Based on the observation, the type of change which took place in this scenario is a physical change.

<h3>What is a Physical change?</h3>

This is the process in which several reactions don't alter the chemical composition of substance.There may be however changes in its form or phase such as the conversion of water to vapor which moves from the liquid phase to the gas phase.

In the experiment, we observed the formation of bubbles which means boiling of the water droplets took place hence the presence of vapor as a result of the elastic collision of the molecules which resulted in its formation.

How many moles of helium are needed to fill a balloon to a volume of 5.3 L at 22 ℃ and 632 mmHg?
son4ous [18]

Answer:

0.18 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

Given: V = 5.3 L, T = 22 °C = (22+272) K = 295 K, P = 632 mmHg = (0.00131579×632) = 0.8316 atm,  R = 0.083 L.atm/K.mol

Substitute these values into equation 2

n = (0.8316×5.3)/(0.083×295)

n = 0.18 moles

Magma can partially crystallize at depth and then rise to shallow depths where the remaining magma solidifies. The early-formed
Doss [256]
<h2>Phenocrysts and Porphyritic texture </h2>

Explanation:

  • The early formed crystals are of phenocrysts and the texture of these crystals is porphyritic texture.  
  • This crystallization occurs when early-forming plagioclase crystals which are rich in calcium start coating with plagioclase crystals which are rich in sodium.
  • On cooling, the magma is then processed in a volcanic eruption, after the eruption the liquid which is left behind will start cooling and forms a porphyritic texture.

The central Xe atom in the XeF4 molecule has ________ unbonded electron pair(s) and ________ bonded electron pair(s) in its vale
Dimas [21]

Answer:

Lewis structure in attachment.

Explanation:

Atoms of elements in and beyond the third period of the  periodic table form some compounds in which more than eight electrons surround the  central atom. In addition to the 3s and 3p orbitals, elements in the third period also  have 3d orbitals that can be used in bonding. These orbitals enable an atom to form  an <u>expanded octet</u>.

The central Xe atom in the XeF₄ molecule has <u>two</u> unbonded electron pairs and <u>four</u> bonded electron pairs in its valence shell.
