Im not sure but my answer is c
Dmitri Mendeleev, he realized that the physical and chemical properties of elements were related to their atomic mass and arranged them into groups (columns)
The mole ratio of the compound and its constituent elements are as follows:
- The mole ratio between the compound and O is 5 : 22
- The mole ratio between the compound and Si is 2 : 4
- The mole ratio between the compound and Ca is 5 : 20
- The mole ratio between the compound and C is 1 : 1
<h3>What is mole ratio?</h3>
Mole ratio is the ratio of the moles of one or more elements or compounds to another.
The given compound is Ca₄Si₂O₆(CO₃)(OH)₂
Moles of oxygen present in 1 mole of compound = 11 moles
Moles of Si present in 1 mole of compound = 2 moles
Moles of Ca present in 1 mole of compound = 4 moles
Moles of C present in 1 mole of compound = 1 mole
- Given 5 moles of the compound below, the mole ratio between the compound and O is 5 : 22
- Given 2 moles of the compound below, the mole ratio between the compound and Si is 2 : 4
- Given 5 moles of the compound below, the mole ratio between the compound and Ca is 5 : 20
- Given 3.5 moles of the compound below, the mole ratio between the compound and C is 1 : 1
Given the equation of the reaction below;
- Pb(NO₃)₂ (aq) + 2 KI (aq) --> PbI₂ (s) + 2 KNO₃ (aq)
the mole ratio of the reactants and products are as follows:
- Pb(NO₃)₂ : 2 KI (aq) = 1 : 2
- Pb(NO₃)₂ : PbI₂ (s0 = 1 : 1
- Pb(NO₃)₂ : 2 KNO₃ (aq) = 1 : 2
In conclusion, the mole ratio of reaction is the ratio in which moles of the substances combine.

Answer:
a positive and a negative ion
Explanation:
When an acid dissolves in water, it produces positive hydrogen [H⁺] or hydronium [H₃O⁺] ions.
When a base dissolves in water, it produces negative hydroxide [OH⁻] ions.
Hope this helps.
