The most stable isotope would be lead-82.
Answer:
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.
Explanation:
Answer:
2, 3, 1, 6.
Explanation:
2H3PO4 + 3Mg(OH)2 --> Mg3(PO4)2 + 6H2O
This is a neutralisation reaction because it is the reaction between acid and base to give a salt and water.
The RHS is the first to be balanced, Mg atom is first balanced, followed by the P atom.
This is because the excess O and H atoms can be balanced on the LHS.
Using stoichiometry and the molar mass of Sr(NO2)3:
0.0091 moles Sr(NO2)3 x (211.63 g Sr(NO2)3/1 mole Sr(NO2)3) = 1.93 g Sr(NO2)3
