Arnold kept a water log as a project for his chemistry class. Arnold's family consists of Arnold, his sister, and his parents fo
r a total family size of four. He measured each family member's water usage every day for a week, and found that the family used an average of 457 gal/day. Arnold's city charges $0.223/cgal of water. The unit centigallon (cgal) is used by cities to measure the volume of water used, where 1 cgal is equal to 100 gal. Assuming this average usage continues, how much does Arnold expect his family to pay in a year for water usage?
Number of proton present in the nucleus determines the atomic number of an element. It determines <span>chemical properties, which is why all atoms with proton count (atomic number) 6 are carbon</span>
