Answer:
When the transfer of electrons occurs, an electrostatic attraction between the two ions of opposite charge takes place and an ionic bond is formed. A salt such as sodium chloride (NaCl) is a good example of a molecule with ionic bonding
Explanation:
magnesium + zinc oxide --> magnesium oxide + zinc
Mg + ZnO --> MgO + Zn
Reactants:
- Magnesium
- Zinc Oxide
Products:
- Magnesium oxide
- Zinc
Type of reaction: Displacement Reaction
The correct choice in the options above is the aerosols. It is because the aerosols are the ones that are combined with gaseous substances and water in order for it to be formed. Without the gaseous substance being joined with the water then the aerosols won't be produced.
Answer:
C: solvent
Explanation:
When solvent dissolve the solute it form solution. Solvent is present in large quantity while solute is present in less amount. Solution is homogeneous mixture of solvent and solute.
The rule which is followed is "like dissolve like". Polar solvent always dissolve polar solute while non polar solvent dissolve non polar substances.
Let consider the example of water and sodium chloride.
Water is polar substance it consist of H⁺ and OH⁻ ions. Sodium chloride is also polar substance it consist of Na⁺ and Cl ⁻ ions. When sodium chloride is added into the water it get dissolved because water breaks the bond between sodium and chloride and convert it into positive and negative ions. Na⁺ are surrounded by OH⁻ while Cl⁻ are surrounded by H⁺ and salt get dissolved.
