Since the pressure is constant, you can use the equation V₁/T₁=V₂/T₂ and solve for T₂. (T₂=(T₁/V₁)V₂)
since this is a gas law type question, the temperatures need to be in kelvin therefore you need to convert 15°C to kelvin. 15°C+273=288K. The volume are already in L so they don't have to be converted.
now you just need to plug everything in:
T₂=(288K/99L)x1200L
T₂=3491K
The answer is you need if you have a 99L of gas at 288K, you have to increase the temperature to 3491K to get a volume of 1200L if the pressure remains constant.
I hope this helps. Let me know in the comments if anything is unclear.
Answer:
The answer is cold fronts, wind shear, occluded fronts, and mesocyclones. I got it right on USATESTPREP. What was missing is occluded front. Give me brainliest please if this helped.
Have a wonderful day!
Answer:
B. 288. G
Explanation:
Moles of Al :
Given, Mass of Al = 20.4 g
Molar mass of Al = 26.9815 g/mol
The formula for the calculation of moles is shown below:
Thus,
The reaction between Al and I is shown below as:
2Al + 3I₂ ⇒ 2AlI₃
2 moles of aluminium react with 3 moles of iodine
1 mole of aluminium react with 3/2 moles of iodine
0.7561 moles of aluminium react with (3/2)*0.7561 moles of iodine
Moles of Iodine = 1.13415 moles
Molar mass of NaOH = 253.8089 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of Iodine = 288 g
Answer:
Electromagnetic waves can travel through empty space; mechanical waves can not
Explanation:
The salient differences between electromagnetic waves and mechanical waves is that electromagnetic waves can travel through empty spaces but mechanical waves cannot.
Mechanical waves always requires a material medium for their propagation. No known mechanical waves can pass through an empty vacuum.
Electromagnetic waves on the other hand can pass through vacuum. They do not require a material medium for propagation.
This makes them unlimited in their form and mode of propagation.
