What is the energy of green light with a wavelength of 5.50x10^-7m?

Chemistry
Um. that does not answer my question of whether liquids, aqueous, and gases appear in Kc expressions or not.

Chemistry
And this one too! I thought it should also have a Kc expression but my notes only mentioned the Kp expression: ( that weird arrow is the forward backward arrow for a reversible reaction) H2(g) + Br2(l) --><-- 2HBr2(g) Kc = [HBr]^2 / [Br][H2] Please tell me if im right! I...

Chemistry
I'm doing chemical equilibrium, and there's a question in my lecture notes. Can someone check my answers and tell me if i'm right or wrong? Thanks! The Kc expression for this reversible reaction: 3Fe(s) + 4H2O (g) --><-- Fe3O4(s) + 4H2 (g) is [H2]^4 / [H2O]^4...

Chemistry
Does "gaseous reactions" mean that all the products and reactants in a chemical equation are all in gaseous state?

What is the percentage of land used by farmers compared to farming land avalible in Hawaii? Thanks!

Describe the end behavior of the graph of the polynomial function by completing these statements: f(x)→? as x→-∞ and f(x)→? as x→+∞. 1. f(x)=-(x^2)+1 2. f(x)==10x^3

Math
A man left his property to his wife, his son, his daughter, and his sister. His son and daughter got half of the property, sharing in the ratio of 4 to 3. His wife got twice as much as the daughter. If his sister received \$15,000, what was the value of all of his property?

physics
so how do i answer this? :) pls. and thank you

physics
A 0.25 kg skeet (clay target) is fired at an angle of 30 degrees to the horizon with a speed of 25 m/s. When it reaches the maximum height, it is hit from below by a 15 g pellet travelling upward at a speed of 200 m/s. The pellet is embedded in the skeet. (a) How much higher d...
