Directions: Write the name of the type of chemical reaction in the space provided.(Can be Synthesis Reaction, Decomposition Reaction, Combustion, Single Displacement Reaction or Double Displacement Reaction)

Answers

The given reactions are combination reaction, decomposition reaction, neutralization reaction, displacement reaction and double displacement reaction.

What is displacement reaction?

A displacement reaction is a chemical process during which a one more reactive element being replaced from its compound by a less reactive element.

What is combination reaction?

When A combination reaction occurs when one or more elements or compounds react together to generate a new chemical. Equations of the following kind are used to depict such reactions.

X+ Y→XY

6) $Fe}(s)+3{O}_(2)(g)$ → $2{Fe}_(2) {O}_(3)(s)$ , this reaction is a kind of combination reaction reaction.

7) ${Zn}_(2)(s)+2 {HCl} (aq)$ → ${ZnCl}_(2)(a q)+{H}_(2)(g)$

This reaction is a kind of displacement reaction.

8) ${MgCO}_(3)(a q)+2 {HCl}(a q)$ → ${MgCl}_(2)(a q)+{H}_(2) {O}(l)+{CO}_(2)(g)$ .

This reaction is a kind of combustion reaction.

9) ${NiCl}_(2)(s)$ → ${Ni}(s)+{Cl}_(2)(g)$ .

This reaction is a kind of decomposition reaction.

10) ${C}(s)+6 {H}_(2)(g)+{O}_(2)(g)$ → $2 C}_(2) {H}_(6) {O}(s)$ .

This reaction is a kind of combination reaction.

11) $\mathrm{C}_(12) \mathrm{H}_(22) \mathrm{O}_(11)(s) \rightarrow 12 \mathrm{C}(s)+11 \mathrm{H}_(2) \mathrm{O}(\mathrm{g})$ .

This reaction is a kind of dissociation reaction.

12) $2 \mathrm{LiI}(a q)+\mathrm{Pb}\left(\mathrm{NO}_(3)\right)_(2)(a q) \rightarrow 2 \mathrm{LiNO}_(3)(a q)+\mathrm{PbI}_(2)(s)$ .

This reaction is a kind of double displacement reaction.

13) $\mathrm{CdCO}_(3)(s) \rightarrow \mathrm{CdO}(s)+\mathrm{CO}_(2)(g)$ .

This reaction is a kind of decomposition reaction

14) $\mathrm{Cl}_(2)(g)+2 \mathrm{KBr}(a q) \rightarrow 2 \mathrm{KCl}(a q)+\mathrm{Br}_(2)(g)$ .

This reaction is a kind of single displacement reaction.

15) $\mathrm{BaCl}_(2)(a q)+2 \mathrm{KIO}_(3)(a q) \rightarrow \mathrm{Ba}\left(\mathrm{IO}_(3)\right)_(2)(s)+2 \mathrm{KCl}(a q)$ .

This reaction is kind of double displacement reaction.

16) $2 \mathrm{Mg}(s)+\mathrm{O} 2(\mathrm{~g}) \rightarrow 2 \mathrm{MgO}(s)$ .

This reaction is a kind of combination reaction.

17) $AgNO_(3) (aq) +KI(aq)$ → $KI(aq) + KNO_(3)(aq)$ .

This reaction is a kind of double displacement reaction.

18) $2 \mathrm{Li}(s)+\mathrm{H}_(2) \mathrm{O}(b) \rightarrow 2 \mathrm{LiOH}(a q)+\mathrm{H}_(2)(g)$ .

This reaction is a kind of single displacement reaction.

19) $\mathrm{C}(\mathrm{s})+\mathrm{O}_(2)(\mathrm{~g}) \rightarrow \mathrm{CO}_(2)(\mathrm{~g})$ .

This reaction is a kind of combination reaction.

Answers

Answer : Option A) Dry media

Explanation : i) Dry media is a media that deposits graphite, charcoal, pastels, ordinary pencils, then moistened with a wet brush to get various painterly effects on the paper fibers.

ii) Silverpoint - Silverpoint media uses red chalk or traces of black pencil on white-coated paper usually the manuscripts,

iii) Ink Painting - Uses various inks on the paper.

iv) Liquid media - uses liquid pigments suspended in some base which in liquid state that soaks the paper.

Dry media is a media that consists of natural or synthetic mineral or plant substances that deposit crystalline or splinter-like fragments in the paper fibres.

When the first periodic table of the elements was published, the elements were arranged by atomic mass. Although several elements seemed out of order, later discoveries showed the order to be correct. Which event most likely helped the development of the periodic table?

Answers

Answer;

New information changed the understanding of the atom’s structure.

Explanation;

Mendeleev is know as the Father of the Modern Periodic Table. His table allowed scientists to predict the existence of elements that hadn't been discovered.
Mendeleev saw that when the elements were arranged in order of increasing atomic mass, those that had similar properties occurred in a repeating pattern. He predicted that elements yet to be found would fill the gaps in his table.
