Answer:

Double decomposition reaction

Explanation:

When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride , water and carbon dioxide.Since HCl decomposes salts of weaker acids.

So the equation of the reaction between calcium carbonate and HCl is:

CaCO3+2HCl =CaCl2+H2O+CO2

This reaction is also known as double decomposition reaction.

lara [203]

Answer:

See Explanation ( = same answer for earlier question)

Explanation:

The Arrhenius acid-base theory defines an acid as a compound which when added into water increases the hydronium ion (H₃O⁺) concentration and the base as a compound which when added into water increases the hydroxide (OH⁻) ion concentration. As such, an acid-base reaction is limited to proton transfer to only OH⁻ ions forming water. Such would imply that all acid-base reactions produce water only in addition to a salt. This is not always the case as conjugate base anions for many substances can receive proton transfer.

Example: The reaction HOAc + NaCN => HCN + OAc-  will occur in aqueous media because the proton (H⁺) on acetic acid (HOAc) will transfer to the cyanate ion forming hydrocyanic acid (HCN). Such occurs because the CN⁻ ion is a stronger conjugate base than the acetate ion (OAc⁻) and forms the more stable weak acid.  Such is the basis of the Bronsted-Lowry Acid-Base system and states that an acid (proton donor) will transfer its ionizable hydrogen to a conjugate base (proton acceptor) if the transfer forms a weaker acid.

In nature, the chlorine atom has two isotopic forms, 35Cl and 37Cl. The masses of each form are 34.96885amu (75.76%) and 36.9659
Anni [7]

Answer:

Explanation:

mass avg = ( abundance 1 x mass 1 = abundance  2 x mass 2 )

                = (  75.76% x   34.96885  +  24.24%    x  36.9659)

                = (  0.7576 x34.96885   +   0.2424 x 36.9659  )

                    =  ( 26.49241  +     8.960534  )

                        = 35.45294 amu
