Answer:
calcium to give calcium oxide to give calcium trioxocabonate (limestone) to give carbondioxide
Answer:
Empirical formula = C₃S₂
Explanation:
Given data:
Mass of carbon = 44.0 mg (44/1000 = 0.044 g)
Mass of sulfur = 122 mg - 44.0 mg = 78 mg = 78/1000 = 0.078 g)
Empirical formula = ?
Solution:
First of all we will calculate the number of moles.
Number of moles of carbon = mass / molar mass
Number of moles of carbon = 0.044 g/ 12.01 g/mol
Number of moles of carbon = 0.0037 mol
Number of moles of sulfur:
Number of moles = mass / molar mass
Number of moles = 0.078 g/ 32,066 g/mol
Number of moles = 0.0024 mol
Now we will compare the moles:
C : S
0.0037/0.0024 : 0.0024/0.0024
1.5 : 1
C : S = 2(1.5 : 1)
C : S = 3 : 2
Empirical formula = C₃S₂
Answer:
Cuando se agrega ácido clorhídrico diluido a piezas de mármol que son carbonato de calcio, se forma cloruro de calcio, agua y gas de dióxido de carbono. ... Nota - Todos los ácidos minerales descomponen el mármol que es carbonato de calcio en sales solubles y gas de dióxido de carbono.
