If it’s a negative number and a positive it might be 1.4
Answer:
The order of reactivity of metals is as follows, Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Zinc > Iron > Copper > Silver > Gold.
Explanation:
The reactivity of elements (metals) towards water decreases towards the right in a period. It also increases down the group. But zinc is more reactive towards water than iron. Hence the correct order is:
Iron<Zinc<Magnesium<Sodium
The solutions vapor pressure would be lower.
Lavoisier is known as the “Father of Modern Chemistry” or the “Father of Chemistry”.
He is famous for isolating oxygen and establishing the law of conservation of mass.
