HCl + NaOH = NaCl + H₂O

m(HCl)=30g
m'(NaCl)=10g
M(HCl)=36.46 g/mol
M(NaCl)=58.44 g/mol

m(NaCl)/M(NaCl)=m(HCl)/M(HCl)

theoretical mass of sodium chloride
m(NaCl)=M(NaCl)m(HCl)/M(HCl)
m(NaCl)=58.44*30/36.46=48.09 g

the practical yield of the reaction
w=m'(NaCl)/m(NaCl)=m'(NaCl)M(HCl)/M(NaCl)m(HCl)

w=10*36.46/(58.44*30)=0.2080 (20.80%)

What are the various adverse effects of chemistry​
Kisachek [45]

<u>Answer:</u>

<em>Chemistry is the reaction between certain elements to </em><em>create a new compound</em><em> which may happen naturally but is mostly man made and hence has lot of good as well as </em><em>adverse effects.</em>

<u>Explanation:</u>

The <em>product or compound</em> that we get and the energy or outcome we receive is the ultimate result that decides whether chemical reaction that has happened is good or bad.

There are reactions that may cause pain and suffering to living beings and  are also able to<em> Infuse damage and destruction</em> are are adverse nature. they can also change the course of nature hence are are <em>dangerous. </em>

What is the number of molecules of c2h5oh in a 3m solution that contains 4.00kg h2o?
Veronika [31]
 The number  of C2H5OH  in a 3 m solution that contain 4.00kg H2O is calculate as below

M = moles of the solute/Kg  of water

that is 3M = moles of solute/ 4 Kg
multiply  both side by  4

moles of the  solute  is therefore = 12  moles

by use of Avogadro law constant

1 mole =6.02 x10^23  molecules

what  about 12 moles

=12 moles/1 moles  x 6.02 x10^23 = 7.224 x10^24 molecules
