Answer:

1. Protons

2.Neil Bohr model

3.shell

4.results and conclusion for gold foil experiment

   The protons are not scattered uniformly but they are concentrated at the nucleus (core)  of the atom

 The nucleus is largely responsible for the entire mass of the atom.

There is an empty space surrounding the nucleus and the electrons revolve round an orbit at a distance from the nucleus

What is the maximum amount of ammonia that can be produced when 0.35 mol Nz reacts with 0.90 mol Hz?
professor190 [17]

Answer:

0.6 moles NH₃

Explanation:

The reaction that takes place is:

  • N₂ + 3H₂ → 2NH₃

First we <u>determine the limiting reactant</u>:

  • 0.35 mol N₂ would react completely with (3*0.35) 1.05 moles of H₂. There are not as many H₂ moles, so H₂ is the limiting reactant.

Then we <u>convert H₂ moles (the limiting reactant) to NH₃ moles</u>, keeping in mind the <em>stoichiometry of the reaction</em>:

  • 0.90 mol H₂ * \frac{2molNH_3}{3molH_2}= 0.6 moles NH₃

Find the volume of 56.0 grams of O2 at stp
BaLLatris [955]
The molar mass of O2 is 32g/mol. So the mol amount of these O2 is 56/32=2 mol. STP stands for the standard temperature and pressure which means the temperature is 0 ℃ and pressure is 100 kPa. And the molar volume of gas is 22.7 L/mol under STP. So the answer is 22.7*2=45.4 L

Write a chemical equation for nh4+(aq) showing how it is an acid or a base according to the arrhenius definition.
GuDViN [60]

An Arrhenius acid by definition dissociates in water to form H3O+ (or H+) ions while an arrhenius base dissociates in water to form OH- ions.

NH4+(aq) can be categorised as an arrhenius acid since it releases H3O+ ions in aqueous media

NH4+(aq) + H2O (aq) ↔ NH3 (aq) + H3O+(aq)
