<span>Molecules are having the same chemical formula same number of atom but different three dimensional shapes are called <u>isomer</u>. Cis trans isomers maintain the same covalent partnerships,but atom may arranged differently.There are two or more compounds arranged in same molecular formula but different arranged atoms are seen in this molecule with different structure of it.</span>

How many atoms are there in 10.2 moles of Phosphorous?​
nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³  particles

Moles can also be determined from the amount of substance mass and its molar mass

  • number of atoms :

\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}

Describe the arrangement of atoms in a solid, liquid, and gas
dmitriy555 [2]
In a solid, atoms are packed very closely together, almost like an organized grid. They vibrate, and rub against each other, but stay in the same place.
 In a liquid, atoms are farther apart, and slide around each other, which is why if you pour water on the ground, it won't stay in any specific shape unless it is in a container. However it does stay together. Gas on the other hand is very spread out with a lot of space in between the individual atoms. All the space allows gases to expand and contract. Gas atoms bounce around, and will not hold a form or stay together.

In boyle's law, the initial volume of a gas is 120 ml at 256 kpa. what will be the volume if the pressure increases to 385 kpa?
Vinil7 [7]
<h3>Answer:</h3>

79.8 ml

<h3>Explanation:</h3>

Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.

Boyle's Formula

When describing the relationship between pressure and volume, the formula \displaystyle P_{1} V_{1}= P_{2} V_{2}. In this formula, P_{1}V_{1} is the initial pressure and volume. On the other side, P_{2} V_{2} is final pressure and volume. So, to find a missing variable you must plug in the values you are given.

Final Volume

Remember when solving this question to remain constant in your units. When we plug in the values we know we are given:

  • 256kPa*120mL=385kPa*V_{2} mL

Now, we can multiply the left side

  • 30720kPa*mL=385kPa*V_{2} mL

Finally, we can divide by 385 to isolate the final volume

  • 79.8mL=V_{2}

This gives the final volume of 79.8mL.
