Because they only partially ionize in solution, carboxylic acids are weak acids. When compared to a solution of a strong acid at the same concentration, their solutions contain fewer hydrogen ions. At the same concentration, the pH of a weak acid will be higher than that of a strong acid. This statement is true.
What is carboxylic acid ?A carboxylic acid is an organic acid with a carboxyl group attached to an R-group in organic chemistry. A carboxylic acid has the general formula RCOOH or RCO2H, where R refers to the alkyl, alkenyl, aryl, or other group. Carboxylic acids are found in abundance.
Carboxylic acids do this much more readily than most other classes of organic compounds, so they are referred to as stronger acids, despite being far weaker than the most important mineral acids—sulfuric (H2SO4), nitric (HNO3), and hydrochloric (HCL) (HCl).
Because of the following factors, carboxylic acid is weaker than HCl: Carboxylic acid ions do not completely dissociate in water. Carboxylic acid, as an organic acid, does not behave like other acids because it is not ionic.
Thus, carboxylic acids are weak acids.

A plot of the Maxwell distribution of velocities for a number of different gases measured at the same temperature shows that
Answer:
as molecular mass increases, more molecules have speeds close to their average speed.
Explanation:
A plot of the Maxwell distribution of velocities for several different gases measured at the same temperature shows that "as molecular mass increases, more molecules have speeds close to their average speed."
This is evident in the fact that the Maxwell distribution of speeds for a given selection of gas at a given temperature shows certain traits if one of the main variables is changed, such as
1. Mass: The proportion of speeds for a given selection of gas is narrower and the average speed is lower for gas of higher molecular weight.
2. Temperature: The proportion of speeds for a given selection of gas is wider and the average speed is higher as the temperature of a gas increases.
How many moles of O2will be produced from 6.2 moles of water?
Answer:
I hope This will help you....and please mark me as Brilliant
Explanation:
The formula, H2O tels us that there are the same number of moles of Oxygen as there are of water. The (understood )molecular coefficient of H2O is 1. The (understood ) coefficient of O in the formula is also 1. The number of moles of oxygen is the same as the number of moles of water. This is moles of oxygen atoms. If the question wants moles of oxygen gas, O2, then it will be half as many I think that is what they want, so I would answer 3.1 moles of O2.

4NO + 3O2 + 2H2O = 2.4 moles of NO 2.4 moles of O2 and 2.4 moles of H2O react and 2.0 moles of HNO3 are recovered from the reaction. what is the percent yield of this reaction ?
Answer:
83%
Explanation:
Percent yield is 100 times the ratio between actual yield (2.0moles HNO₃) and theoretical yield. To find theoretical yield:
As you can see in the reaction:
4NO + 3O₂ + 2H₂O → 4HNO₃
4 moles of NO are required when 3 moles of O₂ and 2 moles of H₂O reacts. As equal moles of each reactant are added, the limiting reactant is NO because is the substance that requires more moles to react.
2.4 mol NO produce 2.4 mol HNO₃-Because 4 moles of NO produce 4 moles of HNO₃. That means theoretical yield is 2.4 moles and percent yield is:
2.0 moles / 2.4 moles * 100 = 83%

A wooden plank has a mass of 100kg force of 20 n was used to move it what is its acceleration
Answer:
a= 0.2m/s²
Explanation:
Fnet = ma
20 = 100a (divide both sides by 100)
a = 0.2m/s²
A wooden plank has a mass of 100 kg force of 20 Nwllhave the acceleration of 0.2 m/s².
What is Acceleration ?Acceleration is the rate of change of the velocity of an object with respect to time.
Accelerations are vector quantities.
The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
We know,
F= ma ,
where
F is force , M is mass , A is acceleration.For 100kg ,
20 = 100 x A
A = 20/100
A = 0.2 m/s².
Therefore, A wooden plank has a mass of 100 kg force of 20 Nwllhave the acceleration of 0.2 m/s².

Where is most of an atom's atomic mass?
Answer:
The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m—about 100,000 times smaller.
