I am currently finishing a fish less cycle and I am trying to determine how to stock my tank. It is a freshwater 20 gallon, with a fluval u2 filter. Temp 80 degrees fahrenheit. I was thinking:

1 bristlenose pleco

2 dwarf gouramis

1 angelfish

8 tetras

Thoughts and suggestions welcome. Thanks in advance!

Cheers!

How is the change detected?

What hormone is released in response?

What action does this hormone take?

How does the body return to homeostasis?

Thanks guys!

a 25 mL portion of .100M Ag+ is added to a solution containing .0010 mol of Cl-. This solution is then titrated with 0.0500M SCN- to the end point. Calculate the volume of SCN- that is required for the titration.

0.500M Chloroacetic acid. pH=1.59 how do I calculate the % dissociation?

What is an example of a material for which the specific heat capacity might be readily available and useful but for which the molar heat capacity would not be readily available?

The ions in the unknown hydrate are SO4 2- and Mg 2+

a)the moles of water in the sample before heating.

b)the moles of anhydrate in the sample heated.

c)the empirical formula of the hydrate.

Which of these hydrates CuSO4, CdCl2, CaCl2 have a vapor pressure of water greater the the partial vapor pressure of water in the atmosphere at room temperature?

So I want to create a website to showcase some of my photography, What would you suggest as a free website designing program?

Also how could I make it so my website is nickhowephoto.com even if that isnt the domain( people type in nickhowephoto.com and it takes them to my webpage even if it is a different domain?

here is some of my work so far:

Express the given quantity in terms of sin x and cos x.

Evaluate cos(11π/12) as cos (π/4 + 2π/3)

The figure shown here shows a rectangle inscribed in an isosceles right triangle whose hypotenuse is 2 units long. Image attached at bottom.

(a) Express the y-coordinate of P in terms of x.

(b) Express the area of the rectangle in terms of x.

I am currently using a Canon Rebel XS and am upgrading to a EOS 40D or 50D, also I already have the sigma 8mm fish-eye and canon 100mm macro. I want a lens for shooting skateboarding and snowboarding as well being a good lens for everyday use. I am looking at something in the Canon L-series lenses. Your help and opinion would be greatly appreciated!

a graph has been provided. comparing the relative power to the wavelength in nanometres. low power is located at several wavelengths but at a wavelength of approximately 590 nanometres the relative power peaks out. Help is greatly appreciated!

From what energy level did an electron fall if it emits a photon of 9.38 X 10^-8 m wave-length when it reaches ground state within a hydrogen atom? The constants are rounded off to 3 sig digs so you may have to carefully evaluate your answer...
