Answer: My guess would be condensation.
Explanation: Condensation makes water into water droplets.
Answer:
D?
Explanation:
I think D hmm is the answer if I am wrong pls anyone or someone type the right answer but for me is d
Answer:
Kindly check the explanation section.
Explanation:
From the description given in the question above, that is '' H subscript f to the power of degree of the reaction" we have that the description matches what is known as the heat of formation of the reaction, ∆fH° where the 'f' is a subscript.
In order to determine the heat of formation of any of the species in the reaction, the heat of formation of the other species must be known and the value for the heat of reaction, ∆H(rxn) must also be known. Thus, heat of formation can be calculated by using the formula below;
∆H(rxn) = ∆fH°( products) - ∆fH°(reactants).
That is the heat of formation of products minus the heat of formation of the reaction g specie(s).
Say heat of formation for the species is known as N(g) = 472.435kj/mol, O(g) = 0kj/mol and NO = unknown, ∆H°(rxn) = −382.185 kj/mol.
−382.185 = x - 472.435kj/mol = 90.25 kJ/mol
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>
The correct answer is both newlands and mendeleev arranged elements according to their atomic masses, but only mendeleev used chemical properties as well.
The explanation:
1- Newlands arranged all the elements known at the time into a table in order of relative atomic mass. ... He then put the similar elements into vertical columns, known as groups.
2- Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
He realised that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table.
