Which of the following statements is true? the angle of refracted light is equal and opposite to the angle of incoming light. a magnetic field can be created by running an electric current through a magnet. exothermic chemical reactions absorb heat. velocity and temperature are scalar quantities.

A magnetic field can be created by running an electric current through a magnet.

Explanation:

The magnetic field can be defined based on the electric and gravitational fields, which determine the changes in space due to the presence of electric or mass charges. Thus, the magnetic field is the region of space in which a magnet manifests its action. In other words, a magnetic field can be created by running an electric current through a magnet.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
