Answer:
Sodium sulfite (Na2SO3)
Explanation:
Sulfuric acid is able to displace volatile acids from their corresponding salts and the acids displaced are unstable and they break down to give volatile products
For example, in to reaction of sulfuric acid and sodium sulfite; two processes occur
1. Sulfuric acid forms sodium sulfate and sulfurous acid
Na2SO3(s) + H2SO4(aq) -------> Na2SO4(aq) + H2SO3
2. The H2SO3 is unstable thereby decompose spontaneously to water and sulfur dioxide gas.
H2SO3 -----------> H2O(l) + SO2(g)
Final reaction gives;
Na2SO3(s) + H2SO4 (aq) ---------> Na2SO4(aq) + H2O(l) + SO2(g)
The temperature for the reaction is calculated as follows
delta H/ delta S
delta H=-70 Kj
delta S =-0.300 kj/k
temperature is therefore = -70kj/-0.300kj/k =233.33 K
Answer:
Mercury, Earth, Saturn, Jupiter, and the sun
Explanation:
this is from smallest to largest. hope it helps
How much of a product is made depends on the limiting reagent. there are different ways to determine the limiting reagent and this depends on the professor way of teaching it. I will use the must common one. so keep in mind that the way to solve this problem may vary.
first we convert each grams to moles using the molar mass of the molecules. then convert moles to moles of asked molecule (H2O) using the mole-mole ration, and moles of water to grams using the molar mass of water.
molar mass of Na= 23.0 g/mol
molar mass of H₂O= 18.0 g/mol
ratios (based on the balanced equation coefficients)
2 mol Na= 1 mol H₂
2 mol H₂O= 1 mol H₂
calculations:
since H₂O gives less of the product than the other one. H₂O is the limiting reagent and the answer is
4.49 g
