Chemistry
Sir, thank you for answering. I thought it was the adding the Cl2, but it was wrong. That is why I went with decreasing the temp, but now knowing that it is wrong as well. I think my only option is the addition of PCl5 (which I meant to put at the top vice Pcl4) I hope I am on...
Chemistry
Consider the following equilibrium: PCl3 (g) + Cl2 (g) yields PCl5 (g) delta H= -92KJ The concentration of PCl3 at equilibrium may be increased by: decreasing the temp (think this is it) adding Cl2 to the system the addition of neon the additio of PCl4

Calculate the molecular weight of a small protein if a 0.32 g sample dissolved in 161 mL of H2O has an osmotic pressure of 9.0 mmHg at 25 degree celcius. (R=0.0821 L X atm/K X mol)
Physics
Our Milky Way galaxy is very similar to our neighboring galaxy Andromeda. Consider that each galaxy contains approximately 4.0 x 10^11 stars each star having an average mass of 2.0 x 10^30 kg. a. If the gravitational pull of Andromeda is 2.4 x 10^30 N, how far away is Andromed...

math sequence
the first 5 terms of a linear sequence are given below: 8,6,4,2,0... What is the 100th term in the sequence? A. -192 B. -190 C. -108 D. -90 I could figure this out in like 5 minutes, but I know there's a pattern I can't remember to figure it out quicker.
algebra
4y + 5x = -7 divide everything by 4 to get y alone 4y/4 + 5x/4 = -7/4 y + 5x/4 = -7/4 subtract 5x/4 from both sides of equation y +5x/4 = -7/4 -5x/4 -5x-4 ________________ y = -5x -7 / 4 -5x - 7 ___________ 4
