  1. Hace 4 días · It is known as a set of exactly \[6.02214076 \times {10^{23}}\] particles, which may be atoms, molecules, ions, or electrons. The mole is basically a particle count. Complete answer: The particles being counted are usually chemically similar structures that are uniquely distinct.

  2. Hace 4 días · The visible shells of circumstellar material were ejected by the central star over thousands of years. One of the richest sources for detecting interstellar molecules is Sagittarius B2 (Sgr B2), a giant molecular cloud near the centre of the Milky Way. About half of the molecules listed below were first found in Sgr B2, and many of the others ...

  3. Hace 6 días · Male contraceptive. Male contraceptives, also known as male birth control, are methods of preventing pregnancy by interrupting the function of sperm. [1] The main forms of male contraception available today are condoms, vasectomy, and withdrawal, which together represented 20% of global contraceptive use in 2019.

Shiny, raw sores or patches on the penis head. A thick, foul-smelling discharge under the foreskin or head of the penis. Swelling of the foreskin, making it harder to retract.

  5. Hace 4 días · Then the number of molecules of water and oxygen atoms present in $0.9g$ of water is $3.010 \times {10^{22}}$. So the answer is B. Note: In order to calculate these types of questions, you should always keep in mind that one mole of an atom contains an Avogadro number of particles and an Avogadro number of molecules.

  6. Hace 5 días · Such molecules with same number of carbon atoms, but varying configurations, are called isomers. Glucose, galactose and fructose are common examples of isomeric monomers. They have similar chemical formulas, i.e., similar number of atoms in the molecule, but the molecular arrangement of these atoms is different, giving rise to 3 different compounds.
