Answer:
1.An initial observation is the measurement that you take before you start any process that might cause a change. When you compare your subsequent observations with the initial one, you will see whether any change has taken place, and you will be able to measure the change.

The Kinetic Molecular Theory has 5 main tenets, and they basically explain that the gas molecules are in constant motion. It is random and it causes constant collisions between the particles and also with the container's walls.
So, the answer is B. Kinetic Molecular Theory.
Answer: Geothermal resources are reservoirs of hot water that exist at varying temperatures and depths below the Earth's surface. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including electricity generation, direct use, and heating and cooling. In the United States, most geothermal reservoirs are located in the western states.
Renewable—Through proper reservoir management, the rate of energy extraction can be balanced with a reservoir's natural heat recharge rate.
Baseload—Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions.
Domestic—U.S. geothermal resources can be harnessed for power production without importing fuel.
Answer:
68 g
Explanation:
Molar mass (C10H16) = 10*12.0 g/mol + 16*1.0 g/mol = (120+16)g/mol =
= 136 g/mol
m (C10H16) = n(C10H16)*M(C10H16) = 0.5 mol*136 g/mol = 68 g
n(C10H16) - number of moles of C10H16
M(C10H16) - molar mass of C10H16
Answer:
The volume will be 18,23 ml.
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin: 0 ° C = 273K, 44+273=317K, 17+273=290 K. The volume in L= 22/1000= 0,022L
P1xV1/T1= P2xV2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((0,905 atm x 0,022L/317K)x 290K)/0,999atm= 0,01823 L
0,01823x 1000= 18, 23 ml
