Robert asks…

what is the boiling point of diethyl ether using enthalpy of vapourisation and entropy?

diethyl ether ( C4 H10 O) has an ΔvapH of 28.36 kJ/mol and the phase change from liquid to gas has an ΔS° of 96.6 J/mol/K. what is the normal boiling point of diethyl ether?

weight loss cardiff answers:

At the normal boiling point, the liquid and gas phases of a material are in equilibrium. That means the free energy change for the reaction:

liquid -> gas

is zero.

You should also know that ΔG = ΔH – T*ΔS, so at equilibrium:

T = ΔH/ΔS

In this case, you are given the enthalpy and entropy of vaporization, so:

T_boiling = (28,360 J/mol)/(96.6 J/(mol*K)) = 294 K

John asks…

why is it better to use diethyl ether when performing trimyristin extraction from numeg instead of acetone or?

why is it better to use diethyl ether when performing trimyristin extraction from numeg instead of acetone or ethanol? does it have to do with the solubilities of trim. in each of these solvents? how would you rank trimyristin’s solubility in each of these solvents?

weight loss cardiff answers:

Hmm, i wonder why you’d want to do that?

Seriously though, i’d say it was to do with flammability and possibly toxicity, but that’s just a guess.

George asks…

When you add salicylic acid-naphthalene mixture in a diethyl ether with a saturated aqueous sodium bicarbonate?

When you add salicylic acid-naphthalene mixture in a diethyl ether with a saturated aqueous sodium bicarbonate solution, what kind of gas do they form?

weight loss cardiff answers:

CO2(g) is evolved…

Here’s the balanced equation.

C6H4(OH)-COOH (salicylic acid) + NaHCO3 (sodium bicarbonate) –> C6H4(OH)-COO-Na+ (sodium salicylate) + CO2 (carbon dioxide) + H2O

A wash with aqueous sodium barcarbonate solution is usually done to remove any unreacted acidic reagent (salicylic acid, in this case) from the reaction mixture. As you can see, salicylic acid reacts with sodium bicarb to form sodium salicylate, which is water soluble are therefore goes into the water layer. Meanwhile, the organic layer now only contains naphthalene, which can be recovered by evaporation of the diethyl ether solvent.

Hope this helps!!!

How to lose weight quick and easily?

I’m 14 and I weigh about 150 and I’m 5’7″.
I’m more muscular because I play sports.
I really like this guy and we are like bestfriends but I would like to be more then bestfriends and I think being a little thinner would help him like me more.
I would like to lose just 10 pounds to help out with my confidence.
What should I eat daily and what are some quick exercises to do.
I would like to have lost this weight in less then a month.

weight loss cardiff answers:

Your body is still growing and developing so you really should not cut calories. Try cutting out extra sugar such as soda, chips, candy, etc. Since you play sports you should prob. Still eat carbs before a big game for energy. Drink lots of water, eat frequently so your metabolism is working. Add an extra workout in if you want.

Just please be healthy. If a guy truly likes you for you, he will find you beautiful just the way you are. I promise.

Sharon asks…

I need to know how to lose weight quick b4 summer?

I am 5’10 and I weigh 214 lbs. I gained 14 pounds since september and i really want to look hot in my two peice during spring/summer. What are quick ways to lose weight? and how much will i weight by june if i follow those steps.

weight loss cardiff answers:

There are not quick and easy ways, but you have plenty of time before end of april and may, and I think you can definitely get the bikini body you want by then. You can probably lose 40-50 lbs

To lose fat you need to eat lean meats (chicken, fish, turkey, lean beef) , eggs, low gi fruits (apples, bananas, pineapple, oranges), green veggies (broccoli, celery, green lettuce, spinach), only whole wheat breads (look on the package and see if the first ingredient is whole wheat flour, if it is it should be good unless it has high fructose corn syrup like Mrs Bairds does). Jillian Michaels from biggest loser has a great quote, “before you eat your food ask yourself, does it have a momma or did it come from the ground? If not don’t eat it.” Eat 5 – 6 small meals a day, this will increase your metabolism and help you to not feel so hungry in between meals. It’s all about portion and calorie control regardless of what food you are eating, but remember cleaning up your diet and eating X amount of calories of lean good healthy foods instead of X amount of calories of candy bars (I know you are probably not eating 4 candy bars a day but its just an example) will help you lose it faster. The leaner you are eating the faster you will lose it, and you will get a toned healthy look instead of a skinny jiggly look. You also need to drink at least 8 glasses (8oz) of water a day. Sometimes hunger is mistaken for thirst so if you are hungry drink 8 oz of water and wait 30 minutes, if you are still hungry then eat a light healthy snack. Water also helps you feel fuller longer and helps flush out toxins that may prevent fat loss. Also allow your self a cheat day (but don’t go over board and eat everything in sight or like 5 cakes in that day). Allowing yourself a cheat day once a week will help cut out cravings… Think of it like a reward if you did well with your diet and exercise that week have a piece of pie… If not just stick with you healthy food. You can find recipes for decent tasting healthy foods on sights like bodyforlife.com and bodybuilding.com and also on recipe sights like allrecipes.com, foodfit.com, cookinglight.com and foodnetwork.com

You need to do a good mix of both cardio and strength training. Toning and building muscle strength will help you lose fat quicker as you will be burning calories all day to feed your muscle tone instead of just while you doing cardio activity and it increases metabolism. Running, walking, rollerblading, swimming are good cardio work outs. You can also get some at home videos. I personally like Gilad’s Kick boxing, Cathe Friedrich, ten minute solutions videos (ten minute solutions are good because they have 5 ten minute segments and you can do one or all five or three or what ever you want to do at the time and they have a variety, like dance, pilates, yoga, etc.). Also if you get cable/satellite, find the Fittv channel and scroll through the guide and see if anything sounds interesting and do it or record it if it doesn’t fit into your schedule at the time the program comes on. Get your self some 5 pound dumbbells or a gym member ship and do bicep curls, push ups, sit ups, squats, dead lifts, lunges, tricep over head extensions, chest presses, shoulder presses, etc. You can do most of this on your own if you just go and buy some free weights, but a gym membership is helpful as well. If you do end up getting a gym membership I would consult a personal trainer (most memberships come with a free session) they can show you what to do and come up with a meal plan for you… You can find the videos I mentioned on the web at collagevideo.com, or at ross (cheap cheap at ross) or walmart or any other place that sells dvds.

Lastly, don’t get discouraged, it takes time (it didn’t didn’t get there over night, its not coming off over night)… You should be losing 2 pounds of fat a week safely, more is not typically safe. But you could gain weight especially if you are gaining muscle. So if you get on the scale and it says you’ve gain two pounds don’t freak out… Just look in the mirror and go by how your clothes look and feel on you. Hope this helps! Email me if you have any other questions!

*DISCLAIMER* one thing doesn’t work for everyone, some people need different things. So if it doesn’t work change your diet or make you work outs more intense… This is just a generic answer of how you should change your lifestyle to be healthy. Yes you will see it in multiple answers because who in their right mind would want to right all this info out and change it up a bit every time (it doesn’t really need to be changed) It’s a sample of what works for many people. This is not spam, I am not trying to sell you anything, yes there are websites listed on here but that is simply because I can’t post every healthy recipe or work out regime in the world. I am always open for questions, just email me if you have any and I’ll do my best to answer you.
