Fynjy0 [20]2 years ago
5 0

Answer:

A pure element is a pure substance that has only one kind of atoms. If a substance is present in nature in elemental form, it means that the element is not very reactive as reactive elements exist in the form of their compounds with atoms of other elements. Element can be categorized as a metal or a non-metal based on some physical observable properties. Generally, metals are shiny lustrous solids and nonmetals are gases. Metals are good conductors of heat and electricity whereas nonmetals are not conductors.

What is meant by the term chemical reaction​
pantera1 [17]

Answer:

<h3>\huge{ \underline{ \underline { \bold{ \sf{ \orange{See \: below}}}}}}</h3>

Explanation:

▪️\underline{ \bold{ \sf{ \blue{Chemical \: reaction}}}}

⇒The composition , decomposition or displacement of molecules of matter during chemical change is called chemical reaction.

▪️\underline{ \bold{ \sf{ \purple{ \: Further \: more \: explanation}}}}

Various conditions bring about these changes. The chemical reactions are represented by chemicalequation. The compounds or elements that take part in chemical reaction are called reactant. They are written at the left side of an arrow that represent a change while the compound or elements that formed after the chemical change are called product. They are written at the right side of the arrow.

▪️\underline{ \bold{ \sf{ \purple{For \: example}}}}

When nitrogen reacts with hydrogen to form ammonia :

Nitrogen + Hydrogen ⇒ Ammonia

N₂ + 3H₂ ⇒ 2NH₃

<u>Presentation </u><u>of </u><u>a </u><u>chemical </u><u>reaction </u><u>in </u><u>the </u><u>form </u><u>of </u><u>equation </u><u>is </u><u>called </u><u>chemical </u><u>equation </u>. <u>Chemical equation may be word equations or formula equations.</u>

Hope I helped!

A high pH value indicates _____.
Mumz [18]

Answer:

A high pH value indicates a high concentration of OH- ion

Explanation:

The higher the OH- ion concentration high will be the pH.In simple words if the concentration of OH- ions are increased then the pH of the solution will also increase which means the solution will turns towards basic with increasing its OH- ion concentration.

  Let us assume that the OH- concentration of a solution is  10-9  so the pOH of that solution will be 9 and the pH will be 5.

  Now the concentration of OH-ion of that solution is increased from 10-9 to 10-8 now the pOH of that solution is 8 and the pH is 6.
