Answer: At temperature of 269 K the gas would occupy 1.33 L at 217 kPa
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 147 kPa
= final pressure of gas = 217 kPa
= initial volume of gas = 1.8 L
= final volume of gas = 1.33 L
= initial temperature of gas = 
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Thus at 269 K temperature the gas would occupy 1.33 L at 217 kPa
Answer:
Option B
Explanation:
Remember that the products are on the right side of a chemical equation while the reactant is on the left.
In this case we have...
C2H6 + O2 ⇒ CO2 + H2O
Since C2H6 and O2 are on the left side that would mean they're the reactants, while CO2 + H2O are the products. Which means your answer is option B or "C2H6 + O2 are the reactants, CO2 + H2O are the products."

Answer:
Erosion by water
Explanation:
Moving water carrying away small pieces of rock is erosion by water.
E.g when the sea hits on the cliff and then takes away the fragments with it

Answer:
HCI (aq) + NaOH (aq) --> H2O (l) + NaCl (aq)
Explanation:
A double displacement reaction is a type of reaction where two reactants exchange ions to form two new compounds. Here we can see that both the acid and the base exchanged an ion each to for salt and water, 2 new products.
Answer: ✅
The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure.
