Answer:
Moles of NaCl formed is 6.0 moles
Explanation:
We are given the equation;
2 Na(s) + Cl₂(g) → 2 NaCl(s)
- Moles of Na is 6.0 moles
- Moles of Cl₂ is 4.0 moles
From the reaction;
2 moles of sodium reacts with 1 mole of chlorine gas to form 2 moles of NaCl
In this case;
6 moles of Na would require 3 moles of Cl₂, this means that chlorine gas is in excess.
Thus, the rate limiting reagent is sodium.
But, 2 moles of sodium reacts to form 2 moles of NaCl
Therefore;
Moles of NaCl = Moles of Na
= 6.0 moles
Thus, moles of sodium chloride produced is 6.0 moles
Answer:
a lack of genetic variety
first one is the correct one
Answer:
2Al (s) + 6HCl (aq) → 2 AlCl3 (aq) + 3H2 (g)↑
Explanation:
- We can put an up arrow to H2 cause as it is a gas, it can be released to the atmosphere.
- Aluminum as metal must be solid.
- As we have two solutions, both are aqueous phase.
- The stoichiometry must match on both sides of the reaction to have the same amount of elements of each compound.}
Reactants : 2 Aluminun
6 Hydrogen
6 Chloride
Products:
2 Aluminun
2.3 = 6 Chloride
3.2 = 6 Hydrogen
Answer:
SI unit of force
Explanation:
Newton(N) is the Standard International unit used to measure force. This was named after Sir Isaac Newton.
