Because science they need to know how food works and stuff like that u know?
Answer is: C. exothermic reactions.
For example, the Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃) and energy is released:
N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).
Answer:
A pH less than 7 is an acid, with number 1 indicating stronger acids
Explanation:
The pH scale has a range of 1 to 14. The following has been concluded on the pH scale:
1. Between 1 and 6 indicates an acid solution.
2. 7 indicates a neutral solution
3. Between 8 and 14 indicates an alkaline or basic solution.
Now with these information, we can answer the above questions as follow:
A pH less than 7 is an acid, with number 1 indicating stronger acids
<span>chemical combination of two or more elements in definite proportions. For example, two hydrogen molecules + one oxygen molecule= one water molecule. A solution is a physical combination of two or more chemicals mixed evenly (salt that is dissolved in water). Solutions are also known as homogenous mixtures. A mechanical mixture is a physical combination of two or more chemicals that are not evenly mixed (hot fudge on ice cream). </span>
Answer:
3 or more simple sugars combined
Explanation:
A polysaccharid molecules consist of a number of sugar molecules bonded together.
