Food that contains nuts should be prepared last
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, when a liquid of a specific volume is transferred/poured from a container (in this case, beaker) to another container (in this case, graduated cylinder), the volume reduces (however insignificant), this is because parts of the water molecules will be "glued" to the interior body-part of the transferring container (beaker). Hence, the volume of liquid will be a little lesser than 100 mL when transferred into the graduated cylinder.

The balanced complete ionic equation for HI(aq) + RbOH(aq) →RbI(aq) +H2O(l) is given by;
Net ionic equation; H+(aq) + OH-(aq) → H2O(l)
<h2>Further Explanation:
</h2><h3>Balancing chemical equation:
</h3>
- Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products.
- Balancing chemical equations ensures that the law of conservation of mass is observed.
- Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reaction.
<h3>Net ionic equations </h3>
- Net ionic equations that do not include all ions that are present in the reactants and products.
- The equations only includes the ions that are involved in the reaction.
- The ions that are not involved in a chemical reaction are called spectator ions and are cancelled out while writing ionic equations.
A reaction between HI and RbOH is given by;
HI(aq) + RbOH(aq) →RbI(aq) + H2O(l)
- The ionic equation for the reaction will be;
H+(aq) + I-(aq) + Rb+(aq) + OH-(aq) → H2O(l) + Rb+(aq) + I-(aq)
- H+ changes state from aqueous to liquid, OH- changes state from aqueous to liquid, while both Rb+ and I- do not change state and thus are not included while writing the net ionic equation.
Therefore;
Net ionic equation will be;
H+(aq) + OH-(aq) → H2O(l)

Answer:
CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)
Explanation:
According to this question, sodium carbonate reacts with sulfuric acid to form aqueous sodium sulfate, carbon dioxide and water. The balanced chemical equation is as follows:
Na2CO3(aq) + H2SO4(aq) → Na2SO4(aq) + CO2(g) + H2O(l)
- Next, split compounds that are aqueous into ions.
2Na+(aq) + CO32-(aq) + 2H+(aq) + SO42-(aq) → 2Na+(aq) + SO42-(aq) + CO2(g) + H2O(l)
- Next, we cancel out the spectator ions, which are ions that remain the same in the reactants and products side of a chemical reaction. The spectator ions in this equation are 2Na+(aq) and SO42-(aq).
CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)
- Hence, the balanced ionic equation is as follows:
CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)
