Answer:

The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. ... Alkali metals have low electronegativities. They react readily with nonmetals, particularly halogens.

Ionic crystals can form when metallic atoms bond with nonmetallic atoms. Which of the following is an example of an ionic crysta

Vanyuwa [196]

NaOH is an example of an ionic crystal.

Option a

<h3><u>Explanation:</u></h3>

Sodium Hydroxide is a "white solid ionic compound" consisting of sodium cations Na+ and hydroxide anions $OH^-$ . If we look at the crystal structure of NaOH, we can see that it has the combinations of ionic and covalent bonds. The bond that is shared between Oxygen ( O ) and Hydrogen ( H ) is the covalent bond.

The Sodium ( Na ) is bonded with an "ionic bond to the hydroxide part of the compound". NaOH is an ionic solid because it is formed by the combinations of metal and non-metal. When the crystal of NaOH is dissolved in water it dissociates into Na+ ions (which is ionic in nature) and $OH^-$ ions which bonds ionically to the other compounds.

How many elements and how many atoms are in MgCI2

aliina [53]

Answer: two elements and three atoms

Explanation:

An element is the simplest substance and hence cannot be broken down using chemical reactions.

Magnesium chloride $(MgCl_2)$ is an ionic compound formed by the transfer of electrons from element magnesium (Mg) to element chlorine (Cl) where Magmesium forms a cation $Mg^{2+}$ by losing two electrons and chlorine forms an anion $Cl^{-}$ by gaining electron.

There are 3 atoms in Magnesium chloride $(MgCl_2)$ which include one atom of magnesium (Mg) and two atoms of chlorine (Cl).

How to solve a balanced equation

geniusboy [140]

Explanation:

To balance a chemical equation, there are so many approaches to solve the problem.

A balanced chemical equation is one that obeys the law of conservation of matter.

According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".

This implies implies that equal number of atoms must be on both sides of the equation.

There are two main approaches to balancing chemical equation;

Inspection
mathematical equation

We can inspect the equation and affix the proper coefficients to combining species.

Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:

For example:

H₂ + O₂ → H₂O

mathematically;

aH₂ + bO₂ → cH₂O

conserving:

H : 2a = 2c

O: 2b = c

let a = 1

c = 1

b = $\frac{1}{2}$

multiply by 2 to give;

a = 2, b = 1 , c= 2

2H₂ + O₂ → 2H₂O
