Answer:
A.) Polymers are substances that have relatively large molecules
Solids— have tightly packed molecules, structured shape
Liquid— have no definite shape and the molecules are not tightly packed like a solid, they are a lot more loose.
Gas— No structure at all, molecules are free flowing
Sorry I couldn’t be a better help.. but I hope this gives you a bit of an idea :)
The answer is:
the molarity = 50 moles/liters
The explanation:
when the molarity is = the number of moles / volume per liters.
and when the number of moles =2.5 moles
and the volume per liters = 0.05 L
so by substitution:
the molarity = 2.5moles/0.05L
= 50 moles /L
MARK ME BRAINLIEST PLEASE!!!!!!!!!
The correct answer is the gamma ray. It has the most penetration power and will pass through a number of things. Also, a gamma ray has shorter wavelength therefore higher energy from the equation, Energy = hc/wavelength.
First, make sure to balance your equation.
3H2(g) + N2(g) ⇄ 2NH3(g)
Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.
Kc = [NH3]^2 / [H2]^3[N2]
