Pressure in the submarine when the temperature is changed to 293 K is 108.9 K Pa
Explanation:
Pressure in the submarine = 108.9 kPa
Volume, V = 2.4 * 10^5 L
Pressure, P = 116k Pa
Temperature, T = 312 K
Ideal gas law: PV = nRT or n = PV / RT
So, moles of gas, n =116 KPa * 2.4 * 10 ^5L / 8.314 LK Pa K^-1 *312 K
= 1.073 *10^4 mol
when temperature is changed to 293K,
PV = nRT or P = nRT / V
=1.073 *10^4 mol *8.314 LK Pa mol^-1 K^-1 *293 K / 2.4*10^5L
=108.9 K Pa
Pressure in the submarine when the temperature is changed to 293 K is 108.9 K Pa
I know it's only 5 points but heres the answer
<span>1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.
2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.
3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.
4. No, because the sugar would dissolve.
5. No, on this case the displacement method would not work because of the weight difference
I hope this helps you a bit.</span>
It would be a chemical change.
Hope this helps!
Answer:
Volume = 0.2 L
Explanation:
Given data:
Number of moles of NH₄NO₃ = 1.2 mol
Molarity of solution = 6 M
Volume of solution = ?
Solution:
Formula:
Molarity = number of moles / volume of solution
by putting values,
6 M = 1.2 mol / Volume
Volume = 1.2 mol / 6 mol/L
Volume = 0.2 L
Answer: 12
Explanation: 18mL 14L(1.6x10-2) 23ml 12L
1 Milliliter (mL) is equal to 0.001 liter (L)
1.6x10-2= 14 you see my point?
18 and 23 are both mL so bye bye 14 bigger then 12 so there
