please tell me about the change of color of chemical reaction?
BalasHapusProduces a Chemical Reaction Color Changes as Apples are cut and left for some time, over time will turn brown. This color change indicates that the chemicals in the apple have reacted with oxygen in the air. The reaction between starch solution and iodine tintur can be seen from the color change. A brightly colored starch solution, brown iodine. If both are mixed to form a blue color.
HapusGive an idea of the cause and effect of daily life?
BalasHapusThx.
Produce Gas Chemical Reaction
HapusIn everyday life, we face many chemical reactions characterized by gas formation. When the carbide is mixed with water, it will produce acetylene. This gas is generally used for the purpose of connecting metal with welding. In addition acetylene can also be used to speed up the ripening of the fruit. When baking, the dough into baking soda is added. As the dough is hot, baking soda that decomposes produces carbon dioxide gas. This gas causes the cake to rise.
emical reactions happen because?
BalasHapusFactors of chemical reaction Can be caused by several things:
HapusA. Happened by burning
B. Mixing of substances
C. Occurred due to electricity
One example of cause and effect learning is corrosion. Can you elaborate on the understanding of corrosion in metal and its control?
BalasHapusCorrosion very often we encounter in everyday life. Another name of corrosion is also called rust. Corrosion itself occurs in metal objects such as iron. Corrosion is the reaction between metal and the surrounding substances between air and air causing new compounds. In the newly proposed plantation is a reddish brown solid substance that is fragile and porous. The chemical formula of rust is Fe2O3.xH2O.
BalasHapusCorrosion occurs because of the reaction between the metal and the substances around it. In rust, rusting can occur because the humid air (oxygen and air) mengorosi (light) to the iron so that a new substance appears solid reddish-brown substance.
Corrosion event itself is an electrochemical process, ie a process (change / chemical reaction) that involves existence. Part of iron acts as a negative pole (negative electrode, anode), while the other part is a positive pole (positive electrode, cathode). Electrons flow from the anode to the cathode, so corrosion events occur.
Here are some ways you can do to prevent / slow down corrosion:
1.Paint
Paint can avoid direct contact between iron and moist air so that it can slow down corrosion. This method is usually done on doors, fences, iron pipes, and others.
2. Oil with oil
Oil spikes can add direct contact with water and moisture. This method is usually done on tools and machines.
3. Wrapped with plastic
This method is commonly used for example on dish racks and bicycle bikes.
