a. If 0.25 mol Na2CO3 completely reacts with excess HCl, how many moles of NaCl and CO2

will be produced, respectively?

b. If 6.02 x 1022 particles of NaBr completely react with excess Ca(OH)2, how many particles of NaOH will be produced?

c. If 204.45 g of NH3 is completed used up in the reaction, how many grams of (NH4)2SO4 will be produced?

d. If 1 mol C5H9O reacts with 2 mol O2, how many mol of CO2 will be produced?

1. List five ways by which one act to become a good Christian?

The solubility of ammonium formate,NH4HCO2 , in 100. g of water is 102 g at 0 °C and 546 g at 80 °C. A solution is prepared by dissolving NH4HCO2 in 185 g of water until no more will dissolve at 80 °C. The solution is then cooled to 0 °C. What mass of NH4HCO2 precipitates? (Assume that no water evaporates and that the solution is not supersaturated.)

2) A pair of alleles, P and p determines spot colour in the purple sea hare, an attractive sea slug that is a popular addition to a saltwater aquarium. PP and Pp sea hares have light purple spots, and pp sea hares have bright yellow spots. To avoid the environmental impact to coral reefs caused by the poorly regulated and destructive ornamental trade, a local aquarium shop owner wants to breed some sea hares to sell. Because they are attractive, yellow-spotted purple sea hares are in high demand and can be sold for more money than the drab purple sea hares. However, true-breeding yellow-spotted sea hares breed poorly (i.e. not very fertile). So, the shop owner purchases a pair of purple-spotted sea hares, and these mate and produce, in the F1, 31 purple and 9 yellow-spotted offspring (which are sold). Given these results, what is the best strategy for this breeder to produce more yellow-spotted sea hares? (hint: you need to calculate the expected frequency of the yellow-spotted offspring for both scenarios below – show your work)

Circle the best breeding strategy:

Random crosses between pairs of F1s

F1 backcross to parents

^For this question i just want to know how to calculate each expected frequency, i cant seem to figure out how to do that part!

Writing Activity 15: "What would be the effect?"

Step 1 Background: There are many societies throughout the world where citizens, do in fact, live under rules and laws at national, state, and local levels all considered "supreme." Imagine being convicted of a crime at a local level without the opportunity to appeal to a higher court to review your case. Think of the confusion that would occur if a local government allowed you to carry a gun for protection and defense against dangerous animals that attack your livestock, but state provincial officers arrest you for having that same gun in your possession.  How would you feel if a local ordinance ordered you to keep your lawn consistent in appearance with the rest of the homes in your neighborhood? Failure to comply with this ordinance results in an irrevocable tenant removal. However, you get fined by the state for water usage exceeding "drought rationing limits" that are automatically enforced when drought conditions exist within the state boundaries. You live 200 miles away from the drought stricken location.

Step 2 Question: What would be the most profound effect upon your personal life if all three levels of governments considered themselves "the supreme law of the land"?

Step 3 In a one-page Word document, describe "how and why" three areas of your life would be affected if all levels of government considered themselves "supreme."

Bring your own device or BYOD is great for some companies. I don't think every business needs to implement it or should implement it. There are inherent security risks when employees use their own devices for work related matters. They are not always on a secure network and usually have personal e-mail accounts on them as well as internet searches that may not be suitable or appropriate for business. Then there are very small companies that choose to save some money and have employees use their own device. If there are no real security threats and mainly used for email this will probably work out ok for everyone. In my current field it is just easier to use my own device even though we don't have a written policy regarding it. 

I need to expand on the above writing.

Directions: Write a letter according to the instructions below.

Wouldn't it be fun, just for a little while, to believe in Santa Claus once again? But instead of seeing Santa Claus through the eyes of a five-year-old, try to see him as you are right now. Suspend your imagination and believe. Tell yourself that Santa Claus is real and will consider your requests.

Write your letter to Santa using the persuasive writing style. Telling Santa why you want something (whether for yourself or for others) will improve your chances of receiving your request.

What are your priorities? What means more to you than anything else? If Santa could really provide anything you request, what would you honestly ask for? In other words, this assignment may turn out to be far more serious than you might at first glance think it is. Exactly what are your priorities, your values?

This paper may require a great deal of soul-searching and self-evaluation. Your letter should be at least 100 but not more than 125 words. Be certain to use correct capitalization, punctuation, and paragraph form in your letter.
