<span>The ideal gas law.
PV=nRT
pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273)
Original data
Pressure 1 atmosphere
Volume 1 liter
Temp 25C = 298K
New data
Volume 0.5 liter
pressure X
Temp 260C = 533K
P1v1T1 = P2v2T2
plug and chug.
(1)(1)(293) = (x)(0.5)(533)
Solve for X, which is the new pressure. </span>
Answer: homogeneous
Explanation: The taste of soda water is constant till the end. The carbon dioxide is dissolved homogeneously in soda water.
1.54 x 10^-10 (ten to the negative tenth power)
PH = -log [H+]
pH = -log (1.0x10^-4) = -(-4) = 4 or A
The correct answer is B.
1 mol O2 x 15.999 O2/ 1 mol O2 = 15.999 O2
16 O2 when rounded.
