Answer :

(a) The molecular equation will be,

CaCO_3(aq)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l)+CO_2(g)

(b) The complete ionic equation in separated aqueous solution will be,

Ca^{2+}(aq)+CO_3^{2-}(aq)+2H^{+}(aq)+2Cl^{-}(aq)\rightarrow Ca^{2+}(aq)+2Cl^-(aq)+H_2O(l)+CO_2(g)

(c) The net ionic equation will be,

CO_3^{2-}(aq)+2H^{+}(aq)\rightarrow H_2O(l)+CO_2(g)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

(a) The molecular equation will be,

CaCO_3(aq)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l)+CO_2(g)

(b) The complete ionic equation in separated aqueous solution will be,

Ca^{2+}(aq)+CO_3^{2-}(aq)+2H^{+}(aq)+2Cl^{-}(aq)\rightarrow Ca^{2+}(aq)+2Cl^-(aq)+H_2O(l)+CO_2(g)

In this equation, Ca^{2+}\text{ and }Cl^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

(c) The net ionic equation will be,

CO_3^{2-}(aq)+2H^{+}(aq)\rightarrow H_2O(l)+CO_2(g)

Nutka1998 [239]
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration

Which element is the excess reagent when 3.00 moles of Mg is ignited in 2.20 moles of pure oxygen
Artyom0805 [142]

Answer:

Oxygen is in excess.

Explanation:

The coefficients of the balanced equation create a mole ratio that shows the ratio of how many reactants are used up and products are created.  

The mole ratio of Mg to O2 in this equation is 2:1, which means that for every two moles of Mg used, there will be 1 mole of O2 used.

If we have 3.00 moles of Mg, we will only need 1.5 moles of oxygen to completely burn the Mg. Therefore, when all 3.00 moles of Mg are used, there will still be some of the 2.20 moles of oxygen remaining.

Analysis
Karolina [17]

The properties of substances can be used to put the into groups.

<h3>Grouping of substances</h3>

In chemistry, it is often necessary to put substances into groups based  on similarity in their properties. This is what led to the idea of a periodic table of elements.

Similarly, when we have unknown substances, we can group them according to the similarities in their properties.
