Answer:
160 g of NaOH
Explanation:
Reaction: 2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O
When a base and an acid react, the produce water and a salt. → Neutralization
In this reaction 2 moles of hydroxide need 1 mol of sulfuric acid to react, it is the same to say that 1 mol of sulfuric acid needs 2 moles of NaOH to react. We convert the mass of sulfuric to moles and we propose the rule of three:
196 g / 98 g/mol = 2 moles
1 mol of sulfuric acid needs 2 moles of NaOH to react
Then 2 moles of sulfuric acid will react with (2 . 2) /1 = 4 moles of NaOH
We convert the moles of base to grams → 4 mol . 40 g /1mol = 160 g
it can form 3 bonds because 1 electron is in each of the 3 2p oribitals.
The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1
so specifically the 2p oribital is :
2px1 2py1 2pz1
Evaporating? But that’s with a boiling liquid
Answer:
0.6 moles NH₃
Explanation:
The reaction that takes place is:
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 *
= 0.6 moles NH₃
Matter is a slightly archaic word for something with mass, as in the conservation of matter (which must be paired with the conservation of energy to still hold true. Mass can be converted back and forth between energy, so therefore so can matter. Of course relativistic mass is conserved as it's a function of the energy of an object in that reference frame.
