Determine the compound's empirical formula and provide the formula in the space below as CxHy where x and y are the subscripts. Answer: What is the classification for this reaction? SO3(g) + H200) + H2SO4 (aq) Select one: A replacement B. oxidation reduction C. double replacement D. decomposition E. combination Write the balanced chemical equation for the description of the reaction between aqueous barium chloride and aqueous sodium sulfate to form a precipitate of barium sulfate and aqueous sodium chloride Answer:

Answer 1

sou: - Ginen composition, Carbon = 85.63% Hydrogen = 14.37%. 85. 63+ 14.37 = 100 t & morgung So, the compound is a Hydrocarbon. Atomic mass of of carbon hydrogen = 12. = 1008 Now, 85.63 = 7.135 atoms of carbon 14.37 = 14:256 atoms of hydrogen 12 1.008 Ratio of carbon and hydrogen atoms, 14.256 2 7.135 Therefore, for every atom of Carbon, there are 2 atoms of Hydrogen. . The empirical formula is [cHa] Soin :- 50₂ (9) + H₂O (1) H₂SO4 (aq.). This reaction is a simple combination reaction.

Solr - The chemical formulas are- Barium chloride - Ba Cla Sodium Sulfate - Naa S04 Barium sulfate - BaSO4 Sodium chloride - Nace The reaction thus becomes - BaSO4 d + Nace Balla + Na₂SO4 (aq) caq.) (aq) Both side of the reactions has same number of Ba,s and o atoms, but unequal Na 2 a atoms. To make them equal, let us multiply Nact on the right side by a. . The balanced reaction is- Bacha (age) + Na₂SO4 (aq) - Basoat +2 Naci (ag)
