The element phosphorus is located to the right of the element magnesium along the same period in the periodic table. Which best describes the relationship between the elements? A. Magnesium has a larger atomic number. B. Phosphorus has a larger atomic mass. C. Magnesium is in the same category as phosphorus D. Phosphorus has similar chemical properties as magnesium

Step-by-step answer

P Answered by PhD

B)Phosphorus has a larger atomic mass.

As we move right in the periodic table, both atomic number and atomic mass increases. Magnesium comes under S-block elements (Group 2) and Phosphorus comes under P-block elements (Group-15).

A binary star system is made of stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to . Astronomers can also spot the dimmer star by observing a phenomenon called a(n) binary. This happens when the dim star passes in front of the bright star.

Step-by-step answer

Using the term water potential, explain why the onions ; (i)gained mass when soaked in dilute solutions of sodium chloride (ii)lost mass when soaked in concentrated solutions of sodium chloride

Step-by-step answer

P Answered by PhD

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis. Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
