Answer:
It would be gas b. The gas you are talking about is carbon dioxide and for the reaction to work the gas needs to be bubbled through into the lime water.
Explanation:
The carbon dioxide reacts with lime water which is a solution of calcium hydroxide to form the white precipitate of calcium carbonate CaCO 3.
Let A be the 80% solution and B be the 20% solution and P be the produce solution of 70%. Va and Vb and Vp are the volumes of A and B and P respectively.
Va + 60 = Vp
0.7Vp = 0.8Va + 0.2(60)
Substituting the value of Vp from the first equation:
0.7(Va + 60) = 0.8Va + 12
30 = 0.1Va
Va = 300 gallons
Answer:
V = 1.79 L
Explanation:
Given data:
Volume of gas = ?
Number of moles of gas = 0.080 mol
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × V = 0.080 mol × 0.0821 atm.L/ mol.K × 273.15 K
V = 1.79 atm.L / 1 atm
V = 1.79 L
Answer:
A compound is just pure that is composed of elements that are chemically bonded in definite proportions
andd solution is umm well its a homogenous so basically saying
that it all just stays the same all the way through
Explanation:
im not sure how else to explain it haah hope this helped :P
