To increase a gas ' average kinetic energy must do what?

1 answer:

5 0

The kinetic energy of a gas is a measure of its Kelvin temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy. Lighter gas molecules move faster than heavier molecules.

For each of the following, predict the complete, balanced chemical equation for the reaction that occurs when they are mixed. Ma

Damm [24]

Answer:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Explanation:

Hello there!

In this case, according to the given chemical reactions, it is necessary to keep in mind the cations and anions are switched around as a result of the bonds rearrangement in these neutralization reactions; therefore, we can proceed as follows:

1. The balanced chemical reaction is:

$HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.

2. The balanced chemical reaction is:

$2HI(aq)+Sr(OH)_2(aq)\rightarrow SrI_2(aq)+2H_2O(l)$

Because all atoms are in the same amount at each side of the equation and the resulting salt is soluble.

Best regards!

John has a solution with a pH of 12.21. what is the hydrogen ion concentration of this solution?

Georgia [21]

Answer:

In this way, ph is determined by hydrogen ion concentration . In the case of neutral solution [H+] =10-7 which we call a ph of 7. This means, for example, that a hydrogen-ion concentration of a solution with a ph of 4 is 10-4 mol/l, meaning it contains 0.0001 mole of hydrogen ion in a solution of 1 liter.

In an experiment, a student made a compund of sulfur and copper, and now she needs to find if the compound is copper (I) sulfide

finlep [7]

Answer: The formula for the given compound is $Cu_2S$

Explanation:

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal.

The chemical formula of copper (I) sulfide is $Cu_2S$ because this is formed by the combination of $Cu^+$ ions and $S^{2-}$ ions
