According to Charles's law, under which conditions will the volume of a given amount of gas be proportional to temperature?

2 answers:

7 0

The Charles's Law states that the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. Hope this helps. Have a wonderful day.

Elden [556K]

Answer:

When copper(II) chloride and sodium carbonate solutions are combined, solid copper(II) carbonate precipitates, leaving a solution of sodium chloride. Write the conventional equation, total ionic equation, and net ionic equation for this reaction.

Explanation:

The word equation for the reaction is:

Copper (II) chloride(aq) + sodium carbonate (aq) ->sodium chloride (aq) + copper carbonate(s)

The balanced chemical equation of the reaction is:

$CuCl_2(aq)+Na_2CO_3(aq)->2NaCl(aq)+CuCO_3(s)$

The complete ionic equation is:

$Cu^2+(aq)+2Cl^-(aq)+2Na^+(aq)+CO_3^2^-(aq)->2Cl^-(aq)+2Na^+(aq)+CuCO_3(s)\\$

The net ionic equation is obtained from the complete ionic equation after removing the spectator ions:

$Cu^2^+(aq)+CO_3^2^-(aq)->CuCO_3(s)$

Zinc phosphide, Zn3P2, is often used as a rat poison. Phosphorus has 5 valence electrons. How many valence electrons does each z

Helen [10]

The choices that should have accompanied this question were:
A. 1
<span>B. 2 </span>
<span>C. 3 </span>
<span>D. 4
</span>
My answer is B. 2.
Below is an explanation, I found while doing the research.

<span>Phosphate needs 3 electrons each totaling 6 electrons so each zinc will need to give up 2 electrons.

Phosphate wants to imitate the electron configuration of Argon because noble configurations are the most stable. With P getting the extra electrons the valence shell will be 3s2 3p6, which is the same as Argon. Without the extra electrons, the P valence shell looks like this 3s2 3p3, now you can see why each phosphorus wants 3 more electrons, that will make it 3s2 3p6, just like Argon.</span>

How many moles of gas are present in 1.13 L of gas at 2.09 atm and 291 K?

raketka [301]

<h2><u>Answer:</u></h2>

n = 0.0989 moles

<h2><u>Explanation:</u></h2>

n = PV / RT

P = 2.09atm

V = 1.13L

R = 0.08206

T = 291K

Plug the numbers in the equation.

n = (2.09atm)(1.13L) / (0.08206)(291K)

n = 0.0989 moles
