Group 18 is known as the Noble/ Inert Gases
Answer:
5.38 moles of CO₂ are produced
Explanation:
This is the reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
First of all, let's convert the mass of C₃H₈ to moles (mass / molar mass)
79 g / 44 g/mol = 1.79 moles
So ratio is 1:3.
1 mol of C₃H₈ is needed to produce 3 moles of CO₂
1.79 moles of C₃H₈ would produce (1.79 .3) /1 = 5.38 moles
Answer:
Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution. A concentrated solution of sodium oxide in water will have pH 14. ... For example, it reacts with dilute hydrochloric acid to produce sodium chloride solution.
Answer:
See explanation.
Explanation:
Hello there!
In this case, according to the described chemical reaction, we first write the corresponding equation to obtain:
Thus, we proceed as follows:
Part 1 of 3: here, since the molar mass of silver and copper (II) nitrate are 107.87 and 187.55 g/mol respectively, and the mole ratio of the former to the latter is 2:1, we can set up the following stoichiometric expression:
Part 2 of 3: here, the molar mass of copper is 63.55 g/mol and the mole ratio of silver to copper is 2:1, the mass of the former that was used to start the reaction was:
Part 3 of 3: here, the molar mass of silver nitrate is 169.87 g/mol and their mole ratio 2:2, thus, the mass of initial silver nitrate is:
