Water’s molar mass is 18.01 g/mol. The molar mass of glycerol is 92.09 g/mol. At 25°C, glycerol is more viscous than water. Whic
amid [387]

Answer:

glycerol because it is more viscous and has a larger molar mass than water.

Explanation:

Viscosity depends on inter-molecular interactions.

The predominant inter-molecular force in water and glycerol is hydrogen bonding.

Hydrogen bond is an electrostatic attraction between two polar groups in which one group has hydrogen atom (H) and another group has highly electronegative atom such as nitrogen (like in this molecule), oxygen (O) or fluorine (F).

Which of the following is the balanced equation for P + O2 → P2O5? Question 3 options: A) 4P + O2 → 2P2O B) P + 5O2 → 2P2O5 C) 4
Luden [163]

Given equation:

P + O2 → P2O5

In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product

Reactants                                            Products

P = 1                                                       P = 2

O = 2                                                     O = 5

The balanced equation would be:

4P + 5O2 → 2P2O5

Reactants                                            Products

P = 4                                                      P = 4

O = 10                                                    O = 10

Ans: D)

At what volume of added acid is the phph calculated by working an equilibrium problem based on the initial concentration and kbk
nikdorinn [45]

In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

<h3>What is pH ?</h3>

pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.

<h3>What is Neutralization Reaction ? </h3>

Neutralization reaction is a chemical reaction in which an acid and a base react quantitatively with together.

Neutralization reaction equation:

Acid + Base → Salt + Water

Thus from the above conclusion we can say that In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

How is hess's law applied in calculating enthalpy
eimsori [14]

Answer:Hess's law states that the change of enthalpy in a chemical reaction (i.e. the heat of reaction at constant pressure) is independent of the pathway between the initial and final states. ... Hess's law allows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly.
