Answer:
6.57 L
Explanation:
First, calculate the <em>moles of hydrogen</em> produced, then use the Ideal Gas Law to calculate the <em>volume of hydrogen</em>.
Step 1. Write the <em>chemical equation</em>.
: 22.99
2Na + H₂O ⟶ 2NaOH + H₂
Step 1. Convert <em>grams of Na</em> to <em>moles of Na</em>
Step 2. Use the molar ratio of H₂:Na to convert <em>moles of Na</em> to <em>moles of H₂</em>.
Step 3. Use the Ideal Gas Law to calculate the <em>volume of hydrogen</em>.
<em>pV = nRT</em>
Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)
In order to find the mass of tin with the given volume of 5.5 L and density of 7.265, we will use the formula
Density = Mass / Volume
We will just multiply both sides of the equation by the volume and we will get:
Mass = Volume x Density
We can now solve the problem by substituting the given.
Mass = 5.5 L x 7.265 g/L
Mass = 39.96 g
Answer: there are 39.96 grams of tin
Answer:
sulfur oxides and nitrogen oxides
