Answer :
There is the commercial-grade, which is 70% strength in water, and it's pretty nasty stuff. It'll chew through your lab coat and give you burns you'll regret, as you'd expect from something that's rather stronger than nitric or sulfuric acid.
But it has other properties. The perchlorate anion is in a high oxidation state, and what goes up, must come down. A rapid drop in oxidation state, as chemists know, is often accompanied by loud noises and flying debris, particularly when the products formed are gaseous and have that pesky urge to expand. If you take the acid up to water-free concentrations, which is most highly not recommended, you'll probably want to wear chain mail, because it's tricky stuff. You can even go further and distill out the perchloric anhydride (dichlorine heptoxide) if you have no sense whatsoever. It's a liquid with a boiling point of around 80 C, and I'd like to shake the hand of whoever determined that property, assuming he has one left.
Answer: The type of deformation in which the object permanently changes size and shape without fracturing is called ductile deformation.
Explanation:
Ductile deformation is when the object bend or flow without fracturing like clay.
On the other hand, when the object breaks is considered brittle deformation.

The reaction is : C3H8 + 5O2 ===> 3CO2 + 4H2O
find the number of moles of H2O using the molar mass of H2O
moles of H2O = 75g/18.02 g/mol = 4.162 moles
go between the H2O and the propane to find the mole of propane
4.162 moles H2O its a 1 : 4 ratio so divide 4.162 / 4 = 1.041mol of propane
use this equation to find the volume of gas required : V = nRT/P
n is the moles of gas (propane)
R is the universal gas constant (0.082057338)
T is the temperature of the gas (273K)
V = (1.041) x (0.08206 L-atm/mol-K) x (273K)/(1 atm)
V = 23.3 L of C3H8
hope that helps
