What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. The total mass of reactants equals the total mass of products.

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

Front

What is the molecular geometry of SCl2?

Back

The molecular geometry of SCl2 is bent due to the presence of lone pairs on the central sulfur atom.

Front

What is Coulomb's law?

Back

Coulomb's law describes the force between two charged particles, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

Which atom has the greatest nuclear charge effect on valence electrons: Aluminum, Silicon, Gallium, or Indium?

Back

Indium has the greatest nuclear charge effect on its valence electrons due to its higher atomic number.

Front

What is the formula for lithium phosphate?

Back

The formula for lithium phosphate is Li3PO4.

Front

What is the molecular geometry of PH3?

Back

The molecular geometry of PH3 is trigonal pyramidal due to the presence of a lone pair on the phosphorus atom.

Front

Define valence electrons.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

What is the significance of molecular geometry in chemistry?

Back

Molecular geometry is significant because it influences molecular polarity, reactivity, phase of matter, color, magnetism, biological activity, and more.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another, involving the breaking and forming of bonds.
