Using the balanced equation below, how many grams of cesium xenon
heptafluoride would be produced
from the complete reaction of 37.8 g
cesium fluoride?

CsF + XeF6 => CsXeF7

Mass of CsXeF₇  = 99.3 g

Explanation:

Given data:

Mass of CsF = 37.8 g

Mass of CsXeF₇ produced = ?

Solution:

Balance chemical equation:

CsF + XeF₆   →    CsXeF₇

Number of moles of CsF:

Number of moles = mass/molar mass

Number of moles = 37.8 g/ 152 g/mol

Number of moles = 0.25 mol

Now we will compare the moles of CsF with CsXeF₇  from balance chemical equation:      

                   CsF             :         CsXeF₇

                    1                 :             1

                 0.25             :           0.25

Mass of CsXeF₇ :

Mass = number of moles × molar mass

Number of moles = 0.25 mol × 397.2 g/mol

Mass = 99.3 g

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
