Answer:

Based on the information, the compound is a phospholipid.

Explanation:

Phospholipids are made up of a fatty acid tail which is hydrophobic in nature and a head which comprises of phosphates that is hydrophilic in nature. Hence, phospholipids are amphiphilic compounds so they will be partially soluble in water and will allow water-soluble substances to mix with fats.

Hence, the composition of the substance described in the question confirms that is a phospholipid. As it's structure contains hydrocarbon and phosphorus and might also contain nitrogen.

Answer: In the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

Explanation:

It is known that more is the number of reactant molecules taking part in a chemical reaction more will be the number of collisions occur. As a result, more will be the rate of chemical reaction.

For example, When hydrogen peroxide dissociates into water and oxygen on addition of manganese oxide then increasing the number of reactants (hydrogen peroxide and manganese oxide) will also lead in the increase in rate of reaction.

Thus, we can conclude that in the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

Part a how many grams of xef6 are required to react with 0.579 l of hydrogen gas at 6.46 atm and 45°c in the reaction shown belo
Nina [5.8K]
First, let us find the corresponding amount of moles H₂ assuming ideal gas behavior.

PV = nRT
Solving for n,
n = PV/RT
n = (6.46 atm)(0.579 L)/(0.0821 L-atm/mol-K)(45 + 273 K)
n = 0.143 mol H₂

The stoichiometric calculations is as follows (MW for XeF₆ = 245.28 g/mol)
Mass XeF₆ = (0.143 mol H₂)(1 mol XeF₆/3 mol H₂)(245.28 g/mol) = <em>11.69 g</em>

Choose two different particles found in the air. Explain how they are different and how they are the same
BARSIC [14]

Answer:

Dust and smoke.

Explanation:

Dust and smoke are two different particles present in the air. Dust and smoke are different from one another due to their origin. Smoke formed from burning of materials while dust refers to the soil particles lifted by the wind due to their light weight. Dust and smoke are similar to each other due to their small in size, infinite number means uncountable and light weight.
