<span>If volume = weight divided by density - we already know the weight is 15 grams, and that the density is 7.8 grams. We would plug this into the formula to get 15g divided by 7.8cm3 with proper units and significant figures - we would end up with 1.92cm cubed.</span>

26. If a saturated solution of AgNO3 at 20°C contains 216 g AgNO3 per 100.0 g of water, what mass of water could
givi [52]

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.

How many of the following molecules are polar? Pcl5 cos xeo3 sebr2
klasskru [66]

Answer:

<em>Three (3) of the molecules are polar: </em>CoS,<em> </em>XeO_{3},<em> </em>SeBr_{2}<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

How many protons, electrons, and neutrons does the following isotope contain? 79Br+
stellarik [79]

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
