A) Magnesium + Chlorine -> Magnesium chloride ( Mg + Cl2 -> MgCl2)
b) Potassium + Oxygen -> Potassium oxide
( 2K + O2 -> K2O )
c) Sodium + Bromine -> Sodium bromide
( 2Na + Br2 -> 2NaBr)
d) Carbon + Oxygen -> Carbon dioxide
( C + O2 -> CO2 ) This reaction occurs when heated.
The melting point of ice is 0 degrees Celcius, which means it exists as a liquid for any temperatures above 0 degrees. The melting point of salt is approximately 800 degrees Celcius, which is way greater than the melting point of ice. This means that for temperatures below 800 degrees, salt exists as a solid.
The temperature of the area where they were placed we can assume was somewhere between 0 and 800 degrees, greater than the melting point of ice but less than the melting point of salt. This why the ice melted but the salt did not.
I hope this helps!
Answer:
In 70s we were not much familiar with coca cola. Pepsi were sold in liter and milk is traditionally sold locally sold in gallon.
Explanation:
Sarah Brew said that unlike to the global brand like coca cola, Pepsi are sold at global level but milk is sold at local level follow the local custom measurement.
