Answer:
7.0*10-11m or 70Å
Explanation:
From Bragg's equation, w=2dsinx/n
Since all the parameters are specified in the question, we can easily go ahead to obtain the wavelength but we must convert the spacing given in angstroms to meters using the conversion factor provided as shown in the solution below:
A chemical reaction occurs when reactant particles collide with proper energy and proper orientation.

A. Identify the properties as either a physical or chemical property. (first 3 are chemical, last is physical)
The answer is D, the attractive force between them decreases.
Although the volume that the particles take up generally increases when going from solid to liquid, particles themselves never change their size. It’s the attractive force that decreases and doesn’t pull the particles together as tightly when a solid changes to liquid.
