Write an equation for the reaction of magnesium oxide with sodium chloride to produce magnesium chloride and sodium oxide.

1. show the formulas of the reactants.
2. show the formulas of the products.
3. write the balanced the equation for this reaction.
4. what type of chemical reaction is this? how do you know?

Reactants:
1)Magnesium oxide: MgO
2)Sodium chloride: NaCl
Products:
1) Magnesium chloride: MgCl₂
2) Sodium oxide: Na₂O
Equation:
MgO + 2NaCl ⇒ MgCl₂ + Na₂O
The reaction is a substitution reaction because Na has replaced Mg in its oxide.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
