335.6g of water will hold 725 grams of silver nitrate.
<h3><u>Explanation:</u></h3>
The saturated solution of a solvent is the solution which can't hold more of the solvent at a particular temperature and pressure under normal conditions, if more solvent are added, it will precipitate out.
Silver nitrate solution at the particular temperature and pressure contains 216 grams of silver nitrate in 100g of water.
So, 1 gram of silver nitrate is held in 100/216 grams of water.
So, 725grams of silver Nitrate is held in 100*725/216 grams of water = 335.6 grams of water.
This gives the saturated solution of silver nitrate again.
Sorry man i sad to see i’m late
Answer:
<em>Three (3) of the molecules are polar: </em>
<em> </em>
<em> </em>
<em>.</em>
Explanation:
Polar substances have their elements held together by a covalent bond that contain partially positive and negative charges, which results in a difference in the charges' electronegativity difference (usually ranging between 0.4 and 0.7).
- PCl5 is <u>non-polar</u> with a symmetric geometry
- CoS is <u>polar</u>
- XeO3 is <u>polar</u>, with a trigonal pyramidal molecular geometric
- SeBr2 is <u>polar</u> as the difference their electronegativity is about ).5
The number of protons = atomic number in Periodic table, so 35
The number of neutrons = mass number - number of protons = 79-35=44
The number of electrons = atomic number - 1 = 35-1 =34
