<h3>
Answer:</h3>
1 Nitrogen atom and 3 Hydrogen atoms
<h3>
Explanation:</h3>
- A molecule is the smallest particle of an element or a compound that has the properties of the element or the compound.
- Molecules of elements are made up of similar atoms while those of compounds are made up of different atoms from different elements.
- Compounds are made up of atoms of different elements.
- For example, NH₃ is made up of one nitrogen atom and three ammonia atoms, water(H₂O) is made up of two hydrogen atoms and one oxygen atom.
The answer is B cotton, since you can grow it.
Answer:
The answer to your question is: 6 grams of hydrogen
Explanation:
Data
3.0 moles of hydrogen
1.5 moles of oxygen
3 moles of water
# of grams of hydrogen required to form 3 moles of water?
Equation
H₂ + 1/2 O₂ ⇒ H₂O
3 mole 1.5 moles 3 moles
Atomic weight of H₂ = 2 g
1 mole ----------------------- 2 g
3 moles --------------------- x
x = 3(2)/1 = 6 grams of hydrogens
Answer:
I guess this is correct.
Explanation:
they do have the correct amount of valence electrons.
Answer:
Percent yield = 87.5%
Explanation:
Given data:
Number of moles of Fe(NO₃)₃ = 2.5 mol
Number of moles of Na₂CO₃ = 3.6 mol
Actual yield of NaNO₃ = 6.3 mol
Percent yield of NaNO₃ = ?
Solution:
Chemical equation:
2Fe(NO₃)₃ + 3Na₂CO₃ → Fe₂(CO₃)₃ + 6NaNO₃
now we will compare the moles of both reactant with NaNO₃.
Fe(NO₃)₃ : NaNO₃
2 : 6
2.5 : 6/2×2.5 = 7.5
Na₂CO₃ : NaNO₃
3 : 6
3.6 : 6/3×3.6 = 7.2
Theoretical yield of NaNO₃ is 7.2 mol.
Percent yield:
Percent yield = actual yield / theoretical yield ×100
Percent yield = 6.3 mol / 7.2mol ×100
Percent yield = 87.5%
