Answer:
The empirical formula=CHO. To explain it is C1H1O1 but we don't put the one that's why it is CHO
Explanation:
Answer:its A ( the transport of nutrients,water,oxygen to body cells
Explanation:
I just did it :)
Answer:
Death rates, Birth rates, and immigration rates
Explanation:
Write an balance the equation
Na2O + H2O -> 2 NaOH
Calculate the molecular mass of Na2O and NaOH from the atomic mass from the periodic table.
Na = 23
O=16
H=1
Na2O = 23 * 2 + 16 = 62
NaOH = 23+16+1= 40
For the stoichiometry of the reaction one mole of Na2O = 62g produce two mol of NaOH = 2* 40= 80 g
120 g Na2O x 80g NaOH / 62g Na2O=
154.8 g NaOH
