Strontium sulfide react with aqueus copper(ii) nitrate to form strontium (ii)nitrate and copper sulfide. the chemical equation is represented as follows
SrSO4(S) plus CU(NO3)2(aq) -->Sr(NO3)2(aq) PLUS CUSO4(s
the equation is balanced since both cupper and strontium have a valence of two.
Answer:-
Solution:- It is a volume unit conversion problem where we are asked to convert the volume from to microliters.
We know that:
= 1 mL
and,
Let's use these conversions factors for the desired conversion using dimensional as:
=
So, the answer is .
The molar mass of the unknown compound is calculated as follows
let the unknown gas be represented by letter Y
Rate of C2F4/ rate of Y = sqrt of molar mass of gas Y/ molar mass of C2F4
= (4.6 x10^-6/ 5.8 x10^-6) = sqrt of Y/ 100
remove the square root sign by squaring in both side
(4.6 x 10^-6 / 5.8 x10^-6)^2 = Y/100
= 0.629 =Y/100
multiply both side by 100
Y= 62.9 is the molar mass of unknown gas
