Answer:
7.86 moles of sodium chloride are produced.
Explanation:
Given data:
Moles of chlorine = 3.93 mol
Amount of sodium = excess
Moles of sodium chloride formed = ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Now we will compare the moles of sodium chloride with chlorine.
Cl₂ : NaCl
1 : 2
3.93 : 2×3.93 = 7.86
Chlorine is limiting reactant that's why we compare the NaCl with only number of mole of chlorine.
Thus, 7.86 moles of sodium chloride are produced.
VSEPR is an acronym which stands for Valence Shell Electron Pair Repulsion. The theory is most commonly used as basis for establishing the shapes of the substances.
CF4, as can be seen, has only one carbon atom and four fluorine atoms. The most preferred shape of the chemical is therefore, tetrahedral.
Answer: Energy released during the reaction is 0,299 kcal
Explanation: ΔH is the amount of energy released when 1 mol of C3H8 reacts, but there is no 1 mol but less, 3.40 x 10^20 molecules
Using Avogadro's number is possible to calculate the number of moles
The product of the mol number and ΔH is the energy released during the reaction
Sedimentary rocks are formed in D. ancient seas because they are formed when layers of sediment (sand, mud, dead organisms, etc) builds up on top of each other and pressure compresses them into rock
