Ryan and Abigail are conducting an experiment. They place six ice cubes into a beaker and find the combined mass. They allow the ice cubes to melt and find the combined mass of the beaker and the liquid water. A
A
Before
After
What can the students expect to be true about the two masses?
The mass of the ice cubes will be greater because solids are more dense.
The mass of the ice cubes will be greater because they took up more space in the beaker.
The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker
The mass of the ice cubes and the water will be equal because their particles have the same amount of energy

Answer///an early form of the atomic theory; dalton atomic theory;

Oxygen= 88ghydrogen= 12g

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

The answer is the third choice
