# Identify the oxidation numbers for all the elements in the reactants and products for 4h2o2(aq)+cl2o7(g)+2oh−(aq)→2clo2−( aq)+5h2o(l)+4o2(g)

Identify the oxidation numbers for all the elements in the reactants and products for 4h2o2(aq)+cl2o7(g)+2oh−(aq)→2clo2−( aq)+5h2o(l)+4o2(g) identify the oxidation numbers by dragging the appropriate labels to their respective targets. -7-7 -5-5 -4-4 -3-3 -2-2 -1-1 00 +1+1 +2+2 +3+3 +4+4 +5+5 +7+7

H₂O₂: H (+1); O (-1)

Cl₂O₇: Cl (+7); O (-2)

OH⁻: O (-2); H (+1)

ClO₂⁻: Cl (+3); O (-2)

H₂O:  H (+1); O (-2)

O₂: O (0)

Explanation:

The oxidation number (o.n.) is the number of electrons an atom tends to gain or lose to form a chemical bond and gain stability.

In H₂O₂, H has the o. n. +1 (its most common o. n.) and O has the o.n. -1 in the peroxide ion O₂²⁻.In Cl₂O₇, Cl has the o.n. +7 (its highest o.n.) and O has the o.n. -2 (its most common o.n.)In OH⁻, O has the o.n -2 and H has the o.n. +1.In ClO₂⁻, Cl has the o.n. +3, and O has the o.n. -2. Cl has undergone a reduction.In H₂O, O has the o.n -2 and H has the o.n. +1.By definition, in O₂, O has the o.n. 0. It has undergone oxidation.

5. Pricing  methodology - Cost plus Mark -up

- This ensures that the price charged covers all costs related to the product,  which is good for maintaining profits.

- However the price does not consider the market demand and competition which might affect sales volumes

Explanation:

= $650,000 / 100,000 =$6.50 per machine hour

Total manufacturing cost assigned to Job 400

Direct material                                $450 Direct labor cost$210

Overheads Applied ($6.50 × 40)$260

Total manufacturing cost               $920 Unit product cost for Job 400 Unit product cost = Total Cost / Number of units completed =$920 / 52 units

= $17.6923 =$ 17.69

Selling price if Moody uses a markup percentage of 120%

Selling price  = Unit product cost × 120 %

= $17.69 × 120% =$21.23

1.    2.    3.    1. ---> B. 2. ---> C. 3. ---> A. Step-by-step-explanation:

We are three different expressions on the left side with three different products on the right side and we are supposed to match each expression with its product.

So first we will solve each of the expression and then see which product choice matches with which expression.
