Answer:
The answer to your question is V2 = 825.5 ml
Explanation:
Data
Volume 1 = 750 ml
Temperature 1 = 25°C
Volume 2= ?
Temperature 2 = 55°C
Process
Use the Charles' law to solve this problem
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Convert temperature to °K
T1 = 25 + 273 = 298°K
T2 = 55 + 273 = 328°K
-Substitution
V2 = (750 x 328) / 298
-Simplification
V2 = 246000 / 298
-Result
V2 = 825.5 ml
295k=22°c
1050k=777°
total heat needed=
(0.475)(777-22)(specific heat capacity of aluminium)+(0.475)(specific latent heat of aluminium)
A. Since you are starting with equal moles of the two reactants, you can see from the balanced equation that you need 3 moles of H2SO4 for every 2 moles of Al(OH)3. So, H2SO4 is the limiting reactant.
B. 0.420 mol H2SO4 X (1 mol Al2(SO4)3 / 3 mol H2SO4) = 0.140 mol Al2(SO4)3
C. Moles of Al(OH)3 used:
0.420 mol H2SO4 X (2 mol Al(OH)3/3 mol H2SO4)
= 0.280 mol Al(OH)3 used Moles remaining
= 0.420 - 0.280
= 0.140 mol Al(OH)3 remaining.
They are made up of chains of Hydrogen and c) Carbon
Explanation:
Rate is a term used to show how quickly something is occurring with time.
It is often used in just every day measurements.
Examples are speed, power consumption, velocity, cost rate, power, acceleration
- Speed is the rate of change of distance with time. It measured in km/hr or m/s
- Power consumption is measured kwh
- velocity is the rate of change of displacement with time. Measured in m/s or km/hr or mi/s
- cost rate is the amount of substance per measurement. Measured in price per cup or mass
- Power is the rate at which work is done. Measured in J/s or Watt
- Acceleration is the rate of change of velocity with time. Measured in m/s²
