This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:
P = P1 + P2 + P3
P = (82.0575 atm.cm^3/mol.K)( 298.15 K)/1.50 x 10^3 cm^3) x (<span>0.158 mole + 0.09 mol + 0.044 mol) = 4.76 atm</span>
<h2>Answer :2PbSO4 → 2PbSO3 + O2 </h2>
In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
i hope this helps in some way!
Answer: A solid has a defined shape and volume. A common example is ice.
A liquid has a defined volume, but can change state. An example is liquid water.
A gas has neither a defined shape nor volume. Water vapor is an example of a gas
Concave is not a type of mechanical wave because it doesn’t need a medium for propagation.
