Answer:
<em>250 ml</em>
Explanation: I got it right on the lab.
Answer:
286 kPa
Explanation:
Boyles law states that volume of gas is inversely proportional to pressure o gas for a fixed amount of gas at constant temperature
P1V1 = P2V2
where P1 is pressure and V1 is volume at first instance
P2 is pressure and V2 is volume at the second instance
substituting the values in the equation
229 kPa x 4.0 L = P2 x 3.2 L
P2 = 286.25 kPa
the new pressure is 286 kPa
Answer: The temperature goes up.2.The piston doesn't move in and out.3.Heat flows out.4. Amount of heat evolved is +285 kj/mol
Explanation:
The temperature in the water bath will rise because heat being evolved is absorbed it.Based on principle of constant pressure, the piston doesn't move in and out.Since the reaction is a combination reaction, heat will be evolved.
Answer:
1 mole
Explanation:
Given parameters:
Mass of sulfur = 32.066g
Unknown:
Number of moles of sulfur = ?
Solution:
The number of moles of sulfur can be determined using;
Number of moles =
Molar mass of sulfur = 32g/mol
Number of moles = = 1 mole
