What must be absorb before a chemical reaction can start by the reactants?
energy
What energy is needed to start a chemical reaction?
Activation energy is the energy needed to start a chemical reaction by breaking the existing chemical bonds in the reactants before new bonds can form in the products. This energy barrier must be overcome for the reaction to proceed.
Why is it important for people to chew their food thoroughly before swallowing?
Food digestion occurs through chemical and physical digestion. Physically, the teeth and tongue break down food, which combined with enzymes in saliva, breaks down food before it enters the stomach. Chewing food thoroughly allows the chemicals, which aid in digestion, to access a larger surface area to interact with. Physically breaking down food well decreases the chemical work your body must preform to break down food and increases nutritional absorption.
What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
What must fool be broken down into before it can pass into the blood stream?
Before food can pass into the bloodstream, it must be broken down into its basic nutrients through the processes of digestion. This involves mechanical breakdown in the mouth and chemical digestion in the stomach and intestines, where proteins are broken down into amino acids, carbohydrates into simple sugars, and fats into fatty acids and glycerol. Once digested, these nutrients are absorbed through the intestinal walls into the bloodstream for transport to cells throughout the body.
What must be known before a chemical equation can be written?
We need to know the reactants and products with their chemical formulas.
Difference between physical digestion and chemical digestion?
Physical (also called mechanical) digestion is when you use your teeth to mash up food. You are physically breaking the food into smaller pieces. However, chemical digestion would be what your saliva or stomach acids are doing. They are breaking down the food and transferring different parts of it (such as lipids etc.) to the different parts of your body that need it.
What age do kids in PA start school?
They must be 5 before September 1st, but can be as old as 8 before they start.
Why animals must have teeth?
So they can chew (to prevent choking) and enzymes (saliva-for digestion) for digestion.
What do you do before you start work on your Eagle Scout Project?
Before you can start work you must type a proposal and submit it to the eagle board of review
