Answer: The partial pressure of neon in the mixture is 263 mm Hg

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

p_{total}=p_{He}+p_{N_2}+p_{Ne}

Given : p_{total} =total pressure of gases = 815 mm Hg

p_{He} = partial pressure of helium = 201 mm Hg

p_{N_2} = partial pressure of nitrogen = 351 mm Hg

p_{Ne} = partial pressure of Neon = ?

putting in the values we get:

815mm Hg=201 mm Hg+351 mm Hg+p_{Ne}  

p_{Ne}=263mmHg

The partial pressure of neon in the mixture is 263 mm Hg

Improper use of cleaning agents in food-contact areas can add which of the following to food?
Nikitich [7]
I think the correct answer would be direct additives. Not proper handling of cleaning agents especially in areas where food are prepared or served would most likely add chemicals to the food which is harmful to the consumer. Hope this helps.

100 points!! Answer the question with all work shown. Picture is shown. Only #1 please.
Serhud [2]

To determine whether the crown was made of pure gold or not, we need to compare the density of gold (19.3 g/mL) to the density of the crown.

The formula for density is

Density=\frac{mass}{volume}

we know the mass of the crown is 714 grams and its volume is 38.3 mL. (Because it displaces 38.3 mL of water)

Using this information, we can plug the numbers into our density formula to solve for the density of the crown.

\frac{714 grams}{38.3 mL} = 18.6 g/mL

The density of the crown is 18.6 g/mL, thus the crown was not made of pure gold, as that has a density of 19.3 g/mL.  In conclusion, the goldsmith tried to screw over the king.
