Answer:

The correct answer is vinegar and antacids.

Explanation:

An antacid is a substance, usually a base, that acts against acidity in an acid-base reaction.

The antacid alkalinizes the acid medium, increasing the pH. In this case, the vinegar has an acid pH, so the antacid would react with it by raising its pH, producing salts as a product of the reaction.

Have a nice day!

Describe a mechanical property of steel that characterizes its resistance to permanent deformation

strojnjashka [21]

The mechanical property of steel that characterizes its resistance to permanent deformation is ductility.

Am alloy is a substance prepared by adding one or more elements to a base or parent metal to obtain desirable properties.

Steel is an alloy of Iron and carbon in the composition of 99.8% and 0.2% respectively.

The mechanical or physical properties of steel include:

It is more malleable and ductile than iron.

It is harder and stronger.

it can withstand great stress and strain.

The ductility of a metal like steel is the ability of a metal to change its shape without breaking, that is, resistance to permanent deformation.

Therefore, the mechanical property of steel that characterizes its resistance to permanent deformation is ductility.

When nitroglycerine (227.1 g/mol) explodes, N2, CO2, H2O, and O2 gases are released initially. Assume that the gases from the ex

denis23 [38]

Answer:

a. 561L of N₂

b. 14,80L of CO₂

c. 715,0L of gases

Explanation:

The explosion of nitroglycerine gives the reaction:

4C₃H₅N₃O₉(s) → 6N₂(g) + 12CO₂(g) + 10H₂O(g) + O₂(g)

a. 4 moles of nitroglycerine produce 6 moles of N₂. Thus, 16,7 moles of nitrofglycerine produce:

16,7 moles C₃H₅N₃O₉ × (6 moles N₂ / 4 moles C₃H₅N₃O₉) = 25,05 moles N₂

At STP, 1 mole of gas occupies 22,4 L. 25,05 moles are:

25,05 moles N₂ × (22,4L / 1mole) = 561 L

b. 100,0g of C₃H₅N₃O₉ are:

100,0g C₃H₅N₃O₉ × (1mole / 227,1g) = 0,4403 moles of C₃H₅N₃O₉.

As 4 moles of C₃H₅N₃O₉ produce 6 mole of CO₂. Moles of CO₂ are:

0,4403 moles of C₃H₅N₃O₉ × ( 6mol CO₂ / 4mol C₃H₅N₃O₉) = 0,6605 moles CO₂ Again, as 1 mol of gas occupies 22,4L:

0,6605 mol CO₂ × (22,4L / 1mol) = 14,80 L

c. 1,000 kg ≈ 1000g of nytroglicerine are:

1000g C₃H₅N₃O₉ × (1mole / 227,1g) = 4,403 moles of C₃H₅N₃O₉.

As 4 moles of C₃H₅N₃O₉ produce 29 moles of gases. Moles of CO₂ are:

4,403 moles of C₃H₅N₃O₉ × ( 29mol gases / 4mol C₃H₅N₃O₉) = 31,92 moles of gases. Again, as 1 mol of gas occupies 22,4L:

31,92 mol CO₂ × (22,4L / 1mol) = 715,0 L 

I hope it helps!
