WebH2CO3 is considered an acid because it ionizes in H+ and HCO3-. Some of the HCO3- will bond with water and form OH- and H2CO3 again. This is an equilibrium. But If we have only one HCO3- that didn't yet bonded to water and formed H2CO3 again, we will have more H+ in the medium, and it will be acid. Web13 apr. 2024 · I will explain how to solve this, and you can fill in the math. (1) Find the molecular weight of K 2 CO 3 in grams. Either look it up or add the atomic weights: 2K + C + 3O. (2) Divide the given mass of 89.3 grams by the molecular weight of K 2 CO 3. That gives the number of moles of K 2 CO 3. (3) Multiply the number of moles of K 2 CO 3 by ... five truthsWebCalculate the mass of the product formed. (round it to nearest integer value) Medium Solution Verified by Toppr Correct option is A) Following conservation of atoms of carbon, 27.6g K 2CO 3= 13827.6×12=2.4g carbon. So, mass of product forms K 2Zn 3[Fe(CN) 6] 2 =698× 1442.4=11.63g. So, integer value is 12. Was this answer helpful? 0 0 can i work while receiving state pension
