KClO3 --->KCl+3/2O2 assign oxidation states to each element on each side of the equation.(reactants and produc? KClO3 --->

marusya05 [52]

K will always have an oxidation state of +1. Now O is -2 except in peroxides, this is not a peroxide, so total charge will be -6, if you subtract the +1 of K from it, it leaves -5 charge to be neutralized by Cl in KClO3, so Cl will be +5. In the product side, K will still have the same oxdiation which is +1 and Cl would have -1. O2 will have zero. <span>Now, Cl is gaining the electrons to go from +5 to -1, so it is getting reduced while O2 is losing electrons to go from -2 to zero so it is getting oxidized.</span>

For the reaction 3ZnCO3 + 2H3PO4 —> 3H2O + 3CO2, how many miles of zinc carbonate are required to produce 3.0 mil of Zn3(PO4)

drek231 [11]

Answer:

$\boxed{ \text{9.0 mol of ZnCO$_{3}$}}$

Explanation:

(a) Balanced equation

3ZnCO₃ + 2H₃PO₄ ⟶ Zn₃(PO₄)₂ + 3H₂O + 3CO₂

(b). Calculation

You want to convert moles of Zn₃(PO₄)₂ to moles of ZnCO₃

The molar ratio is 1 mol Zn₃(PO₄)₂:3 mol ZnCO₃

$\text{Moles of ZnCO$_{3}$} =\text{3.0 mol Zn$_{3}$(PO$_{4})_{2}$ } \times \dfrac{\text{3.0 mol ZnCO$_{3}$}}{\text{1 mol Zn$_{3}$(PO$_{4}$)$_{2}$}} \\\\\\= \text{9.0 mol ZnCO$_{3}$}$

You need $\boxed{ \textbf{9.0 mol of ZnCO$_{3}$}}$ to form 3.0 mol of Zn₃(PO₄)₂.

A hydrocarbon molecule has seven carbon

Damm [24]

Answer: Option (3) is the correct answer.

Explanation:

When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.

When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.

When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.

Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
