for 2Na (s) +Cl2(g)->2NaCl(s) how many grams of sodium chloride will be made from 115 g of sodium metal when when reacted wit
alexandr1967 [171]

 The grams  of sodium   chloride that will be made is 292.5 g


<u><em>calculation</em></u>

2Na  +Cl₂ → 2NaCl

step 1: calculate the  moles of Na

moles  =   mass/molar mass

From periodic table the  molar mass  of Na = 23 g/mol

moles = 115 g/23 g /mol =  5  moles

Step 2 : use the mole ratio to determine the  moles of NaCl

Na:NaCl   is  2:2 = 1:1  therefore the moles of NaCl  is also= 5 moles


Step  3: find the mass of NaCl

mass= moles  x molar mass

The  molar mass of NaCl = 23 + 35 .5 =58.5 g/mol

mass= 5 moles x 58.5 g/mol =292.5  g

In what beaker does the sugar dissolve the fastest? ( particle size, temp. of water, condition(stir/no stir), etc).
Vsevolod [243]
Temperature. In case you have ever baked, you can relate to this. For example, when you make caramel, you simply put the caramel on a boiling hot pan and sit back and watch it. It always goes fastest this way.
