At 50 degrees Celsius and standard pressure inter-molecular forces of attraction are strongest in a sample of ethanoic acid.
Ethanoic acid has hydrogen atom bonded with a more electronegative atom; Oxygen. As a result, the molecule possesses strong intermolecular Hydrogen Bonds. Therefore; ethanoic acid, and all other carboxyllic acids have the tendency to form dimers.

Explanation:

PRESSURE AND TEMPERATURE RELATIONSHIP. In a closed system where volume is held constant, there is a direct relationship between Pressure and Temperature. ... For example, when the pressure increases then the temperature also increases. When the pressure decreases, then the temperature decreases.PRESSURE AND TEMPERATURE RELATIONSHIP.

Brandon is traveling in France. He weighs himself at a health club because he is concerned that he has eaten too many croissants

anastassius [24]

Answer:

For a: Yes, he has gained weight.

For b: The number of onions required is 1.

Explanation:

For a:

We are given:

Weight of Brandon checked earlier = 183 lb

Converting this into kilograms, we use the conversion factor:

1 kg = 2.205 lb

So, $183lb\times \frac{1kg}{2.205lb}=83kg$

And, weight of Brandon measured at the health club = 85.0 kg

As, the weight at the health club is more than the previous measured weight. So, Brandon has gained weight.

For b:

We are given:

Amount of diced onions a recipe calls = 125 g

Mass of 1 onion = 4 oz

Converting the mass of 1 onion to ounces, we use the conversion factor:

1 oz = 28.35 g

So, $4oz\times \frac{28.35g}{1oz}=113.4g$

To calculate the number of onions, we use the equation:

$\text{Number of onions}=\frac{\text{Mass of onion a recipe calls}}{\text{Mass of 1 onion}}$

$\text{Number of onions}=\frac{125g}{113.4g}=1.1\approx 1$

Hence, the number of onions required is 1.

Question 6: Iron metal and chlorine gas react to form iron (III) chloride: 2 Fe(s) + 3 Cl2 (g) → 2 FeCl3 (s)

Bas_tet [7]

10 gm of Fe will consumes 19 gm Cl₂ and will produces 29 gm FeCl₃.

What ois Theoretical yield ?

The quantity of a product obtained from a reaction is expressed in terms of the yield of the reaction.

The amount of product predicted by stoichiometry is called the theoretical yield, whereas the amount obtained actually is called the actual yield.
