i have body dysmorphia and borderline personality disorder, which causes me to have a weird perception of what my face looks like. a lot of the time i look in the mirror and feel good about myself and then look at pictures and feel absolutely disgusting.

i’m an 18 year old female and it’s been like this for years. i thought it would stop after a few years bc of puberty and shiii. 

how can i stop sweating as much? 

is that healthy? i’m an 18 year old female. 195lbs. 

i’m an 18 year old girl and i’m always so turned on. it’s extremely annoying and i’ve been this way for years. 

just curious + looking for some inspo haha. 

i’ve lost a lot of hair and i’m tired of it being so thin. does anyone have any tips?? 

 after struggling with an eating disorder and scalp eczema, i have lost quite a bit of hair. i’m looking for some hair growth tips, as dealing with this has been hard on my self esteem. thanks :)) 

i’ve gained about 70lbs over the span of two years and plan on beginning my weight loss journey to lose it all back. In order for me to achieve the flat stomach and smaller arms i aim for (which is where i carry most fat) i need to be at the weight i use to be.. but i don’t want to be really square shaped and scrawny like i was. can i grow muscle (especially in the legs and booty) while losing weight/in a caloric deficit? 

 sometimes i have these dreams where everything is dark, but i can hear what’s going on in the dream i just can’t see. in the dream i won’t be able to move or talk and they feel so realistic. like i’m almost 100% sure that i’m awake until i notice things start to be a little off. and then when i try to wake myself it takes forever in order to get out of the dream. it’s kind of weird and it always freaks me out.

I have a very square shaped booty, which i am very insecure about. is there any way i can growing my hips or just make my glutes rounder without eating in a big caloric surplus? i gain weight so easily and i’m trying to lose weight at the moment. 

i’ve gained a lots of weight over the past two years and i have so many stretch marks now. when i lose all of the weight will they stay or be gone?

I don’t have a credit card or visa debit card. How can i pay with my regular debit card? is that possible? 

1. Use standard heats of formation, H0f, to calculate the change in enthalpy for each

reaction.

a. C2H4 (g) + 3 O2 (g)2CO2 (g) + 2 H2O (l)

b. C6H6 (l) + 9/2 O2 (g)6CO (g) + 3 H2O (l)

c. Br2 (g)Br2 (l)

d. CaCO3 (s)CaO (s) + CO2 (g)

e. 2NO (g) + O2 (g)2NO2 (g)

f. 2C (s, graphite) + O2 (g)  2CO (g)

g. 2H2O2(l)2H2O(l)+O2 (g)

h. 4NH3 (g) + 5O2 (g)4NO (g) + 6H2O(g)

2. If the heat of formation in the chemical reaction below is −395.7 kJ/mol, how can the equation be rewritten to include the heat term? (Hint: watch the number of moles!)

                     S8 (s) + 12O2 (g) → 8SO3 (g)

2. What energy, in kcal, is needed to change 15.0 g of ice at -10oC to 15.0 g of water at 0 degrees celsius?

3. If 13.4 kJ of energy is added to 1.0 kg of ice at 0CC, how much water is produced? How much ice is left?

4. Using the data below, calculate the amount of energy in kJ required to melt a 16.2 g

aluminum pop can. Assume that the initial temperature of the aluminum is 20oC. Give

your answer to 2 decimal places.

 molar heat of fusion of Al (s) = 10.7 KJ/mol

 melting point of aluminum = 660oC

 heat capacity of Al (s) = 0.900 J/goC

1. place them in order of increasing stability:

NO (g) SO3 (g) NaCO3 (s) H2O (l)

2. Calculate the heat of reaction for N2 (g) + O2 (g)  2NO (g), given the following:

   2P (s) + 5Cl2 (g)  2PCl5 (s) Hrxn = −886 kJ 

1. place them in order of increasing stability:
