I am 23, and a full time student, with no income just lones and grants.

My boyfriend is unemployed for the year of 2013 with no income. We both live with his father and he is the only one working in the household. Can he claim our 1 year old child on his tax return? What should we know.

She has been collecting allamony sence they seperated. If he dies is she out of luck or can she collect any social security? Its her first and only husband. They were married for 26 years and seperated in 1986. She has got allamony sence seperation.. He might die in the next week or so. What are her options as without the 500 a month she will not make it.

5. A sample of water vapor occupies a volume of 10.5 L at 200C and 100.0 kPa.

What volume will the water vapor occupy when it is cooled to 27C if the

pressure remains constant?

6. What is the volume occupied by 0.355 mole of nitrogen gas at STP?

7. What is the volume of a container that holds 25.0 g of carbon dioxide gas

at STP?

1. A sample of argon gas is at a pressure of 1.24  104 kPa and a temperature of

24C in a rigid 25-L tank. How many moles of argon does this tank contain?

2. A 35.0-L tank contains 7.00 mol of compressed air. If the pressure inside the

tank is 500.0 kPa, what is the temperature of the compressed gas?

3. How many grams of helium does a 25.0-L balloon contain at 102.0 kPa and

24C?

4. Calculate the volume that 2.25 mol of O2(g) will occupy at STP.

1. In your own words, explain hydrogen bonds.

3. Explain why the density of ice at 0°C is less than the density of liquid water at 0°C.

few practice questions need help with

1. The volume of a gas at 155.0 kPa changes from 22.0 L to 10.0 L. What is the

new pressure if the temperature remains constant?

2. Is it possible for a balloon with an initial pressure of 200.0 kPa to naturally

expand to four times its initial volume when the temperature remains

constant and atmospheric pressure is 101.3 kPa?

3. Exactly 10.0 L of O2 at 25C is heated to 100.0C. What is the new volume if

the pressure is kept constant?

4. A gas at a pressure of 501 kPa and a temperature of 25C occupies a volume

of 5.2 L. When the gas is heated to 100.0C the volume increases to 7.00 L.

What is the new pressure?

5. A sample of O2 with an initial temperature of 50.0C and a volume of 105 L

is cooled to 25C. The new pressure is 105.4 kPa and the new volume is

55.0 L. What was the initial pressure of the sample?

Im lost on these :(...

Few more practice questions I need some help with... Thx for any help

1. Using kinetic theory, explain why a tire is more likely to blow out during a

trip in the summer than during one in the winter.

2. Use kinetic theory to explain why on a cold autumn morning a camper’s air

mattress may appear to be somewhat flatter than when it was blown up the

afternoon before. Assume no leaks.

Some of my practice questions... Could use help on a couple.

1. How does the melting point of water change as the pressure increases?

2. What does the line separating the solid phase from the vapor phase represent?

3. What does the line separating the liquid phase from the vapor phase represent?

4. What is the vapor pressure of liquid water at 100C?

These are the questions i was unsure of

1. How does the crystalline structure of graphite compare with that of diamond?

2. Why is diamond classified as an allotrope of carbon?

3. Peanut brittle is a candy that is poured out while hot onto a surface. It is allowed

to cool and harden into a sheet, which easily breaks into irregularly shaped

pieces. The sugar in peanut brittle solidifies without reforming its crystal lattice.

What type of solid is peanut brittle?

4. Which type of solid is likely to have the lowest melting point—an ionic solid

or a molecular solid? Explain.

5. Give an example of a crystalline solid. What is a crystal?

Need help with a few of these questions

1. In general, how do the intermolecular attractions between particles in a gas

compare with those between particles in a liquid?

2. An open beaker is about half filled with water. How can a dynamic equilibrium

be established between the water and the vapor forming above its surface?

3. Explain how the following description is an analogy for evaporative cooling: If

the fastest runner is removed from a race, the average speed of the remaining

runners will be lower.

4. The normal boiling point of ethanol is 78.5°C. The normal boiling point of water

is 100°C. At 75°C, which liquid, ethanol or water, has the greater vapor pressure?

Explain.
