Answer:
5528 balloons
Explanation:
Explanation:
At constant pressure and number of moles, using Boyle's law
Given ,
V₁ = 155.0 L
V₂ = ?
P₁ = 1835 psi
P₂ = 1 atm = 14.7 psia
Using above equation as:
Volume of each balloon = 3.5 L
Thus, number of balloons,
Answer:
Formation of a precipitate
Explanation:
- A precipitate is a compound in solid-state that is formed when two soluble or aqueous compounds or salts react during a precipitation reaction.
- Precipitation reaction involves a reaction between two soluble salts or compounds to form a precipitate and an aqueous compound.
- For instance, a reaction between potassium chloride and silver nitrate is a precipitation reaction.
KCl(aq) + AgNO₃(aq) → KNO₃(aq) + AgCl(s)
- All the other choices are indicators of a chemical reaction or a chemical change.
Answer:
0.189
Explanation:
Aqueous solution only has ammonia and water in it. Assume total mass of 100 g
Meaning mass of ammonia is 18% of 100 g = 18 g
Mass of water is 82% of 100 g = 82g
Number of moles of ammonia = mass / molar mass ammonia =18/17 = 1.059
Number of moles of water = mass / molar mass water = 82/18 =4.556
Mole fraction ammonia = 1.059 / (1.059+4.556) = 0.189
