The solubility of silver carbonate, Ag2CO3, in pure water is 1.27 × 10–4 moles per litre. Calculate the value of Ksp for silver carbonate from these data.

Hi, stuck on a few questions

Compared to a frog, what would you predict about the circulatory, respiratory and excretory systems of a bird or mammal

What would you predict the food intake per gram of body tissue of a bird or mammal would be compared with a frog

thanks in advance :D

Given the data:

NH3(g), Δf Ho = -46.0 kJ mol–1, So = +192.5 J mol–1 K–1

NO(g), Δf Ho = +90.4 kJ mol–1, So = +210.6 J mol–1 K–1

H2O(l), Δf Ho = -286 kJ mol–1, So = +69.96 J mol–1 K–1

O2(g), Δf Ho = 0.00 kJ mol–1, So = +205 J mol–1 K–1

calculate the standard free energy change, ΔGo, for the reaction:

2 NH3(g) + 5/2 O2(g) → 2 NO(g) + 3 H2O(l)

Select one:

a. –100.8 kJ mol–1

b. –206.7 kJ mol–1

c. –276.5 kJ mol–1

d. –505.8 kJ mol–1

I keep getting a value that is not any of the multiple choice, and i've checked my calculations over 3 times. HELP

Use the data below to calculate ΔG° in kJ for the potential atmospheric ozone-depleting gas reaction

CO(g) + O3(g) → CO2(g) + O2(g)

in which 40.3 g of carbon monoxide gas reacts with ozone under standard conditions.

Enter your answer for ΔG° in the "Answer" box.

Standard Free Energy of Formation Values (ΔGf0), kJ/mol at 298K

CO2 -394.4

CO -137.3

O3 163.4

I'm stuck on this question and unsure how to do it

Hi can you help me fill in the blanks, its related to research methods:

If the results of an experiment are stable and consistent, they they can be considered _____________ , whereas, if the results are accurate then they can be considered ______________________

Hi, I was wondering if someone can explain to me why principle 2 and 7 are "green"

hi i need help with a question ):

Show that the point P (-2,0) lies on the line joining A (7,-3) and B (-5,1) and find the ratio in which it divides the line AB

how do you find the value of a & h

if a cubic function has a rule f( x) = a(x-h)^3 +3

and it passes through 4, 3 and 5 , 4

hi, i want to access the tiffany pictures on thestephi.com

but sadly you have to be korean and a member to join and i was hoping if anyone had an account they could lend me so i can see the pictures thank you (:

Im into T-ara now since they released "Yayaya" & " Why Are You Being Like This" but i still dont know all the members could you please help me?
