Answer:
C.
Explanation:
Metals tends to lose electrons and form positive ions, known as cations. Whereas, non-metals tend to gain electrons and form negative ions known as anions.
Answer:
C. Metal, nonmetal
Explanation:
The metal elements tend to lose electrons and form positive ions, while the non-metal elements tend to gain electrons and form negative ions.
The mass of the solution of sugar and water is 120 grams.
Mass is the quantity of matter of a physical body.
The mass of the sugar is given is 20g
The mass of the water is 100 g.
100 + 20 = 120 gram
Thus, the mass of the solution of sugar and water is 120 grams.

Dipole-dipole type of intermolecularforce present between MgNO3 and H2O.
The positive end of one polar molecule and the negative end of another polar molecule are attracted to one another by dipole-dipole forces. Strengths of dipole-dipole forces per mole range from 5 kJ to 20 kJ.
Between molecules with permanent dipoles, there are dipole-dipole forces. These forces become stronger with increasing polarity for molecules with identical size and mass. Moreover, nonpolar molecules can develop dipoles as a result of polar molecules, producing dipole-induced dipole forces.
Hydrogen bonds form between nearby hydrogen and oxygen atoms of adjacent water molecules in the case of water. A bond called a hydrogen bond is produced by the attraction between individual water molecules.
Thus, the type of intermolecularforce between MgNO3 and H2O is Dipole-dipole.
