Answer:

Gas to liquid

Explanation:

As the atoms temperature decreases, the kinetic energy of the atom decreases. Besides if it is turning to solid the atoms will be fixed position,they wont pass each other. So it here is forming to become a liquid

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press

Simora [160]

Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

$P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L$

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

Have a nice day!

If a block has the mass of 15.00 grams and measurements of 5.00cm by 3.00cm by 2.00cm what is the volume of the block?

Natalija [7]

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

<h3>Volume = 30cm³</h3>

What is the standard potential, e∘celle∘cell, for this galvanic cell? use the given standard reduction potentials in your calcul

Olin [163]

The standard potential for the given galvanic cell is 0.477 V

<h3>What is electrode potential?</h3>

The electrode potential is the electromotive force of a galvanic cell built using a standard reference electrode and another electrode whose potential is to be found.

There are two types of electrode potential

Oxidation potential - The potential associated with oxidation reaction is known as oxidation potential

Reduction potential - The potential associated with reduction reaction is known as reduction potential

At the anode, oxidation occurs

$Sn(s)\rightarrow Sn^{2+}(aq)+2e^-$

At the cathode, reduction occurs

$Cu^{2+}(aq)+2e^-\rightarrow Cu(s)$

$E^o_{cell} =E^o_{cathode} -E^o_{anode}$

= 0.337 - (-0.140)

= 0.477 V

Thus, The standard potential for the given galvanic cell is 0.477 V

Classify the reactions as endothermic or exothermic.

solong [7]

A - Endothermic. This is because it absorbs heat rather than releases it.

B - Exothermic. It's releasing heat which in turn makes the beaker hot.

C - Endothermic. The Ammonium Chloride is absorbing the heat away from the beaker.

D - Exothermic. To produce nuclear energy, it needs to release heat.

E - Endothermic. The hydrogen and oxygen atoms are absorbing the heat given off from the electric current.

F - Exothermic. It is producing heat or releasing heat.

Exothermic is the losing, release, or production of heat. Endothermic is the exact opposite; it is the storing of heat.

Hope this helps!
