Answer:
KCl ⇒ 1.205x10²⁴ molecules
O₂ ⇒ 1.807x10²⁴ molecules
KClO₃ ⇒ 1.205x10²⁴ molecules
Explanation:
In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states <em>the number of particles in one mol</em>:
- In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).
So now we <u>multiply the number of moles of each substance by Avogadro's number</u>:
- KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
- O₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ molecules
- KClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
Answer:
It is higher than that of water
Explanation:
Because we now know that through experimentation, the new compound has a higher and stronger hydrogen bonds than water, the specific heat capacity will be higher.
Specific heat capacity is the amount of heat needed to raise the temperature of a unit mass of as substance by 1°C.
- This property is a physical property of matter .
- Most physical properties are a function of intermolecular forces in a compound.
- Since hydrogen bond is a very strong intermolecular force, the specific heat capacity will be stronger for the compound discovered.
- This implies that it will require more heat to raise the temperature of a unit mass of this compound by 1°C.
Answer:
d. 117 grams
Explanation:
The mass of the table salt produced will be 117 grams.
Chemical reactions obey the law of conservation of mass. In this regard, matter is neither created nor destroyed in the course of a chemical reaction. It is expected that the mass of the reactants and products remain the same.
The reaction expression:
2Na + Cl₂ → 2NaCl
So, mass of sodium = 46g
mass of chlorine formed = 71g
Mass of NaCl = 46 + 71 = 117g
A way to explain it is that back then all the continents were together but soon after drifted apart the were in the same place sort of put they drifted apart so that's sorta what happened. Hope that helps a little
Bonding MO's have lower energy than antibonding MO's. The bonding MO's lower energy, even lower than its constituent atomic orbitals, accounts for the stability of a molecule in relation to its individual atoms. However, the sum of energy of the MO's must equal the sum of energy of the AO's.
<h3>What is atomic orbital?</h3>
An atomic orbital is a function in atomic theory and quantum mechanics that describes the location and wave-like behavior of an electron in an atom. This formula can be used to calculate the likelihood of locating any atom's electron in any given location surrounding the nucleus. The phrase atomic orbital can also refer to the actual region or place where the electron is projected to be present given the orbital's mathematical form.
Each orbital in an atom is defined by a set of values of the three quantum numbers n, l, and ml, which correspond to the energy, angular momentum, and an angular momentum vector component of the electron, respectively (magnetic quantum number).
