Answer : Option A) a tiny fragment or piece of matter particle.

Explanation : 
Atom are the tiny particles of a matter including particles; <span>The definition of an atom can be stated as the smallest component of any element, which can be characterized by sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons. </span>

OK so i did the test and got it 100% so (Atom - the basic...) (Element - a substance...) (Particles - a tiny...) and ( Phase - a unique...)

Partner Namets) For each of the following reactions carried out: Write the balanced chemical equation, the full ionic equation,
torisob [31]

Answer : The full balanced ionic equation will be,

2KI(aq)+Pb(NO_3)_2(aq)\rightarrow 2KNO_3(aq)+PbI_2(s)

Reactants are lead nitrate and potassium iodide.

Products are lead iodide and potassium nitrate.

The spectator ions are, K^+,NO_3^-

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

When potassium iodide react with lead nitrate then it gives potassium nitrate and lead iodide as a product.

The full balanced ionic equation will be,

2KI(aq)+Pb(NO_3)_2(aq)\rightarrow 2KNO_3(aq)+PbI_2(s)

The ionic equation in separated aqueous solution will be,

2K^+(aq)+2I^{-}(aq)+Pb^{2+}(aq)+2NO_3^{-}(aq)\rightarrow PbI_2(s)+2K^+(aq)+2NO_3^{-}(aq)

In this equation, K^+\text{ and }NO_3^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

Pb^{2+}(aq)+2I^{-}(aq)\rightarrow PbI_2(s)

Energy is involved in some way in all chemical reactions. Which type of reaction involves the absorption of energy from the surr
storchak [24]

Answer:

endothermic reaction

Explantion:

The definition for endothermic is:

describing a process that involves the absorption of energy from the surroundings by substances undergoing change.

Think of <em>en-</em>dothermic as energy entering and <em>ex-</em>othermic as energy exiting.

What can you conclude from the fact that electrons orbit far away from atomic nuclei?
suter [353]
Electrons are extremely small. Atoms are comprised mostly of empty space. Protons have a positive charge.
Hope this helps.
