Vinegar does not melt ice the fastest because vinegar is largely composed of acetic acid and mostly water.The rate of melting depends on the thermal conductivity of the substance in contact with the ice cube. The higher the thermal conductivity, the quicker heat is transferred from the ice cube to the substance. Salt water has a high thermal conductivity so it would melt ice the fastest
Magnesium Hydroxide or Milk of Magnesia
Mg(OH)2
Ionic bonds.... I think ._.
Answer:
It is a chemical reaction because total mass remain unchanged.
Explanation:
A chemical reaction is represented by a chemical equation which show the reactant and products. Reactants are written on left side of arrow while products are written on right side. The number of atoms are remain same however arrangement of atoms is different on both side.
For example:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen. The number of atoms are same on both side however arrangement of atoms is different.
While in case of nuclear reaction small change in mass take place.
Hope this helps
Answer = Gravity is measured by the acceleration that gives to freely falling objects.
