Ground state, since electrons want to be in the lowest energy position as possible, which is closer to the nucleus of the atom.
The simplest compound of hydrocarbon is methane
- The formula is CH_4
- It belongs to alkane group and has single bonds.
The electron structure attached
Explanation:
The given data is as follows.
Mass of evaporating dish = 3.375 g
Total mass = Mass of solid sample + evaporating dish
That is, Mass of solid sample + evaporating dish = 26.719 g
Therefore, we will calculate the mass of solid sample as follows.
Mass of solid sample = (Mass of solid sample + evaporating dish) - mass of evaporating dish
= 26.719 g – 3.375 g
= 23.344 g
Thus, we can conclude that mass of his solid sample must be 23.344 g.
Answer:
Oceanic crust moves easly. Continental crust does not move
Answer:
Explanation:
Speed multipliers are useful when an object needs to move a further distance or at a higher speed. Some examples are wheels and axles and third class levers. Machines can be either simple or complex. Simple machines are machines that only use one type of machine, such as a lever or an inclined plane.
