650.j is the same amount of energy as? 2720cal1550cal650.cal2.72cal

650 J are 155 calories

Explanation:

In the world, there are many differents ways to express energy. For example, for SI base units, Joule (J) is the correct way to express energy. But it is common the use of other units in differents fields. In this case, we need to convert Joules to calories. The conversion is:

4,1845 J = 1 cal

Thus:

650 J × (1 cal / 4,1845 J) = 155 cal

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
