Arrange the following atoms in order of decreasing atomic radius:
a In, Sn, TI, Ga, Sb
b Si, S, P, As, O
c Rb, Sr, Sn, Ge, P
d Ca, Ga, Ge, Se, Te
e Li, Na, S, Si, Be

58 km per hour : d

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

i don,t know so just answer mine

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
