Answer:
Model 2 and model 3
Explanation:
Both atomic models represent hydrogen, which consists of one proton in the nucleus. Both atomic models consists of 1 proton, which means that both their atomic numbers are equal to 1
Answer:
The all 4 the given statements are part of Dalton's atomic theory.
Explanation:
Dalton's postulates or Dalton's atomic theory:
- Matter is made up of small particles termed as atom.
- Atoms are indivisible particle.
- Atoms of different element have different masses and properties.
- Atoms of the same element have the identical size, mass, and structure.
- During chemical reaction, rearrangement of atoms takes place.
- Atoms of different different combines together to form new compounds in simple whole number ratio.
Answer:
The mass of the atom will change
Explanation:
The mass of the atom will alter if the changing the amount of electrons in an atom charge would result in being positively or negatively charged (Correct me if I'm incorrect sorry If I got this wrong)
The volume of NH₃ produced at STP : 0.237 L
<h3>Further explanation</h3>
Reaction
N₂ + 3H₂ → 2NH₃
1 mol = 6.02 x 10²³ particles
9.6 X 10²¹ molecules of Hydrogen, mol :
mol H₂ : mol NH₃ = 3 : 2
mol NH₃ :
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). <em>At STP, Vm is 22.4 liters/mol.</em>
The volume of NH₃ :
