A chemist is studying the effect of acid rain on the steel in bridges. why would she most likely use rate laws in this study?

1 answer:

7 0

The reaction between the acid rain and the metal comprising the bridge, in this case steel is an example of single replacement reaction which eats out the metal to produce other sorts of substance such as rusts and other deposits. She is most like to use the rate laws because this will allow her to identify up to what extent can the reaction proceed and the time it will take for all the metals to be eaten out.

____ [38]

Answer:

(a) Total units for January = 14,200

Total units for May = 23,260

(b). Conversion cost for :

January = 13,053

March = 13,660

May = 21,688

July = 11,212

Explanation:

As per the data given in the question,

Jan. May

Units to be accounted for

Beginning WIP 0 0

Started into production 14,200 23,260

Total number units 14,200 23,260

Units accounted for

Transferred out 11,100 15,400

Ending WIP 3,100 7,860

Total units 14200 15400

We can calculate the conversion cost by using following formula:

Conversion cost = Transferred out unit + (Work in process unit × conversion cost)

Material Conversion cost

Jan. 14,200 13,053 (11,100 + 3,100 × 63%)

Mar. 15,700 13,660 (12,300 + 3,400 × 40%)

May 23,260 21,688 (15,400 + 7,860 × 80%)

July 12,400 11,212 (10,200 + 2,200 × 46%)

The Bureau of Transportation Statistics Omnibus Household Survey is conducted annually and serves as an information source for t

sasho [114]

Answer:

a) For this case we have quantitative data since we have frequencies per each category.

b) For this case is better use percentages since we have frequency counts per each

c) First we need to calculate the total for the frequencies:

$Total = 44+130+165+741= 1080$ respondents

For this case we can calculate the percentage like this:

$\% Strongly_{agree} = \frac{44}{1080} *100 =4.07\%$

d) For this case the percentage of people who agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving is just 4.07% and by the other hand the rest of the people correspond to 95.93%.

$\frac{1036}{44}=23.55$

The people who are NOT strongly agree is about 24 times greater than the peopl who strongly agrees.

So we can say that we don't have a general support for the claim.

Explanation:

For this case we have the following data given:

Number of respondents that they strongly agree with the statement = 44

Number of respondents that they somewhat agree with the statement = 130

Number of respondents that they somewhat disagree agree with the statement = 165

Number of respondents that they strongly disagree agree with the statement = 741

Part a

Do the responses for this statement provide categorical or quantitative data?

For this case we have quantitative data since we have frequencies per each category.

Part b

Would it make more sense to use averages or percentages as a summary of the responses for this statement?

For this case is better use percentages since we have frequency counts per each category so then not makes sense calculate averages for this case.

Part c

What percentage of respondents strongly agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving?

First we need to calculate the total for the frequencies:

$Total = 44+130+165+741= 1080$ respondents

For this case we can calculate the percentage like this:

$\% Strongly_{agree} = \frac{44}{1080} *100 =4.07\%$

Part d

For this case the percentage of people who agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving is just 4.07% and by the other hand the rest of the people correspond to 95.93%.

$\frac{1036}{44}=23.55$

The people who are NOT strongly agree is about 24 times greater than the peopl who strongly agrees.

So we can say that we don't have a general support for the claim.

During its first year of operations, Silverman Company paid $12,240 for direct materials and $10,700 for production workers' wag

laila [671]

Answer:

$12,480

Explanation:

Given:

Amount paid for direct material = $12,240

production workers' wages = $10,700

Lease payments and utilities on the production facilities amounted = $9,700

general, selling, and administrative expenses = $3,800

Units produced = 6,800 units

Units sold = 4,200

Unit price of a unit = $7.30

Now,

Per unit Cost of production = $\frac{\textup{Total cost involved}}{\textup{Total number of units produced}}$

Per unit Cost of production = $\frac{\textup{12240+10700+9700}}{\textup{6800}}$

Per unit cost of production = $4.80

Also,

Units left in the inventory = Total units produced - Units sold

= 6,800 - 4,200

= 2,600

Thus,

Amount of finished goods inventory on the balance sheet at year-end

= units left in the inventory × Per unit cost of production

= 2,600 × $4.80

= $12,480
