If there are 2 electrons in the same orbital, the spin numbers would be different for both of these 2 electrons. One would have an up spin and the other a down spin.
Answer:Light bounces off of the mirror and then appears to come from behind the mirror.
Explanation:Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.
When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.
The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen..
Answer:
-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.
Explanation:
-Sodium Chloride has positively charged sodium ions, 
and negatively charged chloride ions, 
.
-Water on the other hand has positively charged Hydrogen ions,
and negatively charged Oxygen ions, 
due to the difference in electroneganivity.
-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:
Answer:
Quartz.
Explanation:
According to the characteristics given in the question the mineral must surely be Quartz.
Quartz does not react with hydrochloric acid.
Its is pink in color and has anon metallic luster. It has a specific gravity of 2.65. Quartz is continuous framework of SiO4 , with each oxygen being shared with two tetrahedra, giving an overall chemical formula of SiO2.
