He arranged them in groups of elements and made sure he put similar properties next to each other in vertical columns
H₂ will have the highest average kinetic energy
<h3>Further explanation </h3>
Energy because this motion is expressed as Kinetic energy (KE) which can be formulated as:
Average velocities of gases can be expressed as root-mean-square averages. (V rms)
R = gas constant, T = temperature, Mm = molar mass of the gas particles
From the two equations above, it can be concluded
- KE is directly proportional to gas velocity
- Gas velocity is inversely proportional to molar mass
So <em>the highest KE is owned by the gas with the smallest molar mass</em>
<em />
Molar mass of the gas :
A) H₂ : 2 g/mol
B) N₂ : 28 g/mol
C) O₂ : 32 g/mol
D) F₂ : 38 g/mol
So <em> H₂ has the highest average kinetic energy</em>
Answer:
Zinc metal reacts with hydrochloric acid according to the following balanced equation:
Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
When 0.122 gg of Zn(s)Zn(s) is combined with enough HClHCl to make 50.9 mLmL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.5 ∘C∘C to 24.2 ∘C∘C.
