Determine each type of reaction. 2 C 2 H 2 ( g ) + 5 O 2 ( g ) ⟶ 4 C O 2 ( g ) + 2 H 2 O ( l ) 2CX2HX2(g)+5OX2(g)⟶4COX2(g)+2HX2O
Valentin [98]

Answer:

2 C 2 H 2 ( g ) + 5 O 2 ( g ) ⟶ 4 C O 2 ( g ) + 2 H 2 O ( l )- combustion reaction

N H 4 N O 3 ( s ) ⟶ N 2 O ( g ) + 2 H 2 O ( l )- decomposition reaction

C O ( g ) + 2 H 2 ( g ) ⟶ C H 3 O H ( l ) - combination reaction

2 F e ( s ) + 6 H C l ( a q ) ⟶ 2 F e C l 3 ( a q ) + 3 H 2 ( g )- Redox reaction

C a C l 2 ( a q ) + N a 2 C O 3 ( a q ) ⟶ 2 N a C l ( a q ) + C a C O 3 ( s )- double displacement reaction

Explanation:

We can determine the type of reaction by considering the reactants and products.

Combustion is a reaction between a substance and oxygen which produces heat and light. The first reaction is the equation for the combustion of ethyne.

A decomposition reaction is one in which a single reactant breaks down to form products. The second reaction is the decomposition of ammonium nitrate.

A  combination reaction is said to occur when two elements or compounds react to form a single product. The third reaction is the combination of carbon dioxide and methane to form  methanol.

An oxidation-reduction reaction is a reaction in which there is a change in oxidation number of species from left to right of the chemical reaction equation. The fourth reaction is the oxidation of iron (0 to +3 state) and reduction of hydrogen (+1 to 0 state).

A double displacement reaction is a reaction in which ions exchange partners from left to right in the reaction equation. The fifth reaction is a double displacement reaction. Both Na^+ and Ca^2+ exchanged partners from left to right of the reaction equation.

Nonelectrolytes fail to ionize or dissociate in water because
soldier1979 [14.2K]
Nonelectrolytes fail to ionize or dissociate in water becausethey are very strongly bonded to each other. Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. Hope this answers the question. Have a nice day.

____ [38]

Answer:

La afirmación es verdadera.

Explanation:

El método científico es un método de  investigación usado principalmente en la producción de conocimiento en las ciencias y se define como un procedimiento para tratar un conjunto de problemas. En ciencia, el método científico es la estrategia para la investigación y la exploración de lo desconocido.

Por lo que el método científico es el procedimiento mediante el cual es posible alcanzar un  conocimiento objetivo de la realidad, tratando de dar respuesta a las interrogantes  acerca del orden de la naturaleza.

Para ser científico, un método de investigación debe basarse en la empírica y en la  medición, sujeto a los principios específicos de las pruebas de razonamiento.

El método científico se basa en la reproducibilidad, es decir, la  capacidad de repetir un determinado experimento, en cualquier lugar y por cualquier  persona, y la refutabilidad,  es  decir toda proposición científica tiene que ser susceptible de  ser falsada o refutada.

Entonces <u><em>la afirmación es verdadera.</em></u>
