Answer:
Synthesis is the Chemical reaction
The reaction is;
2Na + 2H2O → 2NaOH + H2
Answer:
4.4 × 10^(23) atoms
Explanation:
The reaction is;
2Na + 2H2O → 2NaOH + H2
2 moles of Na produces 1 mole of H2 from the equation reaction.
Thus, since 8.2 L of hydrogen gas at STP are produced. And we know that at STP, 1 mole of a gas will have a volume of 22.4 L, and also, We know according to avogadro's number that, 1 mol = 6.02 × 10^(23) atoms, Thus;
8.2 L of H2 × (1 mole of H2/22.4 L) × (2 mole of Na/1 mole of H2) × (6.02 × 10^(23) atoms/1 mole of Na) = 4.4 × 10^(23) atoms
Answer:The answer is 4 and 5
Explanation:because my ahh guessed
Answer:
<h2>12.1 </h2>
Explanation:
Since the pH has been given, the pOH can be found by using the formula
pH + pOH = 14
pOH = 14 - pH
From the question we have
pOH = 14 - 1.9
We have the final answer as
<h3>12.1</h3>
