At stp,250cm3 of gas had a mass of 0.36g.what result does this give for the molar mass of the gas
Answer:
32,256g/mol
Explanation:
n= V/Vm
n = 0.25/22.4
n = 0.01
0.01 = 0.36/M
M = 0.36/0.01

do all types of energy have the same amount of energy
Answer:
Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth.
Explanation:
Answer:No, for example electricity doesn't work like physical energy

Lithium, Hydrogen, Sodium, or Oxygen, Sulfur, Selenium They are all in the same column. Find three elements in the same family and list them. 4. Oxygen, Carbon, Nitrogen, Aluminum, Silicon, Phosphorous They are all in the same row
Explanation:
The volume (V) of an enclosed mass of gas is 350kPa. The pressure of the endlosed gas is now decreased to 125kPa, at constant temperature. What will the new volume of the gas be, in terms of V (2)
Answer: V1/V2 = 0.357,
V2 = (V1/0.357) or 28.0*V2
Explanation: Use the combined gas law: P1V1/T1 = P2V2/T2 We want to find V1/2 (or V2/V1). Rearrange:
V1/V2 = (P2/P1)(T1/T2)
The units all cancel. Temerature is constant, so (T1/T2) = 1.
V1/V2 = (125/350)*(1)
V1/V2 = 0.357
What are the two key ingredeints that help science move forward?
Answer:
science needs both ideas the hypothesis and facts the quantitative results to move forward
Explanation:
the two primary features of a scientific hypothesis are falsifiability and testability which are reflected in an If…then statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation
The process by which any metal is extracted from its ore is
A)reduction
B)electrolysis
C)displacement
D)decomposition
Answer:
D displacement
Explanation:
This is because removing metal means your displacing it
When a metal such as copper is heated,it expands. Can anyone tell me what happens to the metal particles as the solid metal expands?
Answer:
The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.
Explanation:
As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.
Hope this helps, let me know if any more clarification is needed.

scientist to modify
or revise a
hypothesis
Answer:
Upon analysis of the results, a hypothesis can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.
