Answer:
11 is the atomic number of alkali metal
Explanation:
The Group 1 elements are called the alkali metals. ... All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.
Answer:
5.60 Liters at STP
Explanation:
First you need the balanced reaction equation
2 H2 + O2 ====> 2 H2O
4 g of oxygen ( O<u>2</u> ) is 4/(15.999*2) moles of O2 (using periodic table)
Twice the number of moles of H2O re produced (from equation)
at STP the volume of a mole of gas is 22.4 liter/ mole
put all of this together
2 * 4 / (15.999*2) moles * 22.4 L/mole = 5.60 L
It is a single replacement reaction. Li and Mg switch places.
