Dalton based in his theory proposed the elements that are composed of identical mass and properties
Answer:
300 kPa
Explanation:
P2=P1V1/V2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
Answer:
c. ceramic
Explanation:
because b d and a are metals c is not
The rolling magma causes uneven currents in underneath the earths crust. Sort of similar to wind patterns in the sky but think of them as underground and in a much thicker fluid. Ocean currents might be a better analogy. Because of it being a much more viscous fluid, there is greater pressure buildup which can cause torsion, compression, expansion etc. when you bake a cake look how the dough underneath expands & the top crust cracks and stretches. Hope that helps.
Given data:
Hydrogen (H) = 3.730 % by mass
Carbon (C) = 44.44%
Nitrogen (N) = 51.83 %
This means that if the sample weighs 100 g then:
Mass of H = 3.730 g
Mass of C = 44.44 g
Mass of N = 51.83 g
Now, calculate the # moles of each element:
# moles of H = 3.730 g/ 1 g.mole-1 = 3.730 moles
# moles of C = 44.44/12 = 3.703 moles
# moles of N = 51.83/14 = 3.702 moles
Divide by the lowest # moles:
H = 3.730/3.702 = 1
C = 3.703/3.702 = 1
N = 3.702/3.702 = 1
Empirical Formula = HCN
