What results in a chemical change?
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermicreactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science ofchemistry. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen. So much energy is released that the hydrogen gas released spontaneously burns in the air.
The rearranging of the chemical makeup of matter is called a what?
The rearranging of the chemical make-up of matter is called a chemical reaction. This is what will constitute a chemical change as it will alter the chemical composition.
What speeds up reactions?
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
Are chemical reactions useful?
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What is the chemical responsible for triggering allergic reactions in the body?
The chemical responsible for triggering allergic reactions in the body is called histamine.
How enzymes control chemical reactions?
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
What are molecules called that control all chemical reactions in the body?
Enzymes are molecules that control all chemical reactions in the body by catalyzing specific reactions. They act as biological catalysts and regulate the speed and specificity of biochemical reactions.
What is the substance called that helps chemical reactions happen in the body?
Enzymes are the substances that help chemical reactions occur in the body. These protein molecules act as catalysts, speeding up the rate of biological reactions without being consumed in the process.
Chemical reactions in the body take place in what nutrient?
Chemical reactions in the body take place in water.
Chemical reactions take place in the body in what nutrient?
Chemical reactions in the body take place in water.
What is a protein that helps run chemical reactions in the body?
Proteins involved in chemical reactions (speeding them up) are called enzymes. Note: most enzymes are proteins, but not all.
What accelerates chemical reactions that occur in the human body?
Enzymes are biological molecules that accelerate chemical reactions in the human body by lowering the activation energy needed for the reactions to occur. Enzymes are highly specific and work by binding to specific substrates to catalyze a specific reaction. Temperature and pH can also affect the rate of chemical reactions in the body.
How chemicals play an important role in the physiological aspect of the body?
Enzyematic reactions that occur from chemical reactions in the body speed up the activity and physiologically have everything to do with chemical reactions in the body.
Are reactions chemical?
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
What controls the rate of chemical reaction in human body?
The rate of chemical reactions in the human body is primarily controlled by enzymes, which are biological catalysts that help speed up reactions by lowering the activation energy needed for the reaction to occur. Enzymes can be regulated by factors such as temperature, pH, and the presence of inhibitors or activators. Additionally, the concentration of reactants and products in the body can also influence the rate of chemical reactions.
What refers to all of the chemical reactions in the body?
Metabolism refers to all of the chemical reactions in the body that involve breaking down nutrients to produce energy or building up molecules for growth and repair. It is a crucial process for maintaining life and carrying out essential bodily functions.
