What kind of reaction is 2 c2h2 5 O2 → 4 co2 2 h2o?

What kind of reaction is 2 c2h2 5 O2 → 4 co2 2 h2o?

Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction. We also see from the RxN that is is a double replacement reaction.

What is the balanced equation of hydrogen peroxide?

H2O2 = H2O + O2 – Chemical Equation Balancer.

Which of the following is not an indication of a chemical reaction?

Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring.

What type of reaction is the generic equation?

Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds. The generic equation for a synthesis reaction is A + B à AB, where A and B are the pieces that make up the compound/molecule AB. The generic equation for a decomposition reaction is AB à A + B.

Which of the following is an example of a chemical reaction?

A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

What are the evidence of a chemical reaction?

How can I tell if a chemical reaction is occurring? A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change.

What are the 4 types of evidence of a chemical reaction?

Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.
