Answer:
64 moles
Explanation:
Let us begin by writing a balanced equation for the reaction. This is illustrated below:
2Na + Cl2 —> 2NaCl
From the equation above,
1 mole of Cl produced 2 moles of NaCl.
Therefore, 32 moles of Cl will produce = 32 x 2 = 64 moles of NaCl.
Therefore, 64 moles of NaCl are produced
Answer:
6.77 · 10²³ molecules H₂O
Explanation:
Step 1: Define
2H₂ (g) + O₂ (g) → 2H₂O (g)
0.562 mol O₂
Step 2: Use Stoichiometry
= 1.124 mol H₂O
= 6.76648 · 10²³ molecules H₂O
Step 3: Simplify
We have 3 sig figs.
6.76648 · 10²³ molecules H₂O ≈ 6.77 · 10²³ molecules H₂O
Answer:
Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
