Answer:
B. ΔG > 0, Q > K
Explanation:
For reverse reaction to take place Q should be greater than K
Since reverse reaction should be spontaneous, forward reaction should be non spontaneous.
So, for forward reaction, ΔG > 0
Hence, the correct answer is B
Answer:
Final pressure of the gas remaining in the first container is 3.5 atm
Explanation:
Since it is given that temperature is constant , we can apply -
PV=constant , where
P = Pressure of the gas
V = Volume of the container in which the gas is contained
Initially,
For container 1 -
= 4 atm
= 6 L
Finally,
For container 2 -
= 3 atm
= 1 L
For container 1 -
= ?
= 6 L
∴ = +
∴ 4×6 = (×6) +(3×1)
∴ = 3.5 atm
Answer:
Ordinary table salt is called sodium chloride. It is considered a substance because it has a uniform and definite composition. All samples of sodium chloride are chemically identical. Water is also a pure substance. Salt easily dissolves in water, but salt water cannot be classified as a substance because its composition can vary. You may dissolve a small amount of salt or a large amount into a given amount of water. A mixture is a physical blend of two or more components, each of which retains its own identity and properties in the mixture . Only the form of the salt is changed when it is dissolved into water. It retains its composition and properties.
Homogeneous Mixtures
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the substance is always the same. The amount of salt in the salt water can vary from one sample to another. All solutions would be considered homogeneous because the dissolved material is present in the same amount throughout the solution.
One characteristic of mixtures is that they can be separated into their components. Since each part of the mixture has not reacted with another part of the mixture, the identities of the different materials is unchanged.
An example of a general formula of an acid is
<span>HCl
This is called as hydrochloric acid or hydrogen chloride.
H represents for the atom of Hydrogen
and Cl represents for the atom of Chlorine
Since their charges are -1, and +1, it's ratio is 1:1</span>
Old and inefficient mining smokestacks contaminate the soil around abandoned mine sites.
<h3>What are mines?</h3>
A mine is an area from which natural resources are extracted such as coal, metals, etc. A mine is known to be the source of many heavy metals as well as acid.
