Chemistry
1 answer:
zlopas [31]3 years ago
8 0

Answer:

6.022 × 10²³ molecules of B₂H₆

Explanation:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

B₂H₆ molecules:

21.63 g = one mole of B₂H₆= 6.022 × 10²³ molecules of B₂H₆

Option D:  Chromium would require the most energy to convert one mole of gaseous atoms into gaseous ions each carrying two positive charges.

<h3>What does the term “ionization energy” mean? </h3>

The ionization energy measures an element’s ability for participating in any chemical processes that calls up for the creation of ions or the donation of other electrons.

It is defined as the energy that any electron present in a gaseous atom or ion has in order to absorb so that it comes out of the influence of the nucleus and hence freely move

Ionization energy is also said as the minimum energy required to remove the most loosely bound electron that is present in an isolated gaseous atom or a positive ion or a molecule.

It can be easily connected to the type of chemical bonds that exist between the components in the compounds that they form.

<h3>Which element ionizes most energetically?</h3>

Helium, because it has the highest first ionization energy, whereas francium has one of the lowest.

Burning gas on a stovetop transforms chemical energy into what other types of energy?
svp [43]

<u>Answer:</u>

<em>Burning gas on a stove top transforms chemical energy into thermal energy.</em>  

<u>Explanation:</u>

Cooking food involves in two types of energies. <em>They are chemical energy and thermal energy. </em>

We use gas for a gas stove.Here gas is chemical energy.when we light the stove the fire lits up and here the <em>chemical energy energy is converted into thermal energy.</em>

Breaking and combining of bonds during combustion gives heat and light.This thermal energy heats the vessels and cooks the food through the <em>process of conduction, convection and radiation. </em>
