1.) When blood flow is gone from the extremities for too long, the cells start to die. Depending on the severity of the

Without doing any calculations it is possible to determine that silver chloride is more soluble than ACD, and silver chloride is less soluble than ___.

It is not possible to determine whether silver chloride is more or less soluble than B by simply comparing Ksp values.

Explanation:

The Lead (Pb) is a heavy metal and Zinc (Zn) is a transition metal, both combine with the anion phosphate produces heavy complexes very insoluble.

The silver cation (Ag+) is an acid cation which in basic conditions rapidly precipitates as AgOH which is highly insoluble and unstable.

The FeCO3 is a complex with a solubility relatively close between AgCl. The Kps of these two are $3.2x10^{-11}$ and $1.8x10^{-10}$ respectively at room temperature.

A 5.0L container is filled with H2 gas at STP. Predict what happens with the conditions of the gas change as described below (in

Amiraneli [1.4K]

Answer:

(a) As temperature increases, the average kinetic energy increases

(b) If H₂ is replaced with N₂, there will be increase in average velocity

(c) An increase in temperature will cause increase in average velocity

(d) The increase in entropy as a result of an increase in temperature and average velocity will cause the kinetic energy to increase.

Explanation:

Given;

5.0L container filled with H₂ at stp

Part (a) What happens to average kinetic energy as temperature increases

As temperature increases, the average kinetic energy increases

Part(b) What happens to the average velocity if H₂ is replaced with N₂

Entropy is directly proportional to average velocity of gases and entropy increases with an increase in molecular mass.The molecular mass of nitrogen gas N₂ is greater than molecular mass of hydrogen gas H₂.

Thus, if H₂ is replaced with N₂, there will be increase in average velocity.

Part(c) What happens to the average velocity as temperature increases

Kinetic energy increases with an increase in temperature and average velocity.

An increase in temperature will cause increase in average velocity

Part (d) What happens to average kinetic energy if H₂ is replaced with N₂

The increase in entropy as a result of an increase in average velocity will cause the kinetic energy to increase.
