Answer:
HCl + Mg(OH2) ---> MgCl2 + H2O
Explanation:
hydrochloric acid + magnesium hydroxides ==> magnesium Chloride (a salt) + Water
HCl + Mg(OH2) ---> MgCl2 + H2O
The path that planets follow around the sun are called orbitals.
Molar mass of O2= 16.0 g/mol
molar mass of H2O= 18.0 g/mol
10.0 g of O2= 5 mol
80.0 g of H20= 5 mol
you need twice as the moles of H2 as O2 so there is insufficient H2 and it is the limiting reactant and all of it will react therefore 5.00 moles of H2 with 2.5 mole of O2 to produce 5.00 moles H2O
5.00 moles of H2O is 5.00x18.00=90.00 g
so the answer is 90.00
It's the last one. They all have the same number of electrons in their outer ring. They're also called valence electrons.
Hope this helped!
Answer: Option (C) is the correct answer.
Explanation:
The elements of group 2 are also known as alkaline earth metals. Thus, each element of group 2 is an alkaline earth metal.
Group 2 contains six elements from to bottom which are as follows.
Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra). Out of which radium is a radioactive element.
