When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.

<h3>What is a covalent compound?</h3>

A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.

One of the major factors that affect compounds with covalent bonds is temperature.

The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.

A solution at ph 10 contains __________ than the same amount of solution at ph 8.
Sindrei [870]

100 times less H+

A solution at ph 10 contains<u> </u><u>100 times less H+</u> than the same amount of solution at ph 8.

<h3>The pH scale: How does it function?</h3>
  • The pH scale determines how acidic or basic water is.
  • The range is 0 to 14, with 7 representing neutrality.
  • Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

<h3>How does the pH change when two acids are combined?</h3>
  • An acid's strength increases with the quantity of hydrogen ions it releases.
  • The pH of the strong acids is between 1 and 2.
  • We may observe that there is no response when two acids of the same strength are combined.
  • It's because the end product will be neutral and the pH won't change.

<h3>How is pH value determined?</h3>

There are two ways to measure pH:

  • colorimetrically with indicator fluids or sheets
  • electrochemically with electrodes and a millivoltmeter for greater accuracy (pH meter).

How to do limiting reagents for chemistry?
gavmur [86]
Balance the chemical equation for the chemical reaction.
Convert the given information into moles.
Use stoichiometry for each individual reactant to find the mass of product produced.
The reactant that produces a lesser amount of product is the limiting reagent.
The reactant that produces a larger amount of product is the excess reagent.
To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given.
