1 answer:

4 0

A functional group is a group of atoms that determines many of the properties of an organic molecule.
For example functional group for alcohol is hydroxyl group (-OH) and for carboxylic acid is carboxyl group (-COOH).
Alpha carbon is the first carbon atom after the carbon that attaches to the functional group.

Why is it important to keep high acid food away from zinc coated tub

denis23 [38]

The reactions that will take place will generate Zinc salts that will taint the food. Excessive levels of these salts can cause sickness, so it is very important to ensure food hygiene standards are met by keeping acidic foods away from damaging materials like zinc that will erode and get into the food.

Viefleur [7K]

A vessel that contains a mixture of nitrogen and butane has a pressure of 3.0 atm at 126.9 °C and a pressure of 1.0 atm at 0 °C. The mole fraction of nitrogen in the mixture is 0.33.

A vessel contains a gaseous mixture of nitrogen and butane. At 126.9 °C (400.1 K) the pressure is due to the mixture is 3.0 atm.

We can calculate the total number of moles using the ideal gas equation.

$P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{3.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.091 mol/L \times V$

At 0 °C (273.15 K), the pressure due to the gaseous nitrogen is 1.0 atm.

We can calculate the moles of nitrogen using the ideal gas equation.

$P \times V = n \times R \times T\\\\n = \frac{P \times V}{R \times T} = \frac{1.0 atm \times V}{0.082 atm.L/mol.K \times 400.1 K} = 0.030 mol/L \times V$

The mole fraction of nitrogen in the mixture is:

$X(N_2) = \frac{0.030 mol/L \times V}{0.091 mol/L \times V} = 0.33$

If acid gets on your skin or clothes, wash at once with?

ICE Princess25 [194]

water t because washing with sulfuric acid wouldn't actually get any of the acid off of you, same with oil, just soothe it momentarily and stop burning of the skin by creating a barrier to the acid. If you wash with soap it will burn even more by activating some enzymes in the acid (depending on kind of acid) so washing with water is most practical because it gets all of the acid off immediately to stop more burns from occurring. I would recommend washing with water and then pouring oil onto the burn, to create a barrier.
