Question

Which of the following statements are true for the reaction


Ca(OH)2(aq) + HCl(aq) →



a) Water and a salt are the products


b) This is an elmination reaction


c) When balanced, the stoichiometric coefficient of HCl is one


d) The pH of the resulting solution would be seven

Answer 1

a) true: water and CaCl2 (a type of salt) are the products
b) false.: this ais a double displacement reaction
c) false: it will be 2.
d) true: Ca(OH)2 is a strong base, and HCl is a strong acid.

Answer 2

CH2=CH2 + Br2 ------------> CH2Br-CH2Br ethene bromine a million,2 dibromo ethane Which of here statements are real ? a) The product is CH2Br-CH2Br : real b) that's an removing reaction : fake because it fairly is an addition reaction c) CH2=CH2 is an alkyne :fake as ethene is an alkene, an alkyne has a C-C triple bond d) The product will incorporate in undemanding terms double bonds : fake because of the fact the C-C double bond opens as much as accomodate the two Br atoms coming in (including), so as that the product has in undemanding terms all single bonds
