Answer 1

Explanation:

i) fe+2hcl=>Fecl2+h2

1. Molecular mass of iron=56

n=7/56=1/8mol

1/8mol of Fe forms 1/8mol of FeCl2

(1/8)*(56+2*35.5)

( 1/8)*(56+71)

(1/8)*127

15.8g

II) 1mol of h2 from 2mol of hcl and 1mol of Fe

n=10/2=5moles

so 5moles of Fe needed

=5*56

=280g.

9)neutralisation means

N1V1=N2V2

n1*M1V1=n2*M2V2

1*M1*50=1*2*15

M1=30/50

I) M1=3/5=0.6mol/dm3

II)M1=(3/5)*molar mass g/dm3

M1=3/5*17

M1=51/5=10.2g/dm3
