for mass) and g/mol (for molecular weight) since the number of moles is a dimensionless quantity.

The given Lewis structure does not show valid resonance form. So,the given statement is false.
The Lewis structure is the representation of the of valence shell in the molecule.
The electron present in outermost shell and which involve in chemical bond formation is called valence electron.
Resonance is way to explain the localisation of electron in molecule where Lewis formula fails to describe.
The given statement is false because both structure shows different number of valence electron.

Answer:
true
Explanation:
because Lewis represent valid resonance
It boosts the loop's flux, which creates a voltage surrounding the loop and moves an electric current through the wire.
A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of passage of electric charge through a surface or into a control container is used to calculate it.
Electrons are moving constantly in current electricity. Direct current and alternating current are the two types of current used in electricity. Electrons travel only in the direction of direct current. Direct current is produced by batteries. Electrons move in both directions during alternating current.
Thus, It boosts the loop's flux, which creates a voltage surrounding the loop and moves an electric current through the wire.

Water has a higher boiling point than expected because D. of the strong attraction between polar water molecules.
The higher boiling point of water is due to the strong attraction between polar water molecules. Water molecules are polar because of the unequal distribution of electron density between the oxygen and hydrogen atoms, resulting in a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen atom.
Thus, these partial charges create attractive forces called hydrogen bonds between neighboring water molecules, making it difficult to separate the molecules and requiring more heat energy to overcome these attractive forces and reach the boiling point.
