Group 7, the halogens.
The elements in this group form -1 ions; examples are chlorine and bromine.
An element is a substance that can not be broken down in simpler substances by chemical means. A compound is a substance that contains two or more substances that are chemically combined in a definite and fixed proportion by mass. A mixture is a combination of two or more substances which are not chemically combined. Mouthwash is an example of homogeneous mixture.
The answer would be 76.752 .
Answer: ATP is the energy currency molecule which is required for cellular processes.
Explanation:
When the cell require metabolic energy to perform a particular a task. From the ATP or adenosine triphosphate molecule one of three phosphate molecule gets displaced and liberates the resulting molecule becomes adenosine diphosphate or ADP. The phosphate molecule is used by the cell to perform different cellular and metabolic functions as a source of metabolic energy. The phosphate is released by the hydrolysis of the phosphoanhydride bond with the other phosphate group.
