Answer:
Stoichiometry
Explanation:
You have to use the stoichiometry rules. Remember that concentracion is the same as moles divided by the volume in the system
C = n/V
Also, that amount of moles is equal to mass divided by the molarmass
The nucleus is where the protons and neutrons are found. the mostly space electron cloud is where the electrons are found, surrounding the nucleus.
Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse.
The triangles are similar (right triangles which share an angle (A), so...
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2
Answer:
The sublimation energy
Explanation:
When an ionic solid turns into a gas it is changing from solid state to gas state without going throught liquid state. This process is called sublimation and the energy will be equal to
From start:
Joule, J, calorie,
Example 1: 120 J / 4.184 = 28.68 cal
Example 2: 1200 cal * 4.184 = 5020.8 J
