Answer: The new volume of the gas is smaller.
Explanation:
Volume and pressure are inversely proportional (as one goes up, one goes down). So as you increase the pressure, you decrease the volume.
Answer:
The new temperature is 373 K
Explanation:
Step 1: Data given
Volume air = 5000 mL = 5.0 L
Temperature = 223K
New volume = 8.36 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒V1 = the initial volume = 5.0 L
⇒T1 = the initial temperature = 223 K
⇒V2 = the new volume = 8.36 L
⇒T2 = the new temperature
5.0/223 = 8.36 /T2
T2 = 373 K
The new temperature is 373 K
Answer:
2.103 J/C
Explanation:
Quantity of heat = Heat Capacity * Temperature change
Heat Capacity = Quantity of heat / Temperature Change
Heat Capacity = 61/29
Heat Capacity = 2.103 J/C
Answer:
2.86g
Explanation:
Mass of HCl = 2.87g
Mass of water = 3.75g
Mass of NaCl = 1.98g
Unknown:
Mass of NaOH reacted = ?
Solution:
The reaction expression is given as:
HCl + NaOH → NaCl + H₂O
According to the law of conservation of mass, the mass of reactants and products must be the same.
Mass of HCl + Mass of NaOH = Mass of NaCl + Mass of H₂O
2.87g + Mass of NaOH = 1.98g + 3.75g
Mass of NaOH = 1.98g + 3.75g - 2.87g = 2.86g
