Which of the following statements are true for the reaction?

Question

Which of the following statements are true for the reaction


Ca(OH)2(aq) + HCl(aq) -->




a) Water is a product

b) When balanced the coefficient of Ca(OH)2(aq) is 1

c) Ions cannot appear in the net ionic equation because they always cancel out on both sides of the equation

d) H+(aq) appears in the net ionic equation

e) Cl -(aq) appears in the net ionic equation



Examples of species are (aq) (s) (l) etc.

Answer 1

a,b,d are correct

Answer 2

CH2=CH2 + Br2 ------------> CH2Br-CH2Br ethene bromine a million,2 dibromo ethane Which of here statements are actual ? a) The product is CH2Br-CH2Br : actual b) it incredibly is an removing reaction : fake because it quite 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 purely 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 purely all single bonds

Answer 3

(a) to (d) are true ....... (e) is false
(a) 2OH^- + 2H^+ ----> 2H2O
water exists as molecules
(b) Ca(OH)2(aq) + 2HCl(aq) --> CaCl2 (aq) + 2H2O (l)
calcium chloride floats around as ions viz. as calcium Ca^2+
ions and chloride Cl^- ions
(c) In net ionic equations, the products are either a gas, or a
precipitate or water molecules.......ions which are floating
around before and after the reaction are known as 'spectator'
ions
(d) true: as shown in (a) above
(e) Cl^- will be floating around as 'spectator' ions, and as such
they should not be included in the net ionic equation

Answer 4

A is the answer

Ca(OH)2 (aq) + 2HCl (aq) ---> CaCl2 (aq) + 2H2O (l)

thus water is a product...

Answer 5

I believe a, b and c are correct. Nobody can say that both c and either d oe e are both correct because they are contradictory.
