In this equation what should be the coefficients of the reactant and products I2+O2->i4O9

The correct answer is C.

For the equations to be balanced, the coefficients must make the number of atoms of the reactants and products the same across the equation. The other answer options leave the reactants having too many atoms and the product lacking. So the only properly balanced option is answer choice C.

So the completed balanced equation is:
4I2 + 9O2 -> 2I4O9

I hope this helps! :)

Answer:

solicited the bank’s client.

Explanation:

In order for Lisa to have committed solicitation and violated Standard VI(a), she must have actively searched for the bank's former client.

Josiah emptied his piggy bank and discovered he had 35 coins consisting of dimes and nickels. If the total amount of money he ha

anastassius [24]

Answer:

$d+n=35\\0.10d+0.05n=3.30$

Explanation:

Multiple Choices aren't given, so I will just solve this.

Josiah had "d" dimes and "n" nickels.

There are a total of 35 coins, nickels and dimes.

The value of "d" dimes and "n" nickels is $3.30

Note: Value of nickels is 0.05 and dimes is 0.10 (in dollars)

The system of equations (2) we can use to solve this will be:

1) an equation involving total number of coins

2) an equation stating the value of each coin and total value

Equation 1:

$d + n = 35$

Equation 2:

$0.10d+0.05n=3.30$

These are the 2 equations that can be solved simulataneously to find the number of nickels and dimes.

The electric utility rate for a facility during the months of May through October is 4.5 cents per kilowatt-hour for energy, $11

Minchanka [31]

Answer: $11564

Explanation:

Total units consumed for August = 96000

There's a peak demand of 624kw

Also, the May through October is 4.5 cents per kilowatt-hour for energy.

The August electric bill will then be:

= 96000 × 4.5/100 + 624 × 11.50 + 68

= (96000 × 0.045) + (624 × 11.50) + 68

= 4320 + 7176 + 68

= 11564

3. A company manufactures two types of products: A and B. Three resources R1, R2, and R3 are required to make these products. a.

mojhsa [17]

Answer:

(i)The units of production of Product A and B (x and y) are the decision variables

(ii)Objective is to maximize profit

(iii)Objective function, Max P=20x+50y

(iv)The Contraints are:

8x+2y $\leq$ 500....(i)

2x+5y $\leq$ 400.......(ii)

3y $\leq$ 180

x>0, y>0

Explanation:

Let the number of Product A=x

Let the number of Product B=y

Each unit of product A requires 8 units of R1 and 4 units of R2.

Each unit of product B requires 2 units of R1, 5 units of R2, and 3 units of R3

The availabilities of resources R1, R2, and R3 are 500, 400, and 180

Since R1 $\leq$ 500,

Product A requires 8 units of R1 per production unit

Product B requires 2 units of R1 per production unit

Total Unit of R1 possible is given by the inequality: 8x+2y $\leq$ 500....(i)

Since R2 $\leq$ 400,

Product A requires 2 units of R2 per production unit

Product B requires 5 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 2x+5y $\leq$ 400....(ii)

Since R3 $\leq$ 180,

Product B requires 3 units of R2 per production unit

Total Unit of R2 possible is given by the inequality: 3y $\leq$ 180....(iii)

Since the manufacturer also makes a profit of $20 and $50 for products A and B, our objective is to maximize profit

Therefore: Objective function, Max P=20x+50y ......(iv)

Suppose Amazon.com has offered you free shipping on your next purchase of more than $35. This offer is an example of ________.

Lunna [17]

Answer: Option A

Explanation: Sales promotion is the method of convincing a prospective consumer to buy the commodity. Sales promotion is intended to be used as a brief-term tool to boost sales – it is seldom appropriate as a way to develop long-term customer retention.

Giving discount, rebates and other such special offers are some of the many examples of sales promotion. In simple words,it is done to boost the sales for the current period.

In the given case, Amazon is also offering money saving offers to attract customers. Hence we can conclude that this is an example of sales promotion.
