My dog weighs 58.0 lbs. I put him into a bathtub containing 47.0 gallons of water when filled to the very top. After I put him in, I collected all the water that ran over the side of the tub, and found it to be equal to 1.923 gallons. (A) What is the density of my dog in grams per cubic centimeter? (B) What if next time I do this he gains 4.0 lbs. and grows big enough to displace 2.10 gallons. Will he still have the same density? Explain and prove your answer. All work must be shown , labeled , and explained in detail. Note that where applicable, superscripts (X 2 ) can be written as X^2 and subscripts (X 2 ) can be written as X_2 if it saves you time.

When I was recently living in Germany, the cost of gasoline was about 1.60 euro per liter. The most I could pump to fill up the empty tank on my VW Golf was 50.00 euro worth of gas at a time, after which amount the gas pump would shut off. This 50.00 euro worth of gas would last for about 190 km. (A) Given that the currency exchange rate was $1.00 = 1.12 euro, what was the cost of gasoline in dollars per gallon? (B) What was my gas mileage (fuel efficiency) in miles per gallon?

I wanted to make a hydrofluoric acid one day and started a chemical reaction. Can you balance the following equation for my reaction using the smallest set of whole numbers, then add together the coefficients? Don't forget to count coefficients of one. __ SF4 + __ H2O → __ H2SO3 + __ HF In other words what would the sum of my coefficients equal?

Ammonia is allowed to react with diatomic oxygen to form nitric oxide and water.

1) Write a balanced equation for this reaction.

2) Given 40.0 grams of ammonia and 50.0 grams of oxygen what is the limiting reactant?

I have a compound that contains nitrogen and oxygen, but I do not know its empirical formula. I do know it contains about 14 grams of nitrogen and 47.7 grams of oxygen. What is the most likely molecular formula?

Does anyone have experience with these? From what I can tell by looking on their websites it looks like they have the same stuff with the exception of maybe the Talkeetna area is covered more in the toursaver. Has anyone seen both of these books? What do you think? I had considered ordering both - they both seem to be a great value... but the Northern Lights coupon book is less expensive and seems to cover the same things. Any advice?

There will be 4 adults and a child who will be 4 years old. We want to travel beginning to mid September of next year. What is the best day tour of Denali National Park? What is the best cruise for Kenai Fjords National Park? And how can I get a really good deal? Does anyone know about the Alaska toursaver? Any suggestions or tips will be much appreciated....

I am getting married in September and my Grandpa is walking me down the aisle. He is such a great person and so special to me. I am having a hard time finding a song for us to dance to at the reception. Any ideas?

I am getting married in late September... a 10 a.m. - but formal ceremony. I am walking to the traditional wedding march but haven't yet decided on what music the bridal party should enter with. Any ideas?

I am getting married in September and would like to grow my hair out some and hopefully get it to thicken up. A couple of years back I went through treatments similar to radiation for a tumor and that is when this all started. Now, I get a good amount of calcium. I take my vitamins. I've tried gelatin tablets. Any other ideas??

I am getting married in the morning and having a brunch reception. Aside from the wedding cake, I plan on bagels, croissants, fruit trays, meat / cheese trays and punch. Any must have brunch dishes I am missing?
