Answer:
Atoms are the building blocks of cells, which are the building blocks of all things. Every thing that exists is comprised of cells of various elements and compounds, held together by atomic bonds.

Answer:
N₂ is the limiting reactant
Explanation:
The balanced reaction between N₂ gas and H₂ gas is:
N₂ + 3H₂ → 2NH₃
In order to determine the limiting reactant, we have to <u>calculate the number of moles of each rectant</u>, using their molecular weight:
- Moles of N₂= 100 kg *
= 3.57 kmol - Moles of H₂= 100 kg *
= 50.0 kmol
Lastly, we multiply the number of moles of N₂ by 3, and the number of moles of H₂ by 1; due to the coefficients in the balanced reaction. Whichever number is lower, belongs to the limiting reactant.
N₂ => 10.7
H₂ => 50.0
Thus N₂ is the limiting reactant
1 kg =1000 g = 10³ g,
1 m = 100 cm ,
(1m)³ = (100 cm)³= (10²)³ cm³ = 10⁶ cm³ or 10⁶ mL
5,427 kg/m³ = <span>5,427 kg/ 1m³ = (5427 * 10³ g)/ 10⁶ mL=5427/10³ g/mL=
=5427/1000 g/mL = 5.427 g/mL
</span>5.427 g/mL is density of Mercury, and 1.0 g/mL is density of water.
Density of Mercury is more then density of the water, so
mercury will sink in the water.
Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.
