Ionic compounds are formed from metal and non-metal elements
<h3>Further explanation</h3>
The chemical formula of compounds (especially ionic compounds) can be determined from the charge of each ion.
Determination of the ionic charge of the constituent elements of the compound can be seen from the electron configuration to achieve stability according to the octet rule
The charge of each ion will be crossed in the compound
Aluminum bromide
Al³⁺ + Br⁻ ⇒ AlBr₃
Magnesium bromide
Mg²⁺ + Br⁻ ⇒ MgBr₂
Sodium sulfide
Na⁺ + S²⁻ ⇒ Na₂S
Sodium nitride
Na⁺ + N³⁻ ⇒ Na₃N
Answer:
Zero-Order
Explanation:
The exothermic decaying of nitrous oxide at 575° C will lead to as follows:
→
<u>Hot platinum wire in the above reaction would function as a catalyst in the zero-order</u>. However, if the reaction is considered in the gaseous phase, it will be more inclined towards second-order.
In the given scenario( → ), <u>the reactant molecules of Nitrous oxide are restricted to the ones which have linked themselves to the catalyst's surface. Once this limited surface is filled, the extra molecules of gas would remain vacant until the previously attached molecules with the surface are decayed entirely</u>.
Yes since for atoms to be of the same element , they must have the same number of protons inside their nucleus . This means that 1- they will all have the same nucleon number ( mass number ) and that 2-they will all have the same number of electrons in their outermost shell which determines the chemical properties of the atom.

Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
