Explanation:
Answer:
The correct answer is <u>Option</u><u>-</u><u>B</u> (Convert grams of Mg to moles)
Explanation:
In stoichiometry problems the first step is always to balance the given unbalanced chemical equation. In our case the given equation is already balanced hence, we looked for the second step.
As Niven wants to calculate the mass of MgO (which is the product) with respect to Mg (reactant) hence here comes another important rule. In such cases if one wants to compare masses of two reactants or reactant product. or product product then one should first convert the given mass into moles, also the same conversion for the second mass and then compare the moles and at last convert the moles back into mass. So, the flow chart should be like,
Mass (Mg) → Moles (Mg) : (MgO) Moles ← (MgO) Mass
After finding moles following step take place,
Moles (MgO) → Mass (MgO)
The dissolved species that are present in solution of NaClO4 are Na+ , ClO4-
<h3>Explanation</h3>
when substance dissolve in water it dissociate in ions. Some substance dissociate partially when they dissolve in water while others dissociate completely. NaClO4 is a salt which dissociate completely when it dissolve in water to give Na+ and CIO4- ions
