Romashka-Z-Leto [24]

Answer:

Ca(aq)⁺²  + CO₃⁻²(aq) → CaCO₃(s)

Explanation:

Breaking down the equation into ionic form gives:

2Na⁺(aq) + CO₃⁻²(aq) + Ca⁺²(aq) + 2NO₃⁻¹ (aq)  →  2Na⁺(aq) + 2NO₃⁻¹(aq)  + CaCO₃(s)

Eliminating all the same ionic states on both sides of the equation gives following final equation

Ca(aq)⁺²  + CO₃⁻²(aq) → CaCO₃(s)

gizmo_the_mogwai [7]

Answer:

26.16 moles of water

Explanation:

As per balanced equation given:

6CO_{2}+6H_{2}O--->C_{6}H_{12}O_{6}

Six moles carbon dioxide will react with six moles of water to give one mole of glucose

As per problem the moles of glucose produced = 4.36

so the moles of water required is = 6X4.36 =26.16 moles

the same number of moles of carbon dioxide will also be required.
