The following are considered to be a homogeneous mixture: vinegar, sugar water and soda pop in a sealed bottle.
When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law,
PV=nRT we can say that with everything constant, volume must also be constant.
The answer is (2) 2 L of methane gas.
I would say d but I’m not sure
The required pressure of the gas is 546 mmHg.
<h3>What is the relation between volume and pressure?</h3>
Relation between the volume and pressure of gas is explained through the ideal gas equation PV = nRT, and for the question required equation is:
P₁V₁ = P₂V₂, where
P₁ & V₁ are the initial pressure and volume.
P₂ & V₂ are the final pressure and volume.
On putting values from the question to the equation, we get
P₂ = (780)(350) / (500) =
P₂ = 546 mmHg
Hence required pressure is 546 mmHg.

Answer: caffeine is a compound.
Explanation:
1) As stated c<span>affeine contains hydrogen, carbon, nitrogen, and oxygen atoms in a fixed ratio.
2) The definition of compound is a pure substance formed by chemical bonding of two or more fifferent elements. That means a defined ratio of the elements in the compound, which conferes uniform and equal properties to every part of the compound.
Some examples of compounds are salt (NaCl), water (H2O), vinegard (CH3 COOH).
A mixture combines several elements or compounds, not bonded by chemical bonds but mixed in ratios which may vary.
