Answer:
(C3H4O3) x 2 = C6H8O6, the molecular formula for Vitamin C.
Answer:
Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism's genes. ... Genetic engineering uses the techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly.
Explanation:
The reaction equation is:
Zn + Pb(NO₃)₂ → Pb + Zn(NO₃)₂
The moles of lead are calculated using:
moles = concentration x volume
moles = 0.25 x 0.15
moles = 0.0375
The moles of zinc are: 1 / 65 = 0.015
We see from the equation that equimolar quantities of zinc and lead should be present. Therefore, lead is in excess and zinc is the limiting reactant.
The formula to find moles is:
n = m / M
m stands for mass, which in this case m = 64.92g
M stands for molar mass. You would need to look at the periodic table for each element of AgNO3 and add them together to get M.
n = 64.92 / 107.9 + 14.01 + 3(16)
= 0.382084...
= 0.38 moles (2 d.p)
Hope this helped!
