87.07 torr
Explanation:
n:7.7059 g-5.9203 g= 1.7856 g
Molar mass of benzene = 78.11g/mol
n=1.7856 g /78.11g/mol= 0.023 mol
T= 273 + 28 = 301 K
PV=nRT.
Weget
P=nRT/V
P=(0.023 mol x 8.3 J/molK x 301 K) / 0.00495m3= 11608. 3Pa= 87. 07 Torr
Answer: 87. 07 Torr
When food burns, energy is lost.
When food is consumed by the body, it is broken down into simple sugars, carbohydrates, and fats. (Energy gained)
Answer:
The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down.
I believe it would be C. While D is also a good answer, the question asks for the statement that is most likely true, and there is no absolute guarantee that in 20 years our resource use will be higher than it is now.
